Failed NIMH Batteries?

RE: Failed NIMH Batteries?
The "failed" batteries are probably just so deeply discharged that their voltage is below the threshold for detection by the charger. One thing you can do is to very briefly (~20 seconds) connect a failed battery to a charged one, with positive (+) to positive, and negative to negative, so that the good battery charges the failed battery. Immediately afterward, place the failed battery into your charger, and it should be detected and start charging.
I don't know how this procedure affects the condition of either battery, but I have done this with batteries in a 6 cell LED closet light for at least two years, and the batteries still seem to be effective.
Be careful not to go on too long with the situation that resulted in the deeply discharged batteries. At some point, they will get a reverse polarity, and that is definitely not good for a battery.
