What happens if you overcharge a lead acid battery?
Overcharging Lead Acid batteries will damage them and can cause Hydrogen and Oxygen gas to form, leading to an explosion risk. You should never, under any circumstances, provide a voltage higher than the rated peak voltage! A charging curve limits the current into the battery until the voltage rises to the peak battery voltage.
What is the peak voltage of a lead acid battery?
Then, the voltage is limited to the peak voltage until the current drops (to 3-5% of the C rate for lead acid batteries). Standard "12V" Lead-acid batteries are six cells; the peak charge voltage is between 13.8 and 14.7V (at 25C, this value is temperature dependent); however prolonged time at this voltage will cause damage.
