Not sure, Nicads don't last if stored either. However, the non self
discharging cells have been around for a good decade now as far as I know.
What annoys me is the naff batteries they put into shavers these days. If
you get 18 months out of one then you are doing well, and in the old ones
you could remove the old ones as a pack, and get a new set, most nowadays
seem to suggest you break the shaver to remove the batteries to recycle then
buy a new Shaver, you listening Remington?

Clearing out the shed I came across my old 4.8v Challenge Extreme powered

I accidently touched the trigger and was amazed when the motor turned. I
though it might be the dregs of a charge in the cells, but I tried again
and it turned. In fact, it was not possible to stop it turning by
gripping the shaft.

I have no idea what brand NiMH cells were used in this cheap screwdriver
(Argos), but for the four of them to retain a good charge for 6 years
seems very unusual to me.

Probably Nicd then
