I have a battery charger that charges at a rate of either 2amp / 8amp / or 12 amp. my trollin motor battery is 875 ca / 675 cca. is it better to do a slow charge like the 2amp or a faster charge like the 12 amp setting? I have honestly out of habit just done the 12 amp setting, it works fine, just not sure if its better for the battery to charge it at a lower/slower rate. any advice would be great, thanks all, God bless.
