What is the capacity of the battery?
The capacity of the battery refers to the amount of electricity that the active material in the battery can participate in the electrochemical reaction is called the capacity of the battery, that is, the amount of charge that the battery can hold after charging. The unit is “Ah” (Ah) and 1 A (A). The current is discharged for 1 hour, and the capacity is 1 ampere hour (Ah). Assuming that the average current is 4A, the discharge time is 3 hours when the battery is discharged at the termination voltage of the battery, and the battery capacity is 12Ah (the discharge is not calculated here) effectiveness).
What is battery internal resistance?
It refers to the resistance to the current flowing through the battery when the battery is working. There are two parts: ohmic internal resistance and polarization internal resistance. Large internal resistance of the battery will cause the battery’s discharge working voltage to decrease and shorten the discharge time. The internal resistance is mainly affected by the battery material, manufacturing process, battery structure and other factors. Is an important parameter to measure battery performance.

How to maintain the consistency of the battery pack?
Although the lead-acid battery has been strictly selected when it leaves the factory, after a certain period of use, the non-uniformity will appear and gradually increase. The charger can’t recognize or supplement the undercharge. How to balance the battery capacity? It must be performed by humans. The user measures the open circuit voltage of each battery periodically and irregularly during the middle and late periods of battery pack use. For lower voltages, recharge separately to make the voltage and capacity consistent with other batteries, and try to reduce their gap.
Can I do a partial replacement of my batteries?
لا يوصى باستبدال البطارية الجزئي لبنوك بطاريات الرصاص الحمضية.
Are you a battery manufacturer, and do you produce the plates by yourself ?

Does your battery develop a memory?
لا تطور بطاريات الرصاص الحمضية أي نوع من الذاكرة. هذا يعني أنك لست مضطرًا إلى التفريغ العميق للبطارية أو تفريغها تمامًا قبل إعادة شحنها. للحصول على أفضل عمر وأداء ، نوصي عمومًا بتفريغ 20 إلى 50% من السعة المقدرة للبطاريات على الرغم من أن البطارية قابلة للدوران إلى 90%.

How to charge a battery to be at 100% state of charge healthiest?
You may have heard it said “you need a 3 stage charger”. We’ve said it, and we’ll say it again. The best kind of charger to use on your battery is a 3 stage charger. They are also called “smart chargers” or “micro processor controlled chargers”. Basically, these types of chargers are safe, easy to use, and will not overcharge your battery. Almost all of the chargers we sell are 3 stage chargers. Okay, so it’s hard to deny that 3 stage chargers work and they work well. But here’s the million dollar question: What are the 3 stages? What makes these chargers so different and efficient? Is it really worth it? Lets find out by going through each stage, one by one:Stage 1 | Bulk ChargeThe primary purpose of a battery charger is to recharge a battery. This first stage is typically where the highest voltage and amperage the charger is rated for will actually be used. The level of charge that can be applied without overheating the battery is known as the battery’s natural absorption rate. For a typical 12 volt AGM battery, the charging voltage going into a battery will reach 14.6-14.8 volts, while flooded batteries can be even higher. For the gel battery, the voltage should be no more than 14.2-14.3 volts. If the charger is a 10 amp charger, and if the battery resistance allows for it, the charger will put out a full 10 amps. This stage will recharge batteries that are severely drained. There is no risk of overcharging in this stage because the battery hasn’t even reached full yet. Stage 2 | Absorption ChargeSmart chargers will detect voltage and resistance from the battery prior to charging. After reading the battery the charger determines which stage to properly charge at. Once the battery has reached 80%* state of charge, the charger will enter the absorption stage. At this point most chargers will maintain a steady voltage, while the amperage declines. The lower current going into the battery safely brings up the charge on the battery without overheating it.This stage takes more time. For instance, the last remaining 20% of the battery takes much longer when compared to the first 20% during the bulk stage. The current continuously declines until the battery almost reaches full capacity.*Actual state of charge Absorption Stage will enter will vary from charger to chargerStage 3 | Float ChargeSome chargers enter float mode as early as 85% state of charge but others begin closer to 95%. Either way, the float stage brings the battery all the way through and maintains the 100% state of charge. The voltage will taper down and maintain at a steady 13.2-13.4 volts, which is the maximum voltage a 12 volt battery can hold. The current will also decrease to a point where it’s considered a trickle. That’s where the term “trickle charger” comes from. It’s essentially the float stage where there is charge going into the battery at all times, but only at a safe rate to ensure a full state of charge and nothing more. Most smart chargers do not turn off at this point, yet it is completely safe to leave a battery in float mode for months to even years at a time. It’s the healthiest thing for a battery to be at 100% state of charge. We’ve said it before and we’ll say it again. The best kind of charger to use on a battery is a 3 stage smart charger. They are easy to use and worry free. You don’t ever have to worry about leaving the charger on the battery for too long. In fact, it’s best if you DO leave it on. When a battery is not at a fully charged state, sulfate crystal build on the plates and this robs you of power. If you leave your powersports in the shed during off-season or for vacations, please connect the battery to a 3 stage charger. This will ensure that your battery will be ready to start whenever you are.
