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.

Having found a couple of good NiCds for the shaver, the foil split.

The spare shaver I bought and never used for about 3 years uses NiMh and
didn't hold a charge the next time I plugged the charger in the batteries
got hot.


I installed a mirror in the shower, and use those plastic throw-away
Bic razors. Warm, cozy, reliable way to shave.

I've got a Gillette M3power for special occasions, there's also 2 other
types of (no battery) gillette shavers in the old mug with no handle when I
CBA buying blade cartridges for them.

If I get really desperate I've got an old Philips rotary wired to a mini non
standard XT PSU, when I let my hair grow long it ends up in the cutters and
tangled round the drive pins, so today I did a DIY skinhead job.
