    I've just had a thought... This could be extended to be a battery meter calibrater. :)

    Run this overnight with your batteries, it takes statistics.
    Future battery meters read the stats file to display a battery meter relevant to your batteries! :)

    This is a great app. I got 3Hrs with my 8 month old 2500Ah Energizers.
    I am just wondering how speaker out put and volume would affect those stats.

    With my Energizer 2500mahs.. charged to the brim, meaning i kept unplugging and plugging in the battery charger once it had finished to get as much power as possible to them :)

    I do find it funny when I purchased mine how nearly everyone was saying "I get 4-5 hours battery life!". I had that same impression until I actually timed mine manually a few months back and found I was getting 2-3. The results from this app seem to confirm similar experiences for most (seems 3 is about average based on the reportings from that website, and that's at 200mhz).

    Perception is very different from reality for most of us I guess :)

    Is there any way to change the values the battery meter looks at to tell you remaining life? Most rechargables show up as medium charge just after charging. I'd like to set my battery meter to use the rechargable scale. AKA 2.4v as full not 3.0v

    with Clartech 1800Mah & Clartech fast charger

    Haven't tested with my 2700Mah battery set :(

    BTW : 972+752 /2 = ~862mA

    862x2,25 ~ 1940 mAh

    Seems like amperage decrease isn't linear, or my batteries are good ones ;)

    Hey, good to see another Maha fan in the audience..

    Here's my results using the Maha MH-C401FS charger with some Maha Powerex 2700mah batteries that have already been through a dozen cycles or so, using slow charges:

    STATISTICS:
    Clock Speed: 200 Mhz
    Running Time: 4:37:58
    Average FPS: 81.38

    Current charge: 10%
    Initial internal charge: 938
    Current internal charge: 675


    I'm guessing they'd actually go a full 4:45 but the 10 minute wait between writes doesn't allow it to show it.

    XD MAHA fans...

    The thing is with my test the charger was accidentally set on fast. I'll retry someday on slow to see if that makes a difference.

    Hi Folks just a little advice about testing your batteries, I know everyones keen to get down to testing their new batteries but do your testing after your batteries have been charged and run down at least 5 times as the batteries never get their full charge capacity until after 5 cycles.

    Also test your batteries several times to get some average results to ensure your results are not a freak result.

    -Be aware that recargeable batteries can go through dips in charge capacity at certain times in their life (how many cycles they have been through). So a much lower result than expected may not always be down to the charger it may be in one of these dips, the dips are pretty pronounced by the look of them so you'll know when you see one!.

    Also the testings not about bragging rights so don't try over charge them for your test charge them normally. The ideas for us to find out which rechargable batteries to buy to get the most bang for or buck and life out of our GP2x!

    Battery Conditioning (quote from the below site)

    See this website to see exactly how much capacity builds up over the first 5 charges!

    I've found thisinfo through looking at this testing site