Does over-discharging damage batteries?
Over-discharging is a problem which originates from insufficient battery capacity causing the batteries to be overworked. Discharges deeper than 50% (in reality well below 12.0 Volts or 1.200 Specific Gravity) significantly shorten the Cycle Life of a battery without increasing the usable depth of cycle. Infrequent or inadequate recharging can also cause over discharging symptoms called SULFATION. Despite that charging equipment is regulating back properly, over discharging symptoms are displayed as loss of battery capacity and lower than normal specific gravity. Sulfate occurs when sulfur from the electrolyte combines with the lead on the plates and forms lead-sulfate. Once this condition becomes occurs, marine battery chargers will not remove the hardened sulfate. Sulfate can usually be removed by a proper desulfation or equalization charge with external manual battery chargers. To accomplish this task, the flooded plate batteries must be charged at 6 to 10 amps. at 2.4 to 2.5 volts per cell until all cells are gassing freely and their specific gravity returns to their full charge concentration. Sealed AGM batteries should be brought to 2.35 volts per cell and then discharged to 1.75 volts per cell and then this process must be repeated until the capacity returns to the battery. Gel batteries may not recover. In most cases, the battery may be returned to complete its service life.CHARGING Alternators and float battery chargers including regulated photo voltaic chargers have automatic controls which taper the charge rate as the batteries come up in charge. It should be noted that a decrease to a few amperes while charging does not mean that the batteries have been fully charged. Battery chargers are of three types. There is the manual type, the trickle type, and the automatic switcher type.
What are primary and secondary batteries?
البطاريات الأساسية هي بطاريات جافة عادية ، يمكن استخدامها مرة واحدة فقط. البطاريات الثانوية تسمى أيضًا البطاريات القابلة لإعادة الشحن ، ويمكن شحنها وتفريغها للعديد من الوقت. بطارياتنا هي بطاريات ثانوية.
What is battery rating?
The most common battery rating is the AMP-HOUR RATING. This is a unit of measurement for battery capacity, obtained by multiplying a current flow in amperes by the time in hours of discharge. (Example: A battery which delivers 5 amperes for 20 hours delivers 5 amperes times 20 hours, or 100 ampere-hours.)Manufacturers use different discharge periods to yield an different Amp-Hr. Rating for the same capacity batteries, therefore, the Amp-Hr. Rating has little significance unless qualified by the number of hours the battery is discharged. For this reason Amp-Hour Ratings are only a general method of evaluating a battery’s capacity for selection purposes. The quality of internal components and technical construction within the battery will generate different desired characteristics without effecting its Amp-Hour Rating. For instance, there are 150 Amp-Hour batteries that will not support an electrical load overnight and if called upon to do so repetitively, will fail early in their life. Conversely, there are 150 Amp-Hour batteries that will operate an electrical load for several days before needing recharging and will do so for years. The following ratings must be examined in order to evaluate and select the proper battery for a specific application: COLD CRANKING AMPERAGE and RESERVE CAPACITY are ratings used by the industry to simplify battery selection.
What does the Reserve Capacity rating mean and how does it apply to cycle?
