How to solve the problem of sulfate?
TORCHN answers for you:
1、Hydrotherapy: After the battery is charged, discharge it for 10 hours or 20 hours until the voltage of the single-cell battery drops to 1.8 V. Then pour out the electrolyte in the battery and add distilled water immediately. Let it stand for 2 hours before using it. The current reduced by 20% from the above discharge current value continues to charge until the electrolyte begins to boil, and the density of the electrolyte no longer increases, that is, charging stops.
2、Activated charging method (equilibrium charging): That is, after the normal charging is completed, the battery is allowed to stand for about 2 hours, and then the charging current in the second stage of the initial charging is used for continuous charging. When the electrolyte generates a lot of bubbles, stop charging and let it stand for 2 hours, and then charge it according to the above method. This is repeated 2 to 3 times until the electrolyte has a lot of bubbles within about 10 minutes.
