Megger BITE5 battery tester series
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.
- Data storage and communication: SD card
- Data storage and communication: USB
- Power source: Battery
- Test multiple battery types - The BITE5 and BITE5 Advanced will test lead-acid (VLA and VRLA), NiCd, and lithium-ion batteries.
- Support for battery discharge testing - While performing a discharge test with a Torkel test set, you can use the BITE5 and BITE5 Advanced to measure individual cell voltage, impedance and temperature throughout the test. This will help you identify weaker cells in the string and determine unique impedance baseline values.
- Touch screen setup and data trending - With the touch screen on the BITE5 and BITE Advanced you can review data immediately, evaluating individual cells or trending string data and cell performance. Get answers on the spot, make any repairs needed, and re-test to verify the repairs – all in a single trip to the site without transferring or printing data.
- Measure impedance on modules up to 500 V - New chemistries and applications mean higher voltage battery modules are becoming more common. The BITE5 can test modules up to 200 V DC, and the BITE5 Advanced can test modules up to 500 V DC.
- Measure inter-cell resistance - Using a higher test current, the BITE5 Advanced accurately measures inter-cell (strap) resistance, helping you identify poor or corroded connections.
- Reduce testing time - The BITE5 Advanced lets you test parallel strings without spending time isolating segments. It also includes an RFID tag reader for rapid battery identification without manually entering data.
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.
