Nimh c and d cells

Just noticed amazon basics in C with 5000mah and D with 10000mah. Just need to think of something to use them in and a charger.

9V’s too, and the price looks good.

So are there any high performance c or d flashlights?

I got those for my ml50 and 4d maglite. Occasionally i use them in my magcharger with adventure sports drop in with good results

I hope those aren’t chinese rated mAh’s :wink:

I wonder what the on-the-shelf self-discharge rate is?

The AmazonBasics NiMH cells appear to be all made in China now. Not saying that’s necessarily bad, just possibly not the same as the made in Japan stuff from a couple of years ago. Has anyone tested the newer “China” ones to see how they perform?

I normally just use AA to C and 3xAA to D adapters, if needed.

Yeah, I’m using the latter in my 2×D LuxPro, just to burn down leftover alkaleaks.

Curious how those NiMH cells would work in there at 1.2V vs 1.5V. No worse than once the alkies are half-spent anyway, I imagine.

You should get more current flowing when using NiMH instead of alkalines, that is if your light can take it.

I have a camping mattress pump that runs on 4 D cells. 12 AA NiMH eneloops powers it nicely.

Yeah, I melted an emitter off its board on an old direct drive mag mod, by using NiMH instead of alkaline D cells. Oops.

Are there any particular brands of C and D NiMH batteries that folks recommend?

I saw the Amazon versions yesterday. Tenergy has some, EBL, etc…

I would like a set of four of each size for various devices, perhaps two sets if they hold their charges.

Thanks!

Not a lot of data on C and D. This guy has done some D reviews: Torchy the Battery Boy: NiMh D size Batteries

I’ve got some Tenergy Centura and Soshine C-cells. They work “OK”, they DO NOT come up to claimed specs, and capacity is dropping with use pretty steadily.

I have some OLD (10+ years) Radio Shack NiMh that have seen a LOT of use and they are still OK cells.
Some old Sanyo C (plain robin blue wrap) I got at an electronics store a long time ago for <$1 are still doing well, but only ~2000mAh when new.

Thanks for the link, flydiver!

Interesting that some of the batteries tested came out higher (though, not of a high capacity, for sure.)
