Have the battery now been several weeks in tough conditions and am satisfied. Quick loaded, long consistent performance, then more rapidly performance degradation. Typical NiMH battery behavior precisely. Well made, no burrs, precisely, does not wobble and is not dependent upon removal. By the way, for all who do not already know. If a NiMH battery, no matter what, the first signs are to be empty, then please check the battery equal to recharge. Not quite suck the battery, otherwise the NiMH dies more quickly than one would like. The NiMH is like a race car, although peak power but also a veritable sensitive soul. And seen from improperly handling potential ago can not be compared with the DAC-resistant NiCd batteries.
