We cannot store AC in batteries because AC changes its polarity upto 50 (When frequency = 50 Hz) or 60 (When frequency = 60 Hz) times in a second. Therefore the battery terminals has to be changed with the same frequency in order to store the power but practically this doesn't happen.That’s why we can’t store AC in Batteries.
Also when we connect a battery with AC Supply, then It gets charged during positive half cycle and discharged during negative half cycle.Since the net stored charge during Positive (+ve) half cycle cancels the negative (-Ve) half cycle,the average voltage or current in a complete cycle is Zero.Hence it is not possible to store AC power in the Batteries.
Also note that Average Voltage x Average Current ≠ Average Power.
