• Analyzes the condition of lead- battery systems that have a capacity of up to 2,000 ampere-hours (Ah).
• Determines overall battery system and measures impedance, interconnection resistance, cell voltage, float current, ripple current, and the harmonic content of ripple current.
• Battery system remains connected for testing, avoiding downtime and the risk of damage present in load testing or other forms of battery testing.
• Runs Microsoft Windows CE operating system and has 32 megabytes (MB) of internal memory for storing test results.
• Comes with software that allows recorded data to be organized and analyzed over time to track trends in test results.

The Megger BITE3 battery impedance test equipment analyzes the condition of lead- battery systems that have a capacity of up to 2,000 ampere-hours (Ah) for battery maintenance applications in the industrial, commercial, medical, telecommunications, aircraft, power utility, and industries. It measures cell and string parameters to determine overall battery system , including the battery’s impedance, interconnection resistance, cell voltage, float current, ripple current, and the harmonic content of ripple current. The BITE3 allows the battery system to remain connected during testing, avoiding downtime. Because the BITE3 does not require battery discharge, there is less risk of damage to the battery during testing than with load testing or other forms of testing. The BITE3 runs the Microsoft Windows CE operating system and has 32 megabytes (MB) of internal memory for storing test data. A port on the transmitter supports data transfer to a computer, using the included RS232 data cable. The BITE3 comes with software that allows recorded data to be organized and analyzed over time to track trends in test results. It has a backlit liquid crystal display (LCD) that is readable in low light. It operates on a rechargeable nickel-metal-hydride (NiMH) battery pack (battery and AC charger included), and it has a low-battery indicator that indicates when the battery needs to be charged. It comes with dual-point Kelvin probe leads for taking measurements, and light-emitting diodes (LEDs) on the test leads provide information about the circuit condition and show whether or not measurements are being taken. The transmitter is housed in a hard plastic case, and it comes with a canvas carrying case for transport and storage of the tester and accessories when not in use.

Battery testers are used in the industrial, commercial, medical, telecommunications, aircraft, power utility, and industries to detect the of a battery. They can measure conductance, impedance, voltage, and current, among other parameters. Battery testers are designed for specific types of batteries, such as lead-, nickel-metal-hydride (NiMH) and alkaline batteries. Some testers require a load to be applied to the battery during testing, and some do not. A variety of test leads with contacts, probes, clamps, clips, and other connectors can be used to connect a battery to a tester. Since different testers can measure different parameters to calculate battery , it is important to use the same tester for consecutive tests on a single battery when analyzing changes in battery over time. Megger manufactures equipment for cable fault locating, protective relay testing, telecommunications and data integrity, and power quality testing under multiple brand names, among them Megger, Biddle, States, and AVO. The company, founded in 1889, is headquartered in Dover, England, and meets International Organization for Standardization (ISO) 9001:2008 standards.
