The Megger BITE5 Battery Tester is capable of testing lead acid batteries, NiCD batteries, as well as lithium-ion batteries to evaluate their state of health status. The BITE5 measures and records battery voltage, impedance, and temperature, while also supporting discharge testing. Featuring an easy-to-use touch screen interface, the BITE5 supports both impedance testing and, when used in conjunction with a load bank, discharge testing. Tests can be performed on individual cells or on strings, up to a maximum cell voltage of 200 volts. This tester can measure the voltage, current, impedance, and temperature throughout the discharge cycle.

Battery Impedance Testing

The BITE5 can measure cell impedance, cell voltage, and temperature. The recorded data can be trended on the unit's touch screen and the user can view the trended data of each test or trend the data of each cell. Pass, warning, and fail limits can be set for voltage and impedance. With this unit, the user can record the ripple voltage, ripple current, and float current, transfer the recorded data via USB or via a SD card to the PowerDB software, then create custom reports and automated analysis.

Battery Discharge Testing

The BITE5 can record voltage, DC current, impedance, and temperature of each cell throughout the entire discharge test. The average impedance can be measured at the end of the commissioning test and used as a limit for future impedance tests. Trend the recorded data on the BITE5 touch screen and view the trended data of each test, or trend the discharge of each cell. The recorded data can be transferred via USB or via a SD card to the PowerDB software to create custom reports.

Solar Systems

The BITE5 is capable of measuring DC voltages up to 1000 volts and AC voltages up to 600 volts. This capability allows for the unit to measure and record solar combiner box DC voltages along with measuring the input and output voltages of inverters used in renewable power systems. Lithium-ion batteries can be tested as well.
