    Ummm nope, NiCad's are nominally around 1.25v
    NiMH nominally around 1.35v

  2. Nominal voltage for both is around 1.2v per cell median discharge, 1.4
    fully charged.

  3. They are virtually identical. both will take a surface charge up to
    maybe 1.5v per cell, but it only last seconds..

  4. This is essentially the strategy used by battery powered smoke alarms.
    The LED flash is actually there to provide the load. They only measure
    on load voltage.
