1. Open the battery cover and take off 6 safety helmets.
2. 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, we eat hot pot, why will eat more salty, that is, when the water evaporates, the salt will not evaporate through the water steam, the same reason, the acid in the battery will not be evaporated, the missing is water, so we just add about 20-30ml of distilled water in each hole.
3. After filling up, let the battery rest for half an hour, so that the sponge body around the plate fully absorbs water. Then use resistance discharge, put the battery in the electricity, all put out, no resistance, you can use a 12v bulb instead, such as: motorcycle headlights, car turn signals can be used, as long as it can discharge to 0v. How to judge the battery is close to no electricity, cement resistance discharge at the beginning of the resistance body hot, slowly gradually not hot, then the battery is out of power. The light bulb, but also directly, 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 first ride the battery to no power and then maintenance, which can shorten the discharge time.

4, after the end of the discharge to charge the battery, conditions can be used pulse charging, because the pulse charging method can effectively remove the vulcanization of the plate, improve the capacity of the battery. What you don't have can be replaced with a car.
5, after the charging is completed, use the syringe to draw out the excess water in each hole. A total of six holes, step by step to complete.
6, cover the cap and cover, you can load the car.
The second: When the battery capacity is not less than 50%, you can add a repair solution.
Third: When the battery capacity is less than 30%, the battery enters a scrapped state and needs to be replaced with a new battery.
Fourth: The use of distilled water can solve part of the problem of power loss.
The fifth: Use a high-power charger to charge and increase the capacity of the battery.
1, you can try to repair the charging method

It is to repair the battery with a pulse repair device first, remove the sulfide crystal, so that there is a chance to reactivate the battery that cannot be charged. However, with this method, it is generally necessary to continue to operate for 2 to 3 days, and the time is controlled within 1 hour per day.

2. Regroup

Then check to see if a single small battery is faulty. If a single small battery in the battery pack fails, the whole battery will not operate normally. In the case of a 48V battery, it is composed of four 12V small batteries, if one of the 12V small batteries fails, the entire battery pack does not need to be replaced, but can be reconfigured to solve the problem. Simply put, replace the bad 12V small battery with a normal 12V small battery. However, it should be noted here that we must pay attention to the matching of new and old batteries.

3. Charger with repair function can be selected

Since this type of charger has a repair function, it can be used to charge the battery, in general, charging for 8 hours also has the chance to reactivate the battery that cannot be charged. However, it is important to note that you must match the battery and charger model.

In short, if the battery is broken, it does not necessarily have to be replaced with a new battery, but the above three activation methods can be used to try. As long as one solution can be solved, the battery can be reactivated for use. However, in general, the reactivated battery performance can only recover to about 70% at most. Therefore, it is also important to develop good habits of use.
1. Unscrew the battery with a screwdriver and remove the battery cover
2. Fill the six screw holes with a syringe
3. Wait for the battery to rest for half an hour, use a wire to connect the positive and negative terminals of the battery and a 12-volt bulb in series to discharge the battery
4. Use the pulse charger to reverse connect the positive and negative terminals of the battery to charge the battery
5. After it is full, use the syringe to absorb the excess water in the six screw holes, then cover the battery cover, screw on the screw, and you can continue to use
