Description
Suggested replacements for this discontinued product are the BITE5 and the BITE2/2P.
The 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) as well as 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.
The BITE3 is also quick and reliable. With a rapid test time, one person can efficiently and precisely measure cell and string parameters without taking the system off-line.

Frequently Asked Questions
How often should battery impedance testing be carried out?
The best frequency for impedance testing depends on the battery type, the site conditions, and previous maintenance practices. The IEEE 11888 standard for VRLA batteries recommends, for example, that a baseline impedance measurement is made six months after the battery has been put into service, and that further impedance measurements are made at quarterly intervals thereafter. For flooded lead-acid batteries, Megger recommends impedance testing at six monthly intervals. Impedance measurements should also be made immediately before carrying out every capacity test.
