I understand that this 'downside' was true only (mostly?) of early NiMHs.

I've had a mobile phone ('cellphone' to USians) with the same batteries
for three or four years: it's only for occsional/emergency use, i.e.
mostly in glove-compartment or coat-pocket without being switched on for
incoming calls.

The need for recharge (when battery-state reaches a notch or two above
'empty') still only arises two or three times a year ...

That seems to be a common experience, and much better than nicads were (are?).