Reserve capacity is the number of minutes a battery can maintain a useful voltage under a 25 ampere discharge. The higher the minute rating, the greater the battery’s ability to run lights, pumps, inverters, and electronics for a longer period before recharging is necessary. The 25 Amp. Reserve Capacity Rating is more realistic than Amp-Hour or CCA as a measurement of capacity for deep cycle service. Batteries promoted on their high Cold Cranking Ratings are easy and inexpensive to build. The market is flooded with them, however their Reserve Capacity, Cycle Life (the number of discharges and charges the battery can deliver) and Service life are poor. Reserve Capacity is difficult and costly to engineer into a battery and requires higher quality cell materials.
What is discharge efficiency?
تشير كفاءة التفريغ إلى نسبة الطاقة الفعلية إلى السعة الاسمية عند تفريغ البطارية عند جهد النهاية في ظروف تفريغ معينة. يتأثر بشكل أساسي بعوامل مثل معدل التفريغ ودرجة الحرارة البيئية والمقاومة الداخلية. بشكل عام ، كلما زاد معدل التفريغ ، انخفضت كفاءة التفريغ ؛ كلما انخفضت درجة الحرارة ، انخفضت كفاءة التفريغ.
What is the difference between float and cycle applications?
يتطلب تطبيق الطفو أن تكون البطارية في حالة شحن مستمر مع تفريغ عرضي. تطبيقات دورة شحن وتفريغ البطارية على أساس منتظم.

أ: تشير سعة البطارية إلى كمية الكهرباء التي يمكن أن تشاركها المادة النشطة في البطارية في التفاعل الكهروكيميائي ، وتسمى سعة البطارية ، أي مقدار الشحن الذي يمكن أن تحمله البطارية بعد الشحن. الوحدة هي "آه" (آه) و 1 أ (أ). يتم تفريغ التيار لمدة ساعة ، والقدرة 1 أمبير ساعة (آه). بافتراض أن متوسط التيار هو 4A ، فإن وقت التفريغ يكون 3 ساعات عند تفريغ البطارية بجهد إنهاء البطارية ، وسعة البطارية هي 12Ah (لم يتم حساب التفريغ هنا).
أ: يشير إلى مقاومة التيار المتدفق عبر البطارية عندما تعمل البطارية. هناك جزأين: المقاومة الداخلية الأومية والمقاومة الداخلية للاستقطاب. ستؤدي المقاومة الداخلية الكبيرة للبطارية إلى تقليل جهد عمل تفريغ البطارية وتقليل وقت التفريغ. تتأثر المقاومة الداخلية بشكل أساسي بمواد البطارية وعملية التصنيع وهيكل البطارية وعوامل أخرى. هي معلمة مهمة لقياس أداء البطارية.
أ: أثناء عملية شحن البطارية ، يتم تحويل جزء من الطاقة الكهربائية إلى طاقة كيميائية ، ويتم تحويل جزء من الطاقة الكهربائية إلى طاقة حرارية وطاقة أخرى. من الطبيعي أن يتم تسخين البطارية القابلة لإعادة الشحن ، ولكن عندما تكون درجة الحرارة عالية جدًا ، يجب عليك التحقق مما إذا كان تيار الشحن كبيرًا جدًا أو حدوث دائرة كهربائية قصيرة داخل البطارية.

أ: على الرغم من أن بطارية الرصاص الحمضية قد تم اختيارها بدقة عندما تغادر المصنع ، إلا أنه بعد فترة معينة من الاستخدام ، سيظهر عدم التماثل ويزداد تدريجياً. لا يستطيع الشاحن التعرف على الشحن المنخفض أو استكماله. كيف توازن سعة البطارية؟ يجب أن يؤديها البشر. يقيس المستخدم جهد الدائرة المفتوحة لكل بطارية بشكل دوري وغير منتظم خلال الفترات المتوسطة والمتأخرة من استخدام حزمة البطارية. بالنسبة للجهد المنخفض ، أعد الشحن بشكل منفصل لجعل الجهد والسعة متوافقين مع البطاريات الأخرى ، وحاول تقليل الفجوة بينهما.
أ: لا تطور بطاريات الرصاص الحمضية أي نوع من الذاكرة. هذا يعني أنك لست مضطرًا إلى التفريغ العميق للبطارية أو تفريغها تمامًا قبل إعادة شحنها. للحصول على أفضل عمر وأداء ، نوصي عمومًا بتفريغ 20 إلى 50% من السعة المقدرة للبطاريات على الرغم من أن البطارية قابلة للدوران إلى 90%.

