Any single cell, NIMH or nicad, can be discharged to 0V. I discharge NIMH's routinely, to 0V. (as in shorted out overnight) Multiple cell packs increase the danger that one of the cells will hit full discharge before the others, and then the weak cell will effectively be reverse charged, which is VERY bad for them. Both Nicad and NIMH react the same way. Ref McGraw Hill's "HandBook of Batteries", and several manufacturer's data sheets. -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
