A battery is a fuel too. It is chemical energy. It converts chemical
energy to electricity.

It *stores* energy, if you're talking about a rechargeable type. A dry

Energy can't be created or destroyed, just converted from one form to
another.

And the efficiency of that conversion is all important.
