What are the charging steps for lead-acid batteries?

Lead-acid battery charging steps 1. Wipe clean, charge the battery and the electrode column head, unscrew the filling hole cover, and open the vent. 2. Slowly add electrolyte with a specific gravity of 1.28 into the battery, and the height of the liquid level should be 10-15 mm higher than the electrode plate. 3. The lead-acid battery after the electrolyte is injected, let the electrolyte soak into the electrode plate for 6 hours. 4. Charging is carried out in two stages: the first stage. The charging current is 7-8% of the capacity I, and the lead-acid battery voltage rises to 2.4 volts, and the bubble starts to appear for 26-30 hours. In the second stage, the charging current is half of the stage, and the charging time is 22 to 30 hours. After the charging is completed, the voltage of the unipolar lead-acid battery is found to be 2.5 to 2.75 volts. The battery will boil within 2 to 3 hours of charging, and the voltage and the specific gravity of the electrolyte are maintained. constant. 5. After charging, perform 2-3 charge and discharge treatments. When discharging the resistor, the discharge battery is 10% of the capacitor basin. When the discharge voltage drops to 1.7 volts, it is charged according to the above charging method. Repeat this to make the capacity reach more than 80%. 6. At the end of charging, adjust the specific gravity of each cell to make it equal. If the liquid level drops, replenish the electrolyte to the specified height. During charging, if the temperature exceeds 45°C, the charging current should be reduced, and the charging should be suspended when the temperature continues to rise above 55°C. Wait until the Ju degree drops below 3590 before charging. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
