I really want to like this 0 level spell, but it has some REALLY specific limitations. It seems like if you can only transfer charge between 2 of the same object, then what is the benefit of using this spell over just taking the other battery with you? You can't even use it as a universal battery charging adaptor, since a generator tap wouldn't be the same object as your battery.
So far the only use I can come up with, is the overcharge damage could be used to sabotage a supply of batteries, by using one of your own to overload the others.
I am hoping you good people can give me some more creative, but still legal uses of this spell.
Thanks!
