Leisure battery storage over winter

[Dustydog]

The old girl now has a fully charged ex Kia Cee’d battery in her housing. The very expensive Numax Leisure battery is at home in the garage until March.
It rests on a thick piece of timber. Would I have damaged the Numax if I left it on the concrete floor?

I plan to use a smart charger every six weeks or so. Plus I intend to run some lights etc off the Numax just to “use” it.
Would you guys do anything different?

It's urban myth to suggest that putting batteries on a concrete floor harms them - but if the garage is unheated it will get cold which reduces it's capacity - it'll recover in spring though.

Using a smart charger every 4-6 weeks is a good idea

So far as I know, cold does batteries no harm. People seem to use them all the time in Alaska for example. We had a battery room in work. Placed away from everywhere. No heating, window always open.

.....flat lead acid batteries freeze in sub zero temperatures resulting in split casings.
No problem if kept charged.

Our AGM battery is in our conservatory which has no heating. It is in a box with styrofoam in the bottom. I charged it every 4 - 6 weeks.

Leaving a lead acid battery flat or close to is going to make it useless for much other than a door stop, it does not need being cold.

Best to keep LA batteries fully charged, winter and throughout the year. Mine I aim to keep on smart chargers.