أ: ربما سمعت أنه يقول "تحتاج إلى شاحن ثلاثي المراحل". قلناها ، وسنقولها مرة أخرى. أفضل نوع من الشاحن لاستخدامه على بطاريتك هو شاحن ثلاثي المراحل. وتسمى أيضًا "أجهزة الشحن الذكية" أو "أجهزة الشحن التي يتم التحكم فيها بواسطة معالج دقيق". في الأساس ، هذه الأنواع من أجهزة الشحن آمنة وسهلة الاستخدام ولن تفرط في شحن البطارية. جميع أجهزة الشحن التي نبيعها تقريبًا عبارة عن أجهزة شحن ثلاثية المراحل. حسنًا ، من الصعب إنكار أن أجهزة الشحن ذات 3 مراحل تعمل بشكل جيد. لكن إليكم سؤال المليون دولار: ما هي المراحل الثلاث؟ ما الذي يجعل أجهزة الشحن هذه مختلفة وفعالة؟ هل حقا يستحق ذلك؟ دعنا نكتشف من خلال المرور بكل مرحلة ، واحدة تلو الأخرى:
المرحلة 1 | الشحن بالجملة
الغرض الأساسي من شاحن البطارية هو إعادة شحن البطارية. هذه المرحلة الأولى هي عادةً حيث سيتم استخدام أعلى جهد وأمبير تم تقييمه للشاحن بالفعل. يُعرف مستوى الشحن الذي يمكن تطبيقه دون ارتفاع درجة حرارة البطارية بمعدل الامتصاص الطبيعي للبطارية. بالنسبة لبطارية AGM نموذجية بجهد 12 فولت ، سيصل جهد الشحن في البطارية إلى 14.6-14.8 فولت ، في حين أن البطاريات المغمورة يمكن أن تكون أعلى من ذلك. بالنسبة لبطارية الهلام ، يجب ألا يزيد الجهد عن 14.2-14.3 فولت. إذا كان الشاحن عبارة عن شاحن 10 أمبير ، وإذا كانت مقاومة البطارية تسمح بذلك ، فسيقوم الشاحن بإخراج 10 أمبير كاملة. ستقوم هذه المرحلة بإعادة شحن البطاريات التي تم تفريغها بشدة. لا يوجد خطر من زيادة الشحن في هذه المرحلة لأن البطارية لم تصل إلى مستوى الشحنة بعد.
المرحلة 2 | رسوم الامتصاص
ستكتشف أجهزة الشحن الذكية الجهد والمقاومة من البطارية قبل الشحن. بعد قراءة البطارية ، يحدد الشاحن المرحلة التي سيتم الشحن فيها بشكل صحيح. بمجرد وصول البطارية إلى حالة الشحن 80% * ، سيدخل الشاحن في مرحلة الامتصاص. في هذه المرحلة ، ستحافظ معظم أجهزة الشحن على جهد ثابت ، بينما ينخفض التيار. يؤدي التيار المنخفض الداخل إلى البطارية إلى إحضار شحن البطارية بأمان دون ارتفاع درجة حرارتها.
هذه المرحلة تستغرق وقتًا أطول. على سبيل المثال ، تستغرق آخر 20% متبقية من البطارية وقتًا أطول مقارنةً بأول 20% أثناء مرحلة السائبة. ينخفض التيار باستمرار حتى تصل البطارية إلى طاقتها الكاملة تقريبًا.
* الحالة الفعلية للشحن ستدخل مرحلة الامتصاص من شاحن لآخر
المرحلة 3 | تعويم المسؤول
تدخل بعض أجهزة الشحن في وضع التعويم في وقت مبكر مثل حالة الشحن 85% ولكن البعض الآخر يبدأ بالقرب من 95%. في كلتا الحالتين ، تعمل مرحلة التعويم على توصيل البطارية بالكامل وتحافظ على حالة الشحن 100%. سوف يتناقص الجهد ويحتفظ بثبات 13.2-13.4 فولت ، وهو أقصى جهد يمكن أن تحمله بطارية 12 فولت. سينخفض التيار أيضًا إلى النقطة التي يعتبر فيها هزيلة. هذا هو المكان الذي يأتي منه مصطلح "شاحن هزيل". إنها في الأساس مرحلة التعويم حيث يتم شحن البطارية في جميع الأوقات ، ولكن بمعدل آمن فقط لضمان حالة الشحن الكاملة ولا شيء أكثر من ذلك. لا يتم إيقاف تشغيل معظم أجهزة الشحن الذكية في هذه المرحلة ، ولكن من الآمن تمامًا ترك البطارية في وضع التعويم لأشهر وحتى سنوات في المرة الواحدة.
