How long will a NiMH hold a charge if not used? If they completly
dischard, will they be harmed by recharging?
I read in the new popular science that someone came out with a 1 hour
recharger for NiMH.

| (...) That can happen - but the NiCd's are lower voltage (1.2 versus 1.5) - so no all battery operated devices are happy with them. Also, NiCd's have to be treated carefully and 'deep-discharged' or else they succumb to the 'memory effect' which (...) (24 years ago, 15-Apr-01, to lugnet.robotics)
