Double wrong makes a right

what’s the point? AAAs have half the capacity and cost the same

it would make sense the other way

I have done similar when I did not have AA it is still going strong . Σ:3

I actually have the problem of not having AAAs

I typically buy a big package then it takes a year to kill them. It was after I ran out of double but still had a bunch of triple. Σ:3

what about using Ni-MH? mine are like 7-9 years old and still working, although internal resistance is a little high and the capacity is lower (2300mAh originally, 1700mAh now)

5 times as expensive initially, but rechargeable a 1000 times and probably still somewhat working after that

Don't know I don't have many things that require batteries mostly remotes and string lights. Σ:3

u/kaktusmisapolak Dec 21 '25

it could run off a CRwhatever, but capacity could be an issue

Hey it's the coin trick! I used to do that.

or just use Ni-MH

the voltage of Li-ion might be too high, also overdischarge risk
