The Megger 34943 series probe extension kit for the BITE 2/2P series includes two probe extensions and a variety of tips for reaching hard-to-reach battery terminals and connectors on batteries housed in cabinets and racks. They are for use with the Megger BITE 2 and BITE 2P battery impedance testers. The probe extensions are made of glass fabric tubing, and they are threaded for secure connection to the BITE 2 and BITE 2P receiver using the rod-receiver adapters (included). The kit comes with two rod-receiver adapters, two straight probe tips, two hooked probe tips, two 90-degree probe tips, and two 45-degree probe tips for accessing difficult-to-reach battery terminals and connectors.

Battery testers are used in the industrial, commercial, medical, telecommunications, aircraft, power utility, and military industries to detect the health 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-acid, 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 health, it is important to use the same tester for consecutive tests on a single battery when analyzing changes in battery health over time.
