I changed the charger mode to the regular nimh2 mode and set it to one amp. I did not have the guts to set it to a nicad mode - sorry
After about 10 times through the charger, it is now charging for 31 minutes and finishes with 7.51 V, 521 mAh, 1877 seconds, 13833 j. This is after I run the car down to a little faster than crawling speed. It seems to be getting better somewhat.
Should I just keep going with it?
