The instruments work by applying a test current across the battery string while on-line, then measuring the total current (AC ripple and test current) and the voltage drop of each cell/jar. It then calculates the impedance. They also measure DC voltage and interconnection (strap) resistance to help determine the overall condition of the entire battery string's electrical path from terminal plate to terminal plate. The BITE2 and BITE2P receiver stores the readings in its internal memory. These measurements, along with other maintenance data such as ambient and pilot cell temperatures and AC ripple current, assist in determining the overall condition of battery systems. Unlike load cycle testing that involves substantial downtime and repeated discharges, using these instruments requires no battery discharge, nor does it stress the battery in any way compared to other techniques. With a test time of less than 20 seconds for each cell and intercell connector, one person can easily, quickly, and precisely measure internal cell impedance, DC terminal voltage, and intercell connection resistance without taking the battery system off-line.
