charging a battery and all about that
we tested battterys and first we had to charge
them because Mr G drained the battery power from
the batterys.when the battery has power the
energy is called stored chemical energy. then
when you connect it to something that needs
power like a light the power changes form again
and turns into electrial energy than when it
lights the light the energy turns into light
and heat energy.
