What happens if an AC voltage is applied to a battery?
A chemical battery is inherently DC, and must have a net DC to current to charge it. If the peaks vary too much from the average DC, then the battery can be damaged. Negative current will discharge instead of the charge the battery. Excessive current in either direction will damage it. $endgroup$ –
