Hioki BT3554-52 Battery Tester (with L2020)
The BT3554-52 is the BT3554 battery tester supplied with the L2020 PIN TYPE LEAD — a longer-reach probe designed for battery cabinets and racks where access is restricted and standard probes cannot reach between cells. Functionally identical to the BT3554-51, the L2020 probe makes it better suited to large UPS battery strings in enclosed cabinets.

L2020 vs 9465-10 Probe
The L2020 has a longer body and extended reach compared to the 9465-10, making it better for reaching battery terminals in deep or enclosed battery racks. If your UPS batteries are in an open cabinet with easy access, the BT3554-51 with 9465-10 is sufficient. For enclosed racks with restricted access, the BT3554-52 with L2020 is the better choice.
Applications
Large UPS battery string testing in enclosed cabinets, data centre battery maintenance, telecom battery banks, industrial backup power system maintenance.
