  1. Can I charged NiCad batteries in NiMH chargers? how about rechargeable

    I stronly suggest that you do not try that.
    They have different chemistries, and so have different charging
    And the alkalines have a much higher voltage.

    You can charge NiCad in a charger designed for NiMH, but you
    CANNOT charge NiMH in a NiCad only charger. While the
    charging regimens are similar, the deltaV termination method
    for NiMH requires greater precision not present in the NiCAD
    charger. NiMH chargers can also use deltaT termination methods.

    The end result of charging NiMH in a NiCAD charger is likely to
    be overcharging, overheating and venting. All bad for the battery.

    rechargable alkalines require a completely differnt kind of charger.

    Sure they can. But you had better monitor them very carefully as the end
    point detection process is slightly different for Nicad and NiMH. If you
    want your rechargeable batteries to last a long time then get a battery
    charger that switches itself off for the correct type of battery.

    As for alkalines, well, same applies except that the charging end point
    is quite different to Nicad and NiMH, as is the final charged voltage.
