Electrolyte
The medium, usually an aqueous salt solution (but may be a solid), that permits ionic conduction between the positive and negative electrodes of a battery.
Electromagnetic Interference (EMI)
1) Unintentional electromagnetic emissions (both radiated and conducted) by a circuit as a byproduct of normal operation, often interfering with other electronics. EMI of particular concern is radio frequency interference (RFI), which can affect radio and television reception.
2) The term EMI is sometimes used to refer to conducted emissions only, with radiated emissions referred to as RFI.
Equalization Charge
1.) The process of mixing the electrolyte in liquid electrolyte batteries by periodically overcharging the batteries for a short time.
2.) A periodic controlled overcharge for lead-acid batteries at a voltage level slightly higher than the normal end-of-charge voltage. Typically applied to batteries that have been in storage in order to provide cell equalization within the battery.
3.) A controlled overcharge as part of the IUI algorithm.
Exercising
A periodic discharge to one volt per cell applied to NiCd and NiMH batteries to halt or reverse the buildup of dendritic growths (crystalline formations). Should be applied once a month for NiCd batteries and once every three months for NiMH batteries.
