Keep batteries on charge over winter?

[flyboy4533]

We have a 1997 Winnie Brave 31RQ. What is the best thing to do with the batteries over the winter? I have a Battery Tender installed and always connected to the vehicle's battery over the winter which seems to work out fine. In the past I've always kept the house batteries installed and on charge with the house's built-in battery charger/converter. I'm in northern NJ where the temp gets down to 15 - 20 degrees during the winter months. Just wondering what other RV owners are doing. Thanks

I guess I could argue that statement...not that it matters 🙂
I had a '57 Ford in storage that didn't get started and run but twice a year for the last 8 years. I never had a trickle charge or solar on it, and it always started for me. Finally a couple years ago it failed...took it to the AutoZone where I bought it and they couldn't believe it....it was 13 years old. They thought that it was a local record.

If battery tender has desulphation and a float function, it's perfect. We use a battery minder.

You need to determine whether your battery tender is intended for use in long term storage. Some are, some aren't.

I leave mine plugged in, but I have a temperature compensating 4 stage charger that I know won't overcharge my house batteries.

I have my starting batteries out of the truck right now on a float charger, but will put them back in soon (cleaning up the battery box) and just start it every so often during the winter.
