Trickle charging during winter 12 v

I'm storing my new Rockwood 2514g pop up camper outdoors this year. It will be winterized and covered well, but I am taking home my battery and store it in the garage. I want to hook up a trickle charger. I saw a Black and Decker BM3B, 12 v charger / Maintainer. It basically performs trickle charge technology throughout the winter season..... Without you doing any thinking on maintenance for the battery during the off season. Since this is my first go round does this sound like the right choice? Thanks

Looks fine. One safety suggestion: Keep the maintainer 2 or more feet from the battery and anything flammable. I had a buddy have 2 maintainers fail and burn from voltage spikes in his utility power. Almost burned down his garage with cars and motorcycles in it.

Buy one of these. set it for 1 hour in any 24 hour period. plug your trickle charger into it.

You wont boil the battery and it will keep it topped off.

I used to remove my 2 Interstate marine/RV deep cycle batteries and leave them in parallel on an automatic trickle charger all winter in the garage. Never used any water and the batteries were still in excellent shape after 9 years.

Also, never set a battery on concrete, it will still discharge with the maintainer. keep it on a block of wood or a shelf.

I use battery tenders (brand name) year round. They are intelligent chargers so you won't overcharge and burn off electrolyte solution.

If you are using a maintainer / charger I would not put it on a timer. I know the one I have will go through a charge cycle when you first hook it up then it will go into a maintenance mode. If it is a good quality maintainer it should not boil your batteries.

A good maintainer should hold the battery at 12.7-13 volts. Much over 13.5 will lose electrolyte and affect battery life.

Agreed if you are using a maintainer then do not use a timer.


I use a multiple output maintainer in the boat. It's mounted inside the boat and keep the batteries charger all winter long. I just plug in the boat and don't have to think about it all winter long. My batteries are lasting longer than ever and I don't have to pull then from the boat as part of my winterizing program.

IMO Best of all of them. We put them on anywhere from 4 to 8 race cars and a couple ATV's and Golf Carts (pit vehicles) all winter long. Never came back to a bad battery.... They make a unit that charges 4 batteries at a time. We use those and a couple of the Battery Tender Jr.s

Four six volt and two twelve volt here. Battery tenders are cheap insurance against expensive replacement.

This used to be the case many many many years ago. Today's batteries being incased in a type of plastic has resolved this issue....as someone else mentioned...Urban Legend!

I use a Battery Tendr, same type that I use to keep my motorcycle and golf cart batteries charged over the winter. BTW my motorcycle battery is going on 10 years old and I think this year I'm going to change it because I know it's gone above and beyond its rated life.
