Winter Battery Maintenance

I always keep mine on the tender when not in use. This battery is going on 12 years with zero issues. For about $40, you cannot beat a battery tender.

Physically remove in fall, store in my basement during winter months, charge 1 time per month, then reinstall in spring time. Done this for 25+ years and never had battery problems.

I always bring it in for the winter. It stays in the basement and I used to put a trickle charger on for a couple of days every month. I now have an inexpensive battery maintainer and it stays connected all the time. I keep a battery maintainer connected to the generator battery too. It stays in the garage, because the battery is a pita to remove and because I want it ready to go if I need it.

Yeah, provided you can park your trailer at home. Mine is 15 miles away in a storage yard. I bring them in, put them under the workbench in the basement and charge them a few times over the winter. Works for me but I would rather just plug the trailer in and watch them as others do.

The most important thing in winter battery storage is to keep it warm, and/or keep it charged. A discharged battery will freeze and burst the case, but a fully charged battery will not freeze. So all the suggestions so far are good.

Thanks Everyone! You've helped.

I recently purchased a solar battery charger/minder. I hope it will keep the battery topped off. It has a regulator that goes to trickle charge when the battery is at capacity and something to prevent the battery from discharging at night. Like I said this was a recent purchase so I don't know if it works as advertised yet. The lights work though!;)

ditto!

This is what I do also, along with my other vehicles that have batteries, like the lawn mower snowmobiles ect. I got tired of replacing the batteries in them every 24 months.

I leave the battery on the trailer. We keep the trailer plugged in all the time. So around once each month, I turn the disconnect switch on for a few hours.
