The Hioki BT3554-50 Battery Tester sets a new standard for UPS and lead-acid battery diagnostics. Since the battery’s internal resistance and voltage are measured using the impedance method, diagnostics can be performed while the battery is connected to its host device, without taking it offline. Proprietary noise reduction technology allows more accurate measurement, even in noisy environments. The specially designed L2020 Pin Type Lead further improves testing efficiency with an L-shaped tip that lets you reach deep into the battery racks to completely probe the terminals.

When the BT3554-50 is paired with a dedicated mobile app (GENNECT Cross), the mobile device will provide audio guidance announcing the next battery number to be measured. This feature helps prevent erroneous measurements. You can also set up measurement information and battery numbers in advance to create profiles to which measurement data and diagnostic results will be linked. This capability simplifies data management, even when performing diagnostic work on large numbers of batteries.
