Electromagnetic compatibility - Possibility of a device to operate normally when installed near other devices, given the disturbances emitted by each device and their mutual sensitivities.
Brownout - A steady state RMS voltage under nominal by relatively constant percentage.
Power Surge - Voltage above 110% of rated RMS voltage for one or more cycles.
Coulomb - The amount of electricity transported by a current of one ampere flowing for one second.
Drain - The current withdrawn from a battery during discharge.
Current Collector - An inert structure of high electrical conductivity used to conduct current from or to an electrode during discharge or charge.
Micro-outage (or micro-interruption) - Total loss in the supply of power for 10 ms.
