    Trickle charging multiple batteries?

    I have 3 jetskis and 2 motorcycles. Is it possible to trickle charge them all using one charger over the winter connecting them in parallel? Is there any method which can be used to keep them all on the charger?

    What do you guys do?

    I trickle charge each battery (8 of them) for 8 hours once a month. I have a cycle that I follow to keep them all topped up.

    Re: Trickle charging multiple batteries?

    If you try to charge them all in parallel, you'll run the risk that one bad battery will force the charger to overcharge all the other batteries, trying to bring that one battery up. Happens a lot with electric golf carts, for example, and can ruin $800 in batteries.

    I do as BLRider outlined, except I charge each battery in my skis or bikes once every 2 months. I leave the battery disconnected from the machine when I store them; they seem to survive the winter with a much higher state of charge this way.

    Ha, I guess I will just line them up in a 'production line' and cycle moving the charger from one to the other throughout the winter. I might need to label each battery so that I remember where to put them back.

    All lined up - that's the way I do it. First day of the month the process starts each month.

    I use one charger as well and just rotate the batteries through a cycle. There are chargers you can purchase that accommodate 3-4 batteries at a time, but you'll be shelling out coin for something that does the same thing you already have, just a little extra work and attention on your part.
