lead-acid battery

Lead acid battery overview
what is the acid in battery？
Lead acid battery (VRLA) is a type of battery with electrodes mainly made of lead and its oxides, and electric ions are transferred through sulfuric acid solution. When the battery discharges, the main component of the positive pole of the lead-acid battery is Lead dioxide, and the main component of the negative pole is lead; When the battery is charged, the main component of positive and negative electrodes is Lead(II) sulfate.

Types of lead-acid batteries
The sulfuric acid solution of lead-acid batteries is generally stored in many compartments. The standard voltage of a single compartment of lead-acid batteries is 2.0V, which can discharge to 1.5V and charge to 2.4V; In applications, six single cell lead-acid batteries are often connected in series to form a nominal 12V lead-acid battery. We often see 6V lead acid battery,12 volt lead acid battery, 24V lead acid battery, 36V lead acid battery, etc., which are composed of 3 cells, 6 cells, 12 cells, and 18 cells, respectively.

AGM Lead–acid battery

Valve regulated sealed lead-acid battery (AGM Lead–acid battery)
This is commonly referred to as VRLA batteries. This kind of battery was first born in Europe in the 1970s. Compared with the previous Lead–acid battery, it has many advantages and is very popular with users. It is often used in UPS, telecommunications equipment, mobile communication equipment, computers, motorcycles, etc. This is because VRLA batteries are fully sealed, will not leak sulfuric acid, and will not appear acid mist when charging and discharging like the previous Lead–acid battery, so they will not corrode equipment and pollute the environment. Therefore, people call VRLA batteries as sealed (sealed) Lead–acid battery from the structural characteristics. In order to distinguish, the former Lead–acid battery is called an open Lead–acid battery. From the perspective of structure, VRLA battery is not only fully sealed, but also has a valve that can control the gas pressure inside the battery, so the full name of VRLA Lead–acid battery is "valve regulated sealed Lead–acid battery"

GEL battery vs lead acid

GEL battery, also known as colloidal sealed lead batteries, have an electrolyte composed of silica sol and sulfuric acid. The concentration of sulfuric acid solution is lower than that of AGM type batteries, typically ranging from 1.26 to 1.28g/cm3. The amount of electrolyte is 20% more than that of AGM batteries, which is equivalent to a rich liquid battery. This electrolyte exists in a colloidal state and is filled in the diaphragm and between the positive and negative poles. The sulfuric acid electrolyte is surrounded by gel and will not leak out.

Designed floating service life: 5 years @ 20 °C/68 °F up to 28Ah, 12 years @ 20 °C/68 °F for 28Ah to 250Ah

Valve regulated lead acid battery (AGM Lead–acid battery) VS gel battery

GEL gel battery has no free electrolyte after the electrolyte gel, so the probability of acid leakage is much smaller than that of valve regulated lead acid battery; Its infusion volume is 10-15% more than that of dilute sulfuric acid, with less water loss, so the colloidal battery will not fail due to water loss; The injection of colloid increases the strength of the separator, protects the electrode plate, and compensates for the defect that the separator will shrink when it touches sulfuric acid, making the assembly pressure not significantly reduced, which can effectively extend the service life of the battery; The colloid fills the gap between the separator and the electrode plate, reducing the internal resistance of the gel battery, and thus improving its charging acceptance ability. So the over discharge, recovery ability, and low-temperature charging and discharging performance of gel batteries are superior to those of valve regulated lead acid batteries; The consistency of gel batteries is better than that of similar AGM batteries.

The normal operating temperature range of lead-acid batteries is between -20 ° C and 60 ° C, so they can be widely used in solar power generation, wind power generation, automobiles, electric vehicles, communication, storage power, and other fields. Among them, automotive starting power is its main application direction.

lead acid battery maintenance

How to achieve the correct lead acid battery care? Roughly, the following 7 points need to be achieved.
Lead acid batteries require regular inspection after a period of use. For example, checking the appearance of lead-acid batteries for abnormalities, and measuring whether the voltage of the battery is average. If there is no power outage for a long time, the battery will remain in a charged state, which will decrease its activity. Therefore, even if there is no power outage, the lead-acid battery UPS must undergo regular discharge tests to ensure that the lead-acid battery remains active.

Use an original charger. Generally, the manual of a legitimate brand of lead-acid battery will provide detailed charger protection methods. If you are using lead-acid batteries, lead-acid battery UPS, or lead-acid battery portable power stations, it is necessary to confirm the best usage method and charger protection method in a timely manner before using lead-acid batteries. For example, if a 12 volt sealed lead acid battery needs to be charged with a 12V lead acid battery charger.

Ordinary Lead–acid battery shall be regularly added with distilled water. Dry charged batteries should be properly charged before use. AGM Lead–acid battery and gel battery are sealed, so these details need not be paid attention to.

Do not place lead-acid batteries near heat sources (such as transformers). Placing lead-acid batteries near heat sources can easily cause overheating, leakage, combustion, or rupture of the batteries.

Lead acid batteries are the most important part of electric vehicles, so it is important to protect the batteries so that electric vehicles can ride further. Do not replace the lead-acid battery charger casually. If the user's journey is relatively long, multiple backup batteries need to be equipped for lead-acid batteries.

Persist in charging lead-acid batteries every day. Charging lead-acid every day can keep the battery in a shallow cycling state, which will prolong its service life. Because the memory of Lead–acid battery is weak, the life of lead-acid battery will be greatly affected when it is fully discharged. So after the battery is fully charged, it is best to continue floating charging as much as possible, which has many benefits in suppressing the sulfurization of lead-acid batteries.

Charge the lead-acid battery promptly（lead acid solar battery can charged by solar panels） after each use. After discharging, the Lead–acid battery will begin the vulcanization process. After discharging for more than 12 hours, the lead-acid battery will appear obvious vulcanization. Therefore, after using the lead-acid battery, it is necessary to charge it in a timely manner to remove the slight sulfide crystals in the lead-acid battery, thereby increasing its service life. If the lead-acid battery is not charged in a timely manner after running out of electricity, these sulfide crystals will continue to aggregate and gradually form large crystals, leading to the failure of the electrolyte of the lead-acid battery. The battery capacity will significantly decrease, ultimately leading to a shortened battery life.
