Ok so I've been reading and joining in on another thread about this which is just above or below this post titled -chargers what's the diff?- ( I should prob just be concentrating on one thread) so I should be looking at the watts the charger puts out/ charges at which will dictate the amps it will put out/charge the batt at according to battery size and at what speed it will charge? so , is this a major drawing point when choosing, so we are not waiting hours for batteries to charge? So they will all charge it's just a matter of how fast and how many?
