    I have a battery of NiCd's which is 6V nominal.

    I wish it to supply 0.714 Amps for 3 hours.
    -this is 3*60*60*0.714 Coulombs = 7714 Coulombs.

    If i am to charge this battery up for this service, and i have a 19 hour charge time
    then would i be right in saying that i need a constant charger current of 112mA?

    Multiply that by about 1.4 for nicads.

    Typically a C/10 charge is applies for 14 hours if you are not sensing the end of charge.

    Of course, the batteries need to be 2200mAh or more.
