voltage level, about 99 percent of the energy is spent in starts
to voltage drop quickly if the discharge continues. Downloads beyond the date-off
voltage should be avoided, especially under heavy loads. Since the cells of a battery pack
cannot be perfectly, a voltage potential negative (cell reversal)
across a cell weaker occurs when the discharge is authorized to continue beyond
the a cutoff point. The greater the number of cells connected in series, the
greater the likelihood of this occurring. A NiCd battery can tolerate a
limited quantity of cells inversion, which is typically about 0.2V. During that
time, the polarity of the electrode is positive reversed. This condition
can will only be sustained for a brief moment because hydrogen occurs on
the positive development electrode. This leads to pressure build-up in cells of ventilation. More information: www.good-battery.co.uk