من الأصح أن تكون البطارية بحالة شحن 100%.
قلناها من قبل وسنقولها مرة أخرى. أفضل نوع من الشاحن لاستخدامه على البطارية هو a شاحن ذكي 3 مراحل. إنها سهلة الاستخدام ولا تقلق. لا داعي للقلق مطلقًا بشأن ترك الشاحن على البطارية لفترة طويلة. في الواقع ، من الأفضل تركه. عندما لا تكون البطارية في حالة شحن كامل ، فإن بلورات الكبريتات تتجمع على الألواح وهذا يسلبك الطاقة. إذا تركت رياضات الطاقة الخاصة بك في السقيفة أثناء غير موسمها أو لقضاء الإجازات ، فيرجى توصيل البطارية بشاحن ثلاثي المراحل. سيضمن ذلك أن تكون بطاريتك جاهزة لبدء التشغيل متى أردت ذلك.
أ: الإفراط في التفريغ مشكلة تنشأ من عدم كفاية سعة البطارية مما يؤدي إلى زيادة طاقتها. تفريغ أعمق من 50% (في الواقع أقل بكثير من 12.0 فولت أو 1.200 جاذبية محددة) تقصر بشكل كبير من عمر دورة البطارية دون زيادة عمق الدورة القابلة للاستخدام. يمكن أن تؤدي إعادة الشحن بشكل غير متكرر أو غير كافٍ أيضًا إلى ظهور أعراض الإفراط في التفريغ التي تسمى SULFATION. على الرغم من إعادة تنظيم معدات الشحن بشكل صحيح ، يتم عرض أعراض الإفراط في التفريغ على أنها فقدان سعة البطارية وأقل من الجاذبية النوعية العادية. تحدث الكبريتات عندما يتحد الكبريت من المنحل بالكهرباء مع الرصاص الموجود على الألواح ويشكل كبريتات الرصاص. بمجرد حدوث هذه الحالة ، لن تقوم شواحن البطاريات البحرية بإزالة الكبريتات المتصلدة. يمكن عادةً إزالة الكبريتات عن طريق إزالة الكبريت أو شحن المعادلة المناسب باستخدام شواحن البطاريات اليدوية الخارجية. لإنجاز هذه المهمة ، يجب شحن البطاريات المغمورة من 6 إلى 10 أمبير. من 2.4 إلى 2.5 فولت لكل خلية حتى يتم إطلاق الغازات في جميع الخلايا بحرية وتعود جاذبيتها النوعية إلى تركيز شحنتها الكامل. يجب إحضار بطاريات AGM المختومة إلى 2.35 فولت لكل خلية ثم تفريغها إلى 1.75 فولت لكل خلية ومن ثم يجب تكرار هذه العملية حتى تعود السعة إلى البطارية. قد لا تتعافى بطاريات الجل. في معظم الحالات ، قد يتم إرجاع البطارية لإكمال عمرها التشغيلي. شحن المولدات وشواحن البطاريات العائمة بما في ذلك الشواحن الفولتية الضوئية المنظمة لها أدوات تحكم أوتوماتيكية تقلل من معدل الشحن مع بدء شحن البطاريات. وتجدر الإشارة إلى أن الانخفاض إلى بضعة أمبيرات أثناء الشحن لا يعني أن البطاريات مشحونة بالكامل. شواحن البطاريات من ثلاثة أنواع. هناك نوع يدوي ، نوع هزيلة ، ونوع التبديل التلقائي.
أ: البطاريات الأساسية هي بطاريات جافة عادية ، يمكن استخدامها مرة واحدة فقط. البطاريات الثانوية تسمى أيضًا البطاريات القابلة لإعادة الشحن ، ويمكن شحنها وتفريغها للعديد من الوقت. بطارياتنا هي بطاريات ثانوية.
