(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.
