    Nimh AA battery charger monitors voltage / temp to cease charging, do
    they do this individually each battery, or in pairs.


    Also, best way to recharge solo battery, with another charged battery,
    with battery replacement adaptor (Short circuit) (ie 3 batteries in 4
    battery holder a la Maplin)

    Depends on the charger.
    Most charge pairs. Most do a lousy attempt at temperature sensing.
    The good ones look at changes in voltage, not the absolute value.
    NEVER, EVER try to charge one cell in a charger designed for 2 cells.
    Never, EVER try to FAST charge a dead cell and a charged cell in series.

    I have a one-cell mp3 player. I run down two then charge them together.
    I always run them till it shuts off so I can count on the state of
    discharge being similar.
