Crest factor (Fc) - Ratio between the peak current value to the rms current value.
Constant Current Discharge - A battery discharge regime whereby the current drawn during the discharge remains constant.
Charge Control - Technique for effectively terminating the charging of a rechargeable battery.
Brownout - A steady state RMS voltage under nominal by relatively constant percentage.
Distortion (individual) - Ratio between the rms value of an nth order harmonic and the rms value of the fundamental.
Dry Cell - A cell with immobilized electrolyte. The term "dry cell" is often used to describe the Leclanche cell.
Constant Power Discharge - A battery discharge regime whereby the current during the discharge increases as the battery voltage decreases.
