Why AC Can’t be Stored in Batteries like DC?
We cannot store AC in batteries because AC changes their polarity up to 50 (When frequency = 50 Hz) or 60 (When frequency = 60 Hz) times in a second. Therefore the battery terminals keep changing i.e. Positive (+ve) becomes Negative (-Ve) and vice versa, but the battery cannot change their terminals with the same speed so that’s why we can’t store AC in Batteries.

In addition, when we connect a battery with AC Supply, then it will charge during positive half cycle and discharge during negative half cycle, because the Positive (+ve) half cycle cancels the Negative (-Ve) half cycle, so the average voltage or current in a complete cycle is Zero. So there is no chance to store AC in the Batteries.
