I think I'd like to charge slowly with the .3 amps but how do I know when its done?
Unlike my hobbico field charger which when used for Nicads will/should shut down when it peaks. this setup will just keep pumping in the .3 amps till I shut it off...

For that matter, I think my Car battery charger at 2 amps will also just keep pumping in the juice???

Sooo, I usually clamp my voltmeter probes onto the battery terminals with the charger clamps. I can see the increase in voltage as the charger is charging. when should I shut down the charger?

I admit, I wasnt very kind to my previous battery. I'll attempt to keep this one topped off.

Thanks

Steve

Edit: actually, perhaps I should get a better 12 volt charger as I started using a deep cycle marine battery on my canoe and I need to maintain that also?
