What happens when a car battery gets too low | Batteries Plus
Providing your battery with too much charge can be just as harmful as providing it with too little. When you overcharge a battery, the excessive current heats the battery and cooks the components inside. This can cause corrosion to form on the battery''s terminals, which makes your battery far less effective.
