Now the battery according to the capacity to calculate, or to lead acid battery. Lead-acid battery has a great advantage in its capacity, which can not be replaced by other batteries at present. In addition, its high current discharge characteristics, also determines the advantages in starting batteries. But if the frequency of use or improper maintenance causes the battery capacity to decrease, then what can be done to fix it? Let's take a look!

How to repair the reduced capacity of lead-acid batteries

1. Add distilled water to repair. Electric car batteries are lead-acid lean batteries that can be repaired with a little distilled water. Generally 20AH battery, each hole plus within 10ml; 12AH battery, up to 6ml per well. Adding too much will not help and will cause the battery to fail.

Take replenishment repair, the purpose is to dilute the concentration of high sulfuric acid normal electrolytic reaction, open the battery cover, you can see six round holes, to each round hole injected a certain amount of distilled water, then soak for more than 24 hours.

2, cycle charging method repair. When charging, the battery can be overcharged for a while, and control the liquid temperature does not exceed 40°, and then discharge 30%, repeated several times can repair the battery capacity.

3, high voltage charging method repair. It can provide more current and increase the initial capacity of the battery. Eliminate the density of lead sulfate crystals caused by long service life or improper use. But the elimination of the high voltage causes the plate to soften so few people use this method.

Water repair repair can only use distilled water, can not add other types of water, because other water contains metal molecules, will lead to other reactions in the battery, the battery is easy to be damaged. To replenish the battery but also use a professional water refill tool - battery water gun, can avoid the problem of manual water control is not accurate, add too much water or insufficient will affect the battery characteristics of the balance and lead to the battery life is shortened.

Battery watering gun, can be a key to water, water full induction stop, can effectively ensure the consistency of the water level, there is no need to worry about the problem of uneven water. It can effectively improve the maintenance efficiency of water addition and ensure the consistency of battery unit characteristics after water addition and maintenance. Improve battery efficiency and service life.

There are many ways to repair lead-acid batteries, but if the above methods still cannot be solved, the battery may have been close to scrap, can be replaced with a new lead-acid battery to use, or find a professional maintenance personnel to repair.
