Trickle charging multiple batteries...

[lilskipp84]

Come winter, I'd imagine it's recommended to remove batteries from both 96 sea doo xps and keep on a trickle. Both batteries.are new this year. Any recommendations on a charger type, and what is the process to keep two trickled throughout the winter. Also have a 4 wheeler battery I'd like to aDD to the mix. Thinking swapping out each battery weekly on the trickle. Suggestions?

Battery tender jr. remove the batteries and store them in a place that stays above freezing, I store them in my garage. Do not keep them on a concrete floor, I have an old bookshelf, or at least keep them on a piece of wood. Trickle charge them overnight every 2-4 weeks. If you keep them on a constant charge you'll cook the batteries.

You do know we're still in Aug.

yea...just getting my ducks k
in a row....90 in philly tomo so ill b out in the water...so ur sayin tender each one for a night once every 2-4 weeks throughout the winter?

Needs to be wired in Parallel. Tender positive to battery positive, tender negative to the OTHER battery negative. Then take a jumper wire battery to battery that goes negative to negative and another wire positive to positive. This will allow equal current and amps to each battery and still charge one even if one is dead or shorted.

I read in one of my car magazines a while back that batteries should not discharge on concrete floors. Something to do with newer batteries having a better construction & no conductivity to the floor? I am surely not gong to test the theory tho. Not worth the risk. I have always kept all my batteries off the floor & still do. So I am with you on that one...

I also have a few cars that almost never move, & sadly don't get started much either. I have chargers like the JR on them 24/7 They hold up fantastic. months & years. Its those dang battery chargers that don't drop the voltage when they are charged that are so destructive.

But, I agree, no point in keeping a maintainer on a battery that is sitting that cant drain much anyway.

I won't argue, except these little batteries are a lot easier destroyed than the big honkers in our cars and boats.

Sure not looking to argue in anyway. I just know the good battery chargers will intelligently relieve their charge once its up to good voltage & won't charge until the voltage drops significantly.

I had some crap shumacher (spelling?) chargers that would never drop below 13 volts. they cooked the batteries away in a couple months. I wasn't happy. threw away the batteries & the chargers......

i'm going to second the overnighter, once a month sounds fair. do battery 1 on the 1st, battery 2 on the 2nd.

It's funny, I have a Neverstart battery in my atv, i run an aux stereo, lights, two winches, and a snow plow with electric turn. It's funny how that thing is 4 years old, sits in a cold shed all winter, and I've never had to charge it once. But yet the ski battery's seem to be so much weaker and that battery is smaller as well

i have a battery tender plus (smart charger) and left mine (agm) on all winter. great to have as i'm really bad at remembering to maintain my batteries manually.

I've got a NeverStart in the tractor, this is the seventh season, same thing, it seems to thrive from neglect.

For winter storage, I pull both my batteries (two ski's), place them on my wooden shelf, and about two weeks before the season I hook up my smart tender in parallel and let it do its thing. I have done this exact process for about 15 years now. I owned my Polaris skis for 11 years and installed two batteries in one and only 1 battery in the other. So for with my Seadoos, I am on season four and have OEM batteries.
