Introduction to gel battery repair

1) Charging method: Generally, gel batteries with lighter vulcanization can be restored by normal charging. Generally speaking, the greater the discharge current, the shorter the battery life; the deeper the depth of discharge, the shorter the battery life. In theory, the gel battery should be used to prevent deep discharge as much as possible, and should be shallow discharge and frequent charging. (2) Hydrotherapy: charge and discharge the gel battery with heavier vulcanization. 1) Distilled water with the capacity of 500 ml drip bottle for hospital instillation is mixed with 0.5 ml analytically pure concentrated sulfuric acid to prepare a diluted sulfuric acid electrolyte with a density of about 1.050 as water supplement. 2) Pry open the upper cover of the battery (must be careful to avoid damage), unscrew the single control valve (or take off the rubber cover), add 5ml-15ml of self-prepared electrolyte to the battery, after injecting the electrolyte It is best to leave the battery for more than 10 hours, so that the replenishing liquid soaks into the separator to just see the flowing electrolyte (the flashlight is irradiated vertically to see the hole more clearly) or turn the battery 90 degrees so that the small hole faces Side, so that the excess electrolyte overflows, and then flip it back). 3) Connect the battery to the tester, and press the battery repair function button of the tester to repair. The tester automatically enters the desulfurization repair for three or six hours. After three hours of desulfurization time, it will automatically switch to work mode 3. Both charging and discharging, the charging current is 3A, and the discharging current is 5A. The tester automatically displays the discharge capacity and time, which is very intuitive . Record the capacity each time, repeat three or four times until the capacity no longer rises. (3) Battery parallel shunt method: If the battery temperature rises quickly during the repair process, the charging and discharging current should be reduced. At this time, two batteries can be connected in parallel and connected to a tester circuit, and the charging and discharging current is the original 1 /2 (ignoring the difference in internal resistance), the effect is also very good. (4) Battery series repair method: This method is used when the nominal voltage of a single battery is lower than 12V. For example, rechargeable emergency lights on the market often use 6V4AH and 6V7AH batteries, and the single output of the tester is 12V.
