RE: battery question
Chuck, The readings depend on the charger. Not all chargers are accurate. Nicads, like NiMH batteries don't reach their potential until 4 or 5 cycles. Put the battery on a slow charge, very slow and let charge for 24 hours. Then connect the battery to a Expanded scale voltmeter with a load, leave connect for 3 to 5 minutes and check the voltage. If the voltage drops below 1 voltage per cell, then the battery is bad.
Like I said before, some chargers don't give accurate readings when discharging.
Maybe someone else can add more information here.