أ: تصنيف البطارية الأكثر شيوعًا هو AMP-HOUR RATING. هذه وحدة قياس لسعة البطارية ، يتم الحصول عليها بضرب تدفق التيار بالأمبير بالوقت في ساعات التفريغ. (مثال: بطارية توفر 5 أمبير لمدة 20 ساعة 5 أمبير مرات 20 ساعة ، أو 100 أمبير-ساعة.)
يستخدم المصنعون فترات تفريغ مختلفة لإنتاج Amp-Hr مختلف. تصنيف لنفس سعة البطاريات ، لذلك ، Amp-Hr. التصنيف له أهمية قليلة ما لم يتم تحديده بعدد ساعات تفريغ البطارية. لهذا السبب ، فإن تقييمات Amp-Hour ليست سوى طريقة عامة لتقييم سعة البطارية لأغراض الاختيار. ستولد جودة المكونات الداخلية والبنية الفنية داخل البطارية خصائص مرغوبة مختلفة دون التأثير على تصنيف أمبير ساعة. على سبيل المثال ، هناك 150 بطارية Amp-Hour لن تدعم الحمل الكهربائي بين عشية وضحاها ، وإذا طُلب منها القيام بذلك بشكل متكرر ، فسوف تفشل في وقت مبكر من حياتها. على العكس من ذلك ، هناك 150 بطارية أمبير في الساعة تعمل بحمل كهربائي لعدة أيام قبل أن تحتاج إلى إعادة الشحن وستقوم بذلك لسنوات. يجب فحص التصنيفات التالية من أجل تقييم واختيار البطارية المناسبة لتطبيق معين: COLD CRANKING AMPERAGE و RESERVE CAPACITY من التصنيفات المستخدمة من قبل الصناعة لتبسيط اختيار البطارية.
أ: السعة الاحتياطية هي عدد الدقائق التي يمكن للبطارية أن تحافظ فيها على جهد كهربائي مفيد تحت تفريغ 25 أمبير. كلما زاد تصنيف الدقائق ، زادت قدرة البطارية على تشغيل المصابيح والمضخات والمحولات والإلكترونيات لفترة أطول قبل إعادة الشحن. ال 25 امبير. يعتبر تصنيف القدرة الاحتياطية أكثر واقعية من Amp-Hour أو CCA كمقياس لقدرة خدمة الدورة العميقة. البطاريات التي يتم الترويج لها بناءً على تقييمات Cranking العالية الخاصة بها سهلة وغير مكلفة في البناء. السوق مغمور بهم ، لكن السعة الاحتياطية ، ودورة الحياة (عدد عمليات التفريغ والشحن التي يمكن للبطارية تقديمها) وعمر الخدمة ضعيف. يعد تصميم السعة الاحتياطية أمرًا صعبًا ومكلفًا في تصميم بطارية وتتطلب مواد خلوية عالية الجودة.
أ: تشير كفاءة التفريغ إلى نسبة الطاقة الفعلية إلى السعة الاسمية عند تفريغ البطارية عند جهد النهاية في ظروف تفريغ معينة. يتأثر بشكل أساسي بعوامل مثل معدل التفريغ ودرجة الحرارة البيئية والمقاومة الداخلية. بشكل عام ، كلما زاد معدل التفريغ ، انخفضت كفاءة التفريغ ؛ كلما انخفضت درجة الحرارة ، انخفضت كفاءة التفريغ.

أسئلة وأجوبة
Search battery, charging and product support questions.
What is the capacity of the battery?
The capacity of the battery refers to the amount of electricity that the active material in the battery can participate in the electrochemical reaction is called the capacity of the battery, that is, the amount of charge that the battery can hold after charging. The unit is “Ah” (Ah) and 1 A (A). The current is discharged for 1 hour, and the capacity is 1 ampere hour (Ah). Assuming that the average current is 4A, the discharge time is 3 hours when the battery is discharged at the termination voltage of the battery, and the battery capacity is 12Ah (the discharge is not calculated here) effectiveness).
What is battery internal resistance?
It refers to the resistance to the current flowing through the battery when the battery is working. There are two parts: ohmic internal resistance and polarization internal resistance. Large internal resistance of the battery will cause the battery’s discharge working voltage to decrease and shorten the discharge time. The internal resistance is mainly affected by the battery material, manufacturing process, battery structure and other factors. Is an important parameter to measure battery performance.
