    Default Looking for an AA battery analyser

    Iíve got a lot of AA Eneloops many of which were purchased years ago and used a lot. I havenít done a good job of marking them so all of the cells are more or less mixed with newer ones.

    Iím looking for suggestions on a battery analyser that can tell me a cells capacity or anything else that would indicate overall health.

    Ive got a decent charger (Nitecore D4) so charging is not a requirement but Iím guessing is included in analysing. I used to have a Maha Powerex MH-C9000, probably shouldnít have sold that. Maybe thereís something more advanced now though.

    Thanks.

    LaCrosse BC700, NiMH/NiCad AA/AAA charger that can refresh, discharge, and test capacity.

    Get an analyser that measures internal resistance. It is a good indicator of overall health. Or an analyser that lowers the charge/discharge current for high-IR cells.

    Get an OPUS BT-C2000 or any of its clones, like everActive NC-3000. Or get the smaller OPUS BT-C700.

    I recently bought a Miboxer C4 charger and have been pleased with its features;
    http://www.candlepowerforums.com/vb/...ger-Miboxer-C4
    It provides measurements of cell resistance, a count of the mAH charged into the cell and 1 of the 4 slots will do a full charge-discharge-charge cycle to more accurately measure the mAH capacity.
    I used the MiboxerC4 to evaluate & sort my collection of 50+ various rechargeable batteries. It was very useful for identifying the individual cells that were too worn for continued use and for identifying the cells that were still good performers.

    Just get another Maha 9000 if you're only concerned with NiMH batteries.

    Why you would have sold it, I don't know?

    It's a pretty good unit and gives us a wealth of info.

    How about the Xtar Dragon plus? I'm thinking it might give more accurate IR readings?

    The C9000 is pretty good, although I noticed i had left some cells discharged for several (if not longer) months and my AAA cells showed high (my eneloop pros). My La Crosse charger will accept them and I did a 1Amp charge on them for a few minutes to get 30-50mAh in and the cells IR lowered when I tried them again in the C9000. Seems the pros don't hold up very well in storage but I did want to see what would happen if I charged them at a high rate and it looks like charging them will lower IR, on a good set of cells anyway.

    Thanks everyone for the suggestions. Iím thinking about the LaCrosse or another C9000. Iíll let you know which one I decide on and for what reasons.

    Thanks!

    Get another Maha.

    I bought a BC-700 and my C9000 at the same time and I wish that I had just bought another C9000, as it's a more capable charger in every meaningful regard.

    I had the BC-700 and the BC-900 as well as the C9000.
    The word "High" on the C9000's display was in contrast to the LaCrosse which charged the AAAs without much trouble.

    The problem of the C9000 is in the high peak current (about 2000mA) which recharges the AAA with too much force:




    Today the simplest solution is the BT-C700 which forces the peak to about 1000mA:



    Before the tests of HKJ these things could only be imagined but without giving a proven reason, we talk about 10 years ago ... a long time ago.

    The almost perfect solution is a SKYRC MC3000, but I do not recommend it so much.
