(More customer reviews)I bought this unit from a local store - same model number etc, OK ? Now I'm checking this site's reviews better!
I have many NiMH AA & AAA batteries that have been working but I have noticed shortened life on. I talked to some friends and decided I needed a battery charger with a re-conditioner feature. This package came with 4 hi capacity AA batteries and for the price it looked like what I wanted.
First, I read instructions and saw AA's had to be of 2000Ma minimum, my old ones were rated as such so I figured it would be OK. I plugged in two of my old batteries and the unit began flashing the LED's ( manual indicated this means a a fault - batteries are dead, can't be charged :: yes I was reading the manual ! ). I pressed on the button you are supposed to for the discharge / condition feature to kick in - still fault light. I tried two others, same result. Two others, same result !
Also, upon looking closer at the manual this charger apparently ONLY charges in fast /quick charge mode ( 1 hour ). I know that this is harder on batteries ( shortens their life ). From what I now know, a true smart charger will adapt it's charging profile for the battery it is trying to charge - some even let you tweak it.
I have the notion that even though my old AA batteries are rated @ 2000 mAh ( MINIMUM recommended for AA's in this charger) , maybe their true capacity is now under their stated rating and it senses these are not up to it's charging profile ?
To me, this indicates the unit will not charge or recondition my existing batteries ! ( the reason I bought it ! )
I did charge the AA's that came with it and everything seemed OK - I never checked temperature or true charge time since I did it overnight.
I'm now reading about the Maha Powerex MH-C9000 WizardOne Charger-Analyzer ( also available at the same local store - about $5 more than here, but will have tonight ) it's reviewers here say it senses bad batteries better and changes it's charging profile, also you can really tweak how each of 4 batteries charge ( though a little tedious, apparently ) . Maybe I'll give it a shot.

Bring dead batteries back to life Like a well conditioned athlete, batteries also need to be conditioned from time to time so that it can produce maximum performance in all of your equipment. Batteries that were ready for the recycle bin may be brought back to life using the conditioning feature. The conditioning feature is also an useful tool at reviving poorly performing batteries.
