But you’d have to do some ballpark calcs.

Of course. That’s the same reasoning behind putting battery capacity in Ah or mAh, assuming constant voltage throughout the battery’s life cycle. Correct?

The integral of v with repsect to time, gives a unit of v.s which is not a unit of energy. The thing that I was missing is the fact that constant current is assumed.

I used to work at a hobby shop, battery stuff for RC applications is the most misunderstood concept out there, even more so than how a 2-stroke glow engine works! hehe.

All the internals corrode over time, the battery internally ‘leaks’, etc. By cooling it, you slow that process.

By how much, at what temperatures and for what durations, I haven’t a clue, so who knows if it’s effective. I just know thats how I reasoned it, hahaha.

I have two mini fridges in my garage, one for beer, and one for batteries and chemicals (epoxies and resins mostly)

The quicker a Battery loses power the quicker it will end up in a land-fill.
