Sorry, chaps, this is really small fry for the DIY forum, but don't where else to ask...
I've got some rechargeable 9V PP3 NiMH batteries (200mAh) and have just discovered that my (rather ancient) battery charger (or at least the only one I have with the appropriate PP3 contacts) has a charging voltage of 7.2V. Is this is a problem, i.e., will the 7.2V charger charge 9V batteries? Should I allow extra time to compensate?
(I realise the charger is only 7.2V because it dates from the days before NiMH had even been thought of -- it's almost 30 years old! -- and was designed only for NiCd PP3s, which presumably only ran at 7.2V.)
