NiMH new battery conditioning
"William Sommer******"
Though it is possible to charge an eneloop battery in a
"Quick Charger", it is not recommended. We recommend
charging eneloop batteries in a NiMh charger that is [sic]
2 hours or more. Charging eneloop batteries in a "Quick
Charger" can reduce the overall life of the battery.
A two-hour charge is, by any reasonable standard, a "quick charge". It
would
be at least 0.5C -- hardly a slow charge.
** Standard charge for a NiMH is 16 hours at 0.1C.
Quick chargers deliver about 0.2C to 0.5 C
Fast chargers deliver 1C to 4C ( ouch ! )
Because NiMH ( AA, A or 9V ) cells vary widely in rated capacity - the same
charger has multiple rates.
So called " simple " chargers have a timer as the only cut out.
A 4C fast charger that only has a timer is a lethal weapon.
IME - the worst offenders in supplying chargers that are practically
guaranteed to ruin the cells are the battery makers - ie Energiser, Varta
and Sanyo.
Funny about that.
