Installed this yesterday and put in on charge , 13 hours later its still charging , I replaced a factory skeeter charger that only took maybe 8 hours at most to charge my batteries, reason I replaced it was I went to a 24 volt trolling motor. My question is how long should it stay red indicating its charging, my batteries should have been very close to being fully charged when I pluged up the new charger , charged them a few days before with the skeeter charger , which was two bank , and i went to three bank with the new cabela's charger, any help would be greatly appreciated.