Can I fast charge my battery?

How to maintain the consistency of the battery pack?
Although the lead-acid battery has been strictly selected when it leaves the factory, after a certain period of use, the non-uniformity will appear and gradually increase. The charger can’t recognize or supplement the undercharge. How to balance the battery capacity? It must be performed by humans. The user measures the open circuit voltage of each battery periodically and irregularly during the middle and late periods of battery pack use. For lower voltages, recharge separately to make the voltage and capacity consistent with other batteries, and try to reduce their gap.
Can I do a partial replacement of my batteries?
لا يوصى باستبدال البطارية الجزئي لبنوك بطاريات الرصاص الحمضية.

Does your battery develop a memory?
لا تطور بطاريات الرصاص الحمضية أي نوع من الذاكرة. هذا يعني أنك لست مضطرًا إلى التفريغ العميق للبطارية أو تفريغها تمامًا قبل إعادة شحنها. للحصول على أفضل عمر وأداء ، نوصي عمومًا بتفريغ 20 إلى 50% من السعة المقدرة للبطاريات على الرغم من أن البطارية قابلة للدوران إلى 90%.

How to charge a battery to be at 100% state of charge healthiest?
You may have heard it said “you need a 3 stage charger”. We’ve said it, and we’ll say it again. The best kind of charger to use on your battery is a 3 stage charger. They are also called “smart chargers” or “micro processor controlled chargers”. Basically, these types of chargers are safe, easy to use, and will not overcharge your battery. Almost all of the chargers we sell are 3 stage chargers. Okay, so it’s hard to deny that 3 stage chargers work and they work well. But here’s the million dollar question: What are the 3 stages? What makes these chargers so different and efficient? Is it really worth it? Lets find out by going through each stage, one by one:Stage 1 | Bulk ChargeThe primary purpose of a battery charger is to recharge a battery. This first stage is typically where the highest voltage and amperage the charger is rated for will actually be used. The level of charge that can be applied without overheating the battery is known as the battery’s natural absorption rate. For a typical 12 volt AGM battery, the charging voltage going into a battery will reach 14.6-14.8 volts, while flooded batteries can be even higher. For the gel battery, the voltage should be no more than 14.2-14.3 volts. If the charger is a 10 amp charger, and if the battery resistance allows for it, the charger will put out a full 10 amps. This stage will recharge batteries that are severely drained. There is no risk of overcharging in this stage because the battery hasn’t even reached full yet. Stage 2 | Absorption ChargeSmart chargers will detect voltage and resistance from the battery prior to charging. After reading the battery the charger determines which stage to properly charge at. Once the battery has reached 80%* state of charge, the charger will enter the absorption stage. At this point most chargers will maintain a steady voltage, while the amperage declines. The lower current going into the battery safely brings up the charge on the battery without overheating it.This stage takes more time. For instance, the last remaining 20% of the battery takes much longer when compared to the first 20% during the bulk stage. The current continuously declines until the battery almost reaches full capacity.*Actual state of charge Absorption Stage will enter will vary from charger to chargerStage 3 | Float ChargeSome chargers enter float mode as early as 85% state of charge but others begin closer to 95%. Either way, the float stage brings the battery all the way through and maintains the 100% state of charge. The voltage will taper down and maintain at a steady 13.2-13.4 volts, which is the maximum voltage a 12 volt battery can hold. The current will also decrease to a point where it’s considered a trickle. That’s where the term “trickle charger” comes from. It’s essentially the float stage where there is charge going into the battery at all times, but only at a safe rate to ensure a full state of charge and nothing more. Most smart chargers do not turn off at this point, yet it is completely safe to leave a battery in float mode for months to even years at a time. It’s the healthiest thing for a battery to be at 100% state of charge. We’ve said it before and we’ll say it again. The best kind of charger to use on a battery is a 3 stage smart charger. They are easy to use and worry free. You don’t ever have to worry about leaving the charger on the battery for too long. In fact, it’s best if you DO leave it on. When a battery is not at a fully charged state, sulfate crystal build on the plates and this robs you of power. If you leave your powersports in the shed during off-season or for vacations, please connect the battery to a 3 stage charger. This will ensure that your battery will be ready to start whenever you are.
Does over-discharging damage batteries?
