HIOKI BT3554-52 Battery Tester (L2020 Lead) | UPS Battery Test

The HIOKI BT3554-52 battery tester shares the proven measurement platform of the BT3554 series and is bundled with the L2020 L-shaped pin-type lead set — specifically designed for accessing batteries in tightly packed rack-mounted UPS installations. The L-shaped probe tip reaches deep into battery racks, making contact with terminal posts that would otherwise be difficult to probe.

Like all BT3554 models, the BT3554-52 measures internal resistance and open-circuit voltage simultaneously and delivers instant PASS / WARNING / FAIL comparator judgements. Noise-reduction technology ensures reliable readings in active UPS environments where inverter noise can otherwise cause unstable measurements. The optional HIOKI Z3210 Wireless Adapter adds Bluetooth® connectivity to the GENNECT Cross app for wireless reporting.
