    Is it best to plug the charger in after every trip, even if out for only a few hours? Or is it better to run the batteries lower, then recharge?

    Never ever let a battery sit not fully charged.

    If you have an on board charger that charges and maintains a charge just leave it plugged in all the time. I have an 02 Ranger that is almost always plugged in when not in use and I have had great luck with batteries and no issues with the charger.

    I plug mine in after each use – no matter how much charge was used. Not sure if that is the best for the battery – Just want mine fully charged each time out – You never know how windy it is going to be or how long you may want to stay out. The last thing I’d want is for the trolling batteries to go dead when the fish are biting

    X2. Including the starting battery – especially if you are making a lot of short runs with the gas motor. Anything less than FULL charge leads to short battery life and frequent battery replacement.

    Thanks Guys. I have been plugging it in after each trip. I just wasn’t sure if the short charges were good for the batteries.

    The chemical reaction that creates the electric current leaves a residue of a chemical. The charging process reverses the reaction so that residue gets back in place. If there is any vibration (like from the 70+ trains past my house every day or bouncing down the lake), the residue settles to the bottom of the battery – never to produce electricity again. SO, recharge with a good charger that maintains that maintains without overcharging.

    Yep, plug her in after every use and leave it plugged in whenever you can.

    Eric, can you say that again? We are supposed to leave the charger plugged in whenever the boat is in the garage? It won’t hurt it to leave it plugged in?

    That depends on the charger. Some chargers will just keep cooking your battery so better to find out what you have first.

    I believe that unit is a fully automatic model – you should be able to plug it in and forget it. It should turn itself off after fully charged and even cycle back on if needed.

    “Automatic shut-off feature extends battery life by shutting down when charging is complete.” Straight from the link. Should be good to go……..I leave mine plugged in 24/7 on the lift or in the driveway.

    Yes wade, as long as the charger is operating properaly you can leave it plugged in at all times. Once the battery gets fully charged it will turn off. Once it drops to somewhere around 96% it will kick back on to maintain and also bring it back to at least 98%. Shouldnt have to worry about it cooking the batteries at all!!!
