Product Details

Megger BITE3 Battery Impedance Test Equipment determines the health of lead-acid cells up to 2000 Ah. The BITE3 measures cell impedance, an internal ohmic test, cell voltage, intercell connection resistance and ripple current. 


The Megger BITE3 battery impedance tester 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 quick, reliable and easy to use.


With a rapid test time, one person can easily, quickly and precisely measure cell and string parameters without taking the system off line. Determines health of lead-acid cells up to 2000 Ah On-line testing with Pass/Warning/Fail calculations Measures impedance, interconnection resistance and cell voltage Windows CE operating system with 32 MB of memory Measures float and ripple currents Documents battery test requirements outlined in NERC PRC-005-2. Meets testing recommendations outlined in IEEE 450, 1188 and 1106 Practice and Maintenance Guides.
