NO!!!!!!!! Blaze said 0.2amps but it really puts out (read output!!) 2200mah or 2.2amps. continuous. (It's not gonna stop even when the battery is full and can't take anymore ???) So a 100amp battery will take just under 2 days not 20 . Hope you like fireworks

p.s It's not likely that you could drain a 100amp battery low enough that you could put 100amps back in.(I know it was just a hypathetical size) If you drained it that much just throw it away and buy a new one cause it's going to be stuffed.
