Good 300 mAH battery
Daniel Baechi (Switzerland) 3/3/2014 7:01 AM
Battery contains two cylindrical lithium cells and PCM which works reliably. Measurements showed 300-350 mAh capacity. One of five batteries arrived in deep discharged state, one only had 250 mAh capacity due to cell inbalance (premature charge termination).
happy with their service and products

Battery space is the only place I was able to locate the product I wanted-a rechargeable Lipo 9v. It's reasonably priced and they were willing to work with me to reduce the shipping. I'm very happy with their service.
