    I'm not sure if I can ask this here but I'm sure someone will kno
    I am looking at this product a an option for an Ipod Video for extr

    Now it supposedly take 4 AA Alkaline batteries to attach to the Ipod'
    dock to extend when Battery power is depleted. Now I want to know i
    it would make any difference if I use 4 x AA sony Ni-Cd 2500 mA
    rechargeble batteries insted. That way I can recharge instead o
    using the throw away Alkaline's.

    By the way what mean "mAh" anyway , does it refer to the capacity o
    power of the battery

    So do you think this product would break down or worse the ipod woul
    break if high capacity rechargeble batteries would rush through thi

    Thank you so much

  2. It almost certainly won't hurt anything if you use Ni-Cad or NiMh
    cells, instead of alkalines, but the voltage will be lower, since both
    of the rechargeable types put out about 1.2 volts per cell, while
    the fresh alkalines put out about 1.5 volts. So the battery indicator
    will probably never read full voltage.
    That is an abbreviation of the product of milliamperes of output
    current times hours of operation... milliampere hours. Yes, it is a
    measure of the energy capacity of the batteries, assuming some nominal
    range of usable output voltage.
    No. As long as the cells produce no more voltage than the 4 alkalines
    do, the IPOD will draw the same current. Larger cells just last longer.

    The one other possible disadvange with rechargeables NiCd is that they have
    a high self discharge rate.
    Thus if you charge them but don't use them for a few days you may find them
