Question

process in charging method of lead acid battery? ​

Answer 1

Answer:At cathode

PbSO4 + 2e- => Pb + SO42-

At anode

PbSO4 + 2H2O => PbO2 + SO42- + 4H- + 2e-

Combining above two equation, the overall chemical reaction will be

2PbSO4 + 2H2O => PbO2 + Pb + 2H2SO4

Explanation:

Answer 2

The Lead Acid Battery uses the constant current constant voltage charge method . A regulated current raises the terminal voltage until the upper charge voltage limit is reached, at which point the current drops due to saturation. The charge time is 12-16 hours and up to 36-48 for large stationary batteries.
