Can electric car battery be repaired? How to do that

Open the battery cover and remove the 6 helmets.

Fill each hole with distilled water with a syringe. If 1.28 standard electrolyte is added, the plate may burn out due to excessive acid dissolution. For example, when we eat hot pot, why do we feel more and more salty? That is to say, when the water evaporates, the salt will not evaporate through the water vapor. In the same way, the acid in the battery will not be evaporated. So we just join in each hole about 20-30 ml of distilled water.

After filling, let the battery rest for half an hour, so that the spongy body around the plate can fully absorb water. And then you discharge it with resistance, you put all the electricity in the battery, and if there is no resistance, you can replace it with a 12v light bulb, such as motorcycle headlights, car lights can, as long as you can have the effect of discharge to 0 v.How to judge whether a battery is nearly close to no electricity? Cement resistance discharge at the beginning of resistance body hot, slowly gradually not hot, then the battery is out of power. Bulb words, but also direct, as long as the light slowly does not light, it shows that the battery discharge is over, the discharge time depends on the capacity of the battery discharge. We can ride the battery out of power before maintenance, which can shorten the discharge time.

At the end of discharge, the battery can be charged by means of pulse charging, which can effectively remove the vulcanization of the electrode plate and improve the capacity of the battery. If you don't have one, you can use it instead.

After charging, use a syringe to draw out excess water from each hole. A total of 6 holes were completed step by step. Put the cap and lid on and load the car.

Battery is generally the production of vulcanization caused by the decline in capacity, the causes of vulcanization are: large current discharge for a long time, the form of loss of power, and long-term let the battery in the loss of power, water shortage and so on.

Actually there are many repair methods, your individual does not have professional repair equipment, only can add water to undertake maintaining.

Battery whether free maintenance of the dry battery or add water bottles of water and electricity needs to be maintained. Maintenance-free is not not maintenance-free at all, just not very often.

General battery repair is through the battery repair instrument and battery repair fluid to carry out. If you don't have these tools, you just add water for simple maintenance. Tap water and ground water and mineral water are not good, must use distilled water, deionized water or high purity water.

If the battery appearance is not damaged or swollen, and there is no sign of short circuit or break, the following methods can be adopted to try to repair the battery:

1, The battery is charged by depolarization in the way of positive and negative pulses, and then completely discharged for three cycles. If the capacity shows signs of recovery, it can be recycled for several more times to achieve better repair effect.

2, Add water repair must add deionized water or pure water, do not add tap water, otherwise it will cause self-discharge battery problems.

1, Completely discharge the battery, because the acid density inside the battery is basically less than 1.1g/ml after discharge.

2,Remove the cover plate and remove the safety valve. Be careful not to dirty the safety valve for later use.

3, Add water. Generally the amount of water added to a single cell of 12AH battery is 8 ~ 10g, and the amount of water added to a single cell of 20AH battery is about 15g.

4, Sit for about one hour, and install the safety valve and cover;

5,Recharged. After a full charge and then to completely discharge, so three cycles, capacity will be a good development.

when Lead- acid batteries not in use for a long time:

1, Before the use of the battery must be fully charged, and in full charge of the premise of the general recommendation in 2 to 3 months must be charged to the battery, the condition of the best 1 to 2 months to charge.

2,Electric cars should be stored in ventilated cool room when not in use, the load line disconnect after a full charge the battery pack, the sulfuric acid salinization due to lead-acid battery itself , if long time don't add electricity capacity recovery is difficult to make impact longevity. Therefore, it is generally recommended that you must recharge the battery in 2-3 months to facilitate the battery life.
