Overdischarge - The process of discharging a cell or battery beyond its cutoff voltage and possibly into voltage reversal.
Ambient Temperature - The average temperature of the surroundings.
Fuse - Device used for cutting off an electrical current in the event of an abusive condition.
Safety installation - Installation supplying electrical equipment which may have a direct effect on the safety of users and must therefore remain energized even in the event of a mains failure. In general, characteristics concerning the power supply and conditions for transfer to the safety source for such electrical equipment are covered by applicable regulations.
Harmonic Sinusoidal - Term of the Fourier series expansion of a periodic function. The harmonic (or harmonic component) of the nth order is characterized by - Yn is the rms value of the given harmonic component, w is the angular frequency of the fundamental, related to frequency by - w = 2_f; phin is the phase angle of the given harmonic component at t = 0.
Voltage Reversal - The changing of the normal polarity of a battery due to overdischarge.
Polarity - In electricity, the condition of being positive or negative.
