From memory its was a once off ...
The eneloops seem to be functioning just fine , one pair in a camera , the other two in AA lights , so far no other issues
Thanks ;)!
I have 2 - C9000's (1st bought on 12/2009) and haven't had any problems whatsoever [knock on wood 
]. IMO, the C9000 is still the best nimh aa/aaa charger out there. It would be nice though if Maha made a li-ion version of the C9000. 
Why? Charging Li-Ions is easy as hell, there’s no need for electronics as sophisticated and expensive as you can find in C9000 for any rechargeable Lithium chemistries.
Why? Because I want one! 
Well ok, there you go, then:
Does NiMH/NiCd's as good as C9000, and Li-Ion's/LiFe's/SLA's as good as you can get (basically it always uses perfect charging algorithms)
I've been thinking about getting one for a long time now. What do you use for a power supply? Link? Thanks.
I use this:
But you can use any 12V - 18V adapter with compatible plug (5.5x2.5mm, e.g. laptop charger)
Oh ok, I think I have a couple of them somewhere around the house. Thanks.
Just make sure it's output power is enough (e.g. charging a battery at 4.2V 5A requires 21 watt of power, make sure you use a brick rated 30W or higher.. et cetera). If you don't have any powerful bricks on hand, just use smaller charging currents.
