Have a couple brand new 2500 mah NIMHs. Have had them charging (initial charge) with a wall charger at 125mah for 30 hours and they are only showing 4.9v at the moment. Do they need to be left on much longer or need to be charged at a higher rate? Am I correct 250 mah for 15 hours be a correct charge rate. Btw they are 4.8 v batteries for a receiver pack.

Thanks for the help.
