Battery store energy which is produced by basically by chemical reaction. Due to chemical reaction positive and negative ions are liberated from electrodes are deposited using electrolyte.

So when external load is connected across the electrodes DC current will flow

I have a shop heater with a 1/3 hp capacitor start, induction motor driving the fan. Intermittently, the fan motor speeds up significantly for several seconds (15-60 sec) then slows to normal operating speed.
