Research indicates that internal battery cell impedance increases with the age and discharge history of a cell. Since interruption in electrical service can spell disaster, a reliable backup power system is critical so that when conventional power fails, costly service outages can be avoided.
The BITE%u2122 family of products provides meaningful data on battery health without significant expense or reduction in remaining battery capacity. The BITE products are designed for on-line ac impedance and dc terminal voltage measurement of secondary batteries.
