That must be a sophisticated charger if it can spot the slight differences
between nicad and NiMH, and reject the latter.

It looks like all discrete circuitry, but its SMD which makes it a PITA to
trace.


Although some shavers have a "quick charge" mechanism to handle
"emergencies", I suspect most are little more than trickle chargers.

AFAIK it has one fixed charge rate, it goes into burst mode as the cells get
nearly full.

According to the user manual it isn't supposed to operate from the wall wart
when the battery is flat, but it came with a SMPSU adapter instead of the
iron-cored wasll wart as advertised - this does allow plug in and use when
the battery is flat.


Suggestion... Try running down the NiMH cells (to 1.1V or so) before
putting
them in the shaver. NiMHs generally have a higher full-charge voltage, and
the charger might be "objecting" to that.

The odd thing is, while the motor runs OK with NiMh cells it cuts out if the
charger is plugged in - that doesn't happen with NiMh cells fitted.


The battery failure might also be Nature's way of reminding you that
shaving
is unnatural, an affront to one's manhood that should be abandoned
post-haste.

You calling me infidel or something?!