Over-discharging is a problem which originates from insufficient battery capacity causing the batteries to be overworked. Discharges deeper than 50% (in reality well below 12.0 Volts or 1.200 Specific Gravity) significantly shorten the Cycle Life of a battery without increasing the usable depth of cycle. Infrequent or inadequate recharging can also cause over discharging symptoms called SULFATION. Despite that charging equipment is regulating back properly, over discharging symptoms are displayed as loss of battery capacity and lower than normal specific gravity. Sulfate occurs when sulfur from the electrolyte combines with the lead on the plates and forms lead-sulfate. Once this condition becomes occurs, marine battery chargers will not remove the hardened sulfate. Sulfate can usually be removed by a proper desulfation or equalization charge with external manual battery chargers. To accomplish this task, the flooded plate batteries must be charged at 6 to 10 amps. at 2.4 to 2.5 volts per cell until all cells are gassing freely and their specific gravity returns to their full charge concentration. Sealed AGM batteries should be brought to 2.35 volts per cell and then discharged to 1.75 volts per cell and then this process must be repeated until the capacity returns to the battery. Gel batteries may not recover. In most cases, the battery may be returned to complete its service life.CHARGING Alternators and float battery chargers including regulated photo voltaic chargers have automatic controls which taper the charge rate as the batteries come up in charge. It should be noted that a decrease to a few amperes while charging does not mean that the batteries have been fully charged. Battery chargers are of three types. There is the manual type, the trickle type, and the automatic switcher type.
What are primary and secondary batteries?
البطاريات الأساسية هي بطاريات جافة عادية ، يمكن استخدامها مرة واحدة فقط. البطاريات الثانوية تسمى أيضًا البطاريات القابلة لإعادة الشحن ، ويمكن شحنها وتفريغها للعديد من الوقت. بطارياتنا هي بطاريات ثانوية.
What is battery rating?
The most common battery rating is the AMP-HOUR RATING. This is a unit of measurement for battery capacity, obtained by multiplying a current flow in amperes by the time in hours of discharge. (Example: A battery which delivers 5 amperes for 20 hours delivers 5 amperes times 20 hours, or 100 ampere-hours.)Manufacturers use different discharge periods to yield an different Amp-Hr. Rating for the same capacity batteries, therefore, the Amp-Hr. Rating has little significance unless qualified by the number of hours the battery is discharged. For this reason Amp-Hour Ratings are only a general method of evaluating a battery’s capacity for selection purposes. The quality of internal components and technical construction within the battery will generate different desired characteristics without effecting its Amp-Hour Rating. For instance, there are 150 Amp-Hour batteries that will not support an electrical load overnight and if called upon to do so repetitively, will fail early in their life. Conversely, there are 150 Amp-Hour batteries that will operate an electrical load for several days before needing recharging and will do so for years. The following ratings must be examined in order to evaluate and select the proper battery for a specific application: COLD CRANKING AMPERAGE and RESERVE CAPACITY are ratings used by the industry to simplify battery selection.
What does the Reserve Capacity rating mean and how does it apply to cycle?
Reserve capacity is the number of minutes a battery can maintain a useful voltage under a 25 ampere discharge. The higher the minute rating, the greater the battery’s ability to run lights, pumps, inverters, and electronics for a longer period before recharging is necessary. The 25 Amp. Reserve Capacity Rating is more realistic than Amp-Hour or CCA as a measurement of capacity for deep cycle service. Batteries promoted on their high Cold Cranking Ratings are easy and inexpensive to build. The market is flooded with them, however their Reserve Capacity, Cycle Life (the number of discharges and charges the battery can deliver) and Service life are poor. Reserve Capacity is difficult and costly to engineer into a battery and requires higher quality cell materials.
What is discharge efficiency?
تشير كفاءة التفريغ إلى نسبة الطاقة الفعلية إلى السعة الاسمية عند تفريغ البطارية عند جهد النهاية في ظروف تفريغ معينة. يتأثر بشكل أساسي بعوامل مثل معدل التفريغ ودرجة الحرارة البيئية والمقاومة الداخلية. بشكل عام ، كلما زاد معدل التفريغ ، انخفضت كفاءة التفريغ ؛ كلما انخفضت درجة الحرارة ، انخفضت كفاءة التفريغ.
