Once upon a time I have purchased several Fujitsu NiMH AA cells. They are claimed to be HR-3UA, min. 2500 mAh capable, manufactured by FDK Corporation in Japan. Everything sounds good, right?
But at least one of them has "lost" its upper limit and an ability to store power: you may charge it indefinitely. Right now I have pulled this one out of Xtar VC4 charger while there was an indication of 3200+ mAh charged. It was noticeably warm, not even close to "hot". At the same time lights I used to put it in refused to operate very quickly. First I was inclined to blame the lights for their poorly made drivers with high parasitic drain, but then understood that this cannot be the reason — they are of different manufacturers and turned out to be OK with different other cells.
Is this enough to avoid this brand?
P.S.: An after all this super-puper overcharging Zebralight SC53Fc blinks only once, indicating that the cell is close to discharged state.
P.P.S.: Yeah, I know — I must find and check other Fujitsu cells. One is not a rule
