Midpoint Voltage - The voltage of a battery midway in the discharge between the start of the discharge and the end voltage.
Voltage-Keyed - A system which incorporates a mechanical identifier on batteries and devices to ensure only batteries of the correct voltage are connected to the device.
Thermistor - A temperature sensitive resistor, usually made from specially processed oxides.
Series - The interconnection of cells in such a manner that the positive terminal of the first is connected to the negative terminal of the second, and so on, resulting in increased voltage.
Tolerance in % - Limit for allowable variations for a given quantity, expressed as a percent of the rated value.
Microsecond - 1,000,000th of a second (mS).
Current Collector - An inert structure of high electrical conductivity used to conduct current from or to an electrode during discharge or charge.
