    50% Failure

    Overall: 1 out of 5

    My experience may not be typical, but out of the pair that I ordered one has an internal fault and will not charge properly (and I tried two different 'intelligent' chargers). So . . . now I have a relatively inexpensive purchase, but one that now must be recycled instead of used (ship a defective NiMH back for a refund or exchange? What could POSSIBLY go wrong?).

    I'm just sayin' . . . this points to poor quality control on the part of the manufacturer.

    Great batteries

    Overall: 5 out of 5

    These are some of the best batteries I have ever used. The fact that they don't self discharge allows me to use them in cameras, toothbrushes, flashlights and more. In fact since the end caps will accept solder I have replaced the batteries in a toothbrush, hair clippers and an electric shaver. In every case they work better than when new and the hair clippers can sit for long periods and be ready to go.

    Watch out on these!

    Overall: 2 out of 5

    AA positive terminal does not protrude the standard distance so that when these batteries are used in a flashlight, contact from battery to battery is questionable/sensitive/intermittent.
