Measure the internal resistance and output voltage of a wide variety of batteries, including lead storage cells, nickel-cadmium, lithium-ion and nickel-metal hydride batteries with this tester.

The Extech BT100 uses a four-terminal measurement method when testing, eliminating the effects of lead and contact resistance to ensure accurate results. The meter is fully suitable for testing active (online) batteries without the need to disconnect.

This battery tester measures both battery voltage and resistance simultaneously to gain comprehensive, highly accurate results. A built-in datalogger can be used to manually store up to 999 sets of data and direct interfacing with PC allows the user to further interact with testing data by using Extech's included software package.
