There are applications where NiMh won't work.
Like, any.
The NiCds in my shaver gave up and I tried replacing them with NiMh
cells, just running on the bench the charge lasted about 2.5x what the
user manual said for the original batteries - but under load of
actually shaving the batteries got pretty warm, indicating that not all
the rated 2400mAh was ending up in the motor.
I was getting about 5 shaves per charge with NiMh - new NiCd give
somewhere between 15 & 20 shaves.
FWIW, I'll never ever waste my money on NiMH's again. Oh, at first,
they're the bee's knees, but after only a few months of use, their shelf
life and usable charge deteriorate to a matter of a few seconds.
I guess you won't be using a cell phone, or just about any other
rechargeable device, then because they all use NiMH these days.
Try the Energizer Lithium 1.5V batteries; Mouser 525-L91BP-2 - size
AA at about $7 per pair (cheaper than in the store).
2900maH at 1.5V, no muss no cuss.
Yikes! The local Rite-Aid(r) has store-brand alkalines for like five
bucks a two-pack, and they outlast the "copper-top" ones by almost 2 to
1.
Cheers!
