Megger BITE3 - Battery impedance Tester

The Megger BITE3 battery impedance tester determines the health of lead-acid cells up to 2000 Ah by taking measurements of the most important battery parameters. The BITE3 measures cell impedance, an internal ohmic test, cell voltage, intercell connection resistance, and ripple current. What's more, for the first time in a battery instrument, the BITE3 measures float current and the harmonic content of the ripple current. There is even a built-in spectrum analyser to show the harmonic content of the ripple current.
The BITE3 is one of the easiest instruments to use. Its measurements, along with temperature, specific gravity and other battery data, can provide the best basis for evaluating the overall health of batteries from terminal plate to terminal plate and, to a lesser extent, the charger (from ripple current and its harmonic content). Megger recommends that the BITE3 be made part of a comprehensive battery maintenance program with readings taken and recorded semi-annually for flooded lead-acid cells, and quarterly for VRLA.
