1. Charging method: Generally, batteries with lighter vulcanization can be restored through normal charging. Generally speaking, the larger the discharge current, the shorter the lifespan of the battery; The deeper the discharge depth, the shorter the battery life. In theory, deep discharge should be avoided as much as possible when using batteries, and shallow discharge and frequent charging should be achieved. However, overcharging some sulfurized batteries or using pulse chargers (such as Colin chargers) have good uses for restoring a certain capacity.

2. Hydrotherapy: For batteries with heavy vulcanization, hydrotherapy can be used to charge and discharge them in order to restore normal operation.

(1) Prepare a dilute sulfuric acid electrolyte with a density of approximately 1.050 using distilled water from a 500 milliliter drip bottle used in the hospital and 0.5 milliliters of analytical pure sulfuric acid as a supplement.

(2) Pry open the upper cover of the battery (care must be taken to avoid damage), unscrew the single cell control valve (or remove the rubber cover), and add 5ml -15ml of self prepared 1.050 electrolyte to the battery. After injecting the electrolyte, it is best to let the battery stand for more than 10 hours, so that the supplementary solution can penetrate into the partition until a flowing electrolyte can be seen (using a flashlight to vertically illuminate the hole for better visibility), or flip the battery 90 degrees, with the small hole facing the side, Allow excess electrolyte to overflow and then flip back.
