vinnybugs Posted August 3, 2020 Report Share Posted August 3, 2020 I have two deep cycle batteries for my trolling motor. Both r less than a year old. Stupid question is why does 1 battery fully charge faster than the other? I use a minkotta 2 bank charger. Shouldnt they charge almost same amount of time? Thanks Quote Link to comment Share on other sites More sharing options...
SCFD rtrd. Posted August 4, 2020 Report Share Posted August 4, 2020 Some chargers are designed that way. If the leads are labeled #1 and #2, usually #1 is designed for the starting battery and will put out more charging amps. The last two chargers I've installed were designed that way and stated so in the manual. Quote Link to comment Share on other sites More sharing options...
