Garage storage of small battery powered items - help required please

[Once A Hero]

My garage is uninsulated and unheated apart from the electric and oil heaters I turn on when I'm in there for prolonged periods (which is not very often these days), so is cold throughout the winter months.

I have several battery powered tools/gadgets which more often than not will be dead as a Dodo when I come to use them.
I'm only talking, luggage weighing scales, digital callipers, remote controls - just small items that use small button or AA batteries.

I'm wondering if there is a device I can keep all these things in that would keep the batteries suitably warm, i.e. room temperature 20-21deg c or similar, but still be stored in the garage which is where they are most typically used.

A small plug in 'warm box' would do the trick, like a travel cool box, but warm not cool.

Does anyone know of such a thing or solution to this annoying problem?

I've done this before. Works well

how much does it cost to replace the batteries?
how much would it cost to heat them?

seems a pointless exercise to me. if you are really bothered, bring them in the house, otherwise, just expect them to be flat.

Go to a fruit & Veg shop or wholesaler and ask for a Polystyrene 4.5Kg Iced Broccoi box.

Not as first world as posting a pointless first world remark.

We had an issue in a remote shed, and used an old chest freezer with a greenhouse heater.

I'm just asking if there is a solution out there for this kind of issue. It's not so much about cost, it's convenience. Plenty of things plugged in in the garage costing me money already.

The simplest thing for me to do would be to keep them in the house, and take them out with me each time, but I can already see that will be me going out, forgetting them, coming back in to get them, then coming back in without them, going back out to get them and coming back in again etc etc

Hadn't considered that as not my area of interest.
I've got a colleague who's in to reptile keeping so he may have some old kit going spare

if you are going down that route, look at a small propagator for plants. usually much cheaper and a lower temperature to limit fire risk.

sorry for poo pooing your idea.
