Cold weather and batteries. Pull them inside?

[Jimbee]

Hey All,

Just curious how many of you bring your battery(s) in during the cold weather months vs leaving them on the camper. Last few years I've left them on the camper and plugged into the house. Hasn't seemed to affect them in the least when I'm dry camping. Am I just lucky or is keeping them hooked up and plugged in the right thing to do?

Thanks

CORRECT ! Actually better than leaving them on a "maintainer" continuously.

Watch the water levels though. I've been bringing mine into the garage for years and placing them on a trickle charger then about every couple of months I equalize them. So I am interested in this post, looks like I am guilty of overkill --- again.

I take mine in my insulated/heated garage during extreme months, and give a maintenance charge when needed. I have a smart converter, so really could just leave on board, with no issue. I am plugged in at home 24/7 most of the year, when not using. I just see no need to keep other small battery drain items going all Winter, that cannot be disconnected.

If you are plugged in and charge system is working... your battery is fine in all conditions.

Other than performance, cold is good for a battery. A fully charged lead-acid battery freezes around -90F. Cold temperature reduces self discharge. Fully charged and disconnected from all loads they will probably be fine over the winter even with no charging.

I rotate a small NOCO charger through all of my unused equipment during the winter to ensure it stays topped up. I just move it to the next battery on Sunday evenings.

The factory converter may result in water use during prolonged charging, so sure to check the cells occasionally if you rely on it.
