BITE5 battery tester

Impedance, or ohmic, tester for lead-acid, NiCD, and lithium-ion batteries

Accurately measure battery cell impedance, voltage, temperature, and inter-cell resistance, with support for discharge testing.

About the product

The BITE5 and BITE5 Advanced battery testers let you perform simple tests to quickly evaluate the state of health of lead-acid (VLA and VRLA), NiCd, and lithium-ion batteries. Both instruments have an easy-to-use touch-screen interface and support impedance testing and discharge testing when used in conjunction with a load bank. The BITE5 Advanced allows you to monitor batteries and cells during recharging and test parallel strings without segmenting. With the BITE5, you can perform tests on modules up to 200 V and, with the BITE5 Advanced, on modules up to 500 V.

Measurement options provided by the BITE5 include cell impedance, cell voltage, ripple voltage, AC ripple current and DC float current. The BITE5 Advanced supports all of these tests and also has provision for accurately measuring inter-cell (strap) resistance. 

For impedance tests, you can set pass, warning, and fail limits for impedance and voltage. For discharge tests – and recharge tests with the BITE5 Advanced only – measurements are recorded throughout the full discharge or recharge period. Trends can be displayed on the instrument’s touch screen, and stored results can be downloaded via a USB cable or an SD card for further analysis and archiving. Wireless transfer of data to Megger’s PowerDB software suite is also supported.

Both the BITE5 and BITE5 Advanced support voltage measurement up to 1000 V DC and 600 V AC, which means you can use them to measure solar combiner boxes and check the input and output voltages of inverters used in renewable power systems. An additional feature of the BITE5 Advanced is an RFID tag reader, which allows the instrument to recognise assets without requiring manual data entry.
