Have a on board charger for my trolling motor batteries. After a very hard day of running on windy days it takes around 12 or 14 hours to fully charge. My question or concern is if they dont get charged fully before going out the next day will it hurt the battery life and is there a quicker or better way to fully charge them overnight. Thanks
Sounds like your on board charger is rated at 5 amps per bank....If you are running a 24 volt system and need to be ready the next day I would either purchase a higher amp on board or purchase 2 15 amp automatic chargers, hook one up to each battery then you'll be ready in morning.
Trolling motors are hard on batteries, going out with partially discharged batteries will certainly shorten the life of the batteries.... or worse not have enough capacity to fish all day..........
Short of putting them on a car charger, not a lot you can do....realistically. Just hook them up to your on board bank charger and the charge you get is the charge you have.....fish it....but that's just meQuote:

Deep cycle batteries need to be fully charged as quick as possible after use, failure to get them to full charge shorts the life span. If charge is not doing the job get a bigger charger or buy batteries sooner choices
