There's no way that a 500mA wall wart could ever deliver enough current

The important thing would be to check what the charging current actually
was (flat battery and full battery), and see if there was enough / not
too little to be of use / not too much so that it would kill the wall
wart.

I recently killed a battery by substituting an AC wall wart for the genuine
article. Another family member had shuffled the warts and I didn't spot it in
time. I now attempt to label all warts with their original use. It may save
other expensive mistakes.

A car battery?
