Figure 5 : Chemical Action During Charging. As a lead-acid battery charge nears completion, hydrogen (H 2) gas is liberated at the negative plate, and oxygen (O 2) gas is liberated at the positive plate.This action occurs since the charging current is usually greater than the current necessary to reduce the remaining amount of lead sulfate on the plates.
The reaction principle of lead-acid battery remains unchanged for over 150 years from the invention.
