Another member recently wrote of his BTY "1000 mAH" AAA batteries having a real capacity of only about 200 mAH.

I have just tested some new BTY AA "2500 mAH" NiMH batteries. They average 200-300 mAH actual capacity on my Maha C9000 charger. That is 1/12 to 1/8 of the stated capacity. A break-in would probably increase this but even a 100% increase would still leave these batteries in the pathetic category.

Stick to decent brands - Sanyo, Powerex , Energizer etc.
