Voltage Reversal - The changing of the normal polarity of a battery due to overdischarge.
Dry Cell - A cell with immobilized electrolyte. The term "dry cell" is often used to describe the Leclanche cell.
Depth of Discharge - The ratio of the quantity of electricity (usually in ampere-hours) removed from a battery to its rated capacity.
Crest factor (Fc) - Ratio between the peak current value to the rms current value.
Blackout - A zero voltage condition lasting for more than two cycles. Same as a power failure
IR Drop - A voltage drop associated with the electrical resistance (R) of a battery or current flow (I). The voltage drop is the product of the current (in amperes) and the resistance (in ohms).
Coulomb - The amount of electricity transported by a current of one ampere flowing for one second.
