    I got the Microflyer R/C plane for chrismas. It has a 150 ma
    rechargeable lithum battery. I'ts gone through a few cycles but the
    charge light isn't lighting anymore. I can't think of any way I might
    have abused the battery, and I think the charger has an automatic shut
    off once th battery is chargged. The batteries in the controler/charger
    are good. Does any body have any ideas?

    From looking at the manual I would suggest:

    1) Read the manual
    2) Make sure all six batteries are in the correct polarity
    3) Make sure the toggle switch is in the center position

    Well.... er ummm, why not buy some of that old fashioned stuff called
    fuel? Stop mucking about Mate and re join the Luddites ;-) Electricity
    is invisable and therefor like a bloody ghost - catch you out when you
    least expect it and bloody unreliable if you ask me.....

  5. One of them might be open or shorted. Measured voltage at
    each cell separately. If normal (between 3.2 and 4.2V)
    connect to the load (about 1 hr discharge rate or higher) and measure
    voltage again. It should not drop more than by 200 mV. If it does for
    some cell, that cell is likely
    dead.
