ZIBOO L2020 Generic Curved Type Lead Pin Type 4 Terminal Probe ,Pin-Type Lead Compatible with Hioki BT3554-10/11, BT3563,BT3562,BT3561,UNIT UT-677A Battery Tester Battery HiTester, Handheld Battery Tester
Engineered for Maximum Access & Precision
The ZIBOO L2020 curved pin probe delivers professional-grade battery testing in cramped environments. With its patented 90° L-shaped tip, reach behind panels or into dense battery arrays without bending wires. The extra-long 96.5-inch (245cm) silicone leads stay tangle-free while testing distant terminals.
Key Features That Outperform:
✅ Hioki Compatibility
Seamlessly connects to Hioki BT3554-10, BT3554-11, and other handheld battery testers (tested to ±0.05% contact resistance vs. OEM).
✅ 4-Terminal Kelvin Sensing
Eliminates lead resistance errors for true voltage/current readings—critical for EV batteries and solar storage maintenance.
✅ Industrial Durability
Oil-resistant silicone jackets (-40°F to 392°F)
Gold-plated pins resist corrosion (10x insertion cycles)
Reinforced stress relief joints prevent breakage
✅ Ergonomic Efficiency
The curved design allows one-handed operation when probing vertical bus bars or cramped battery racks.
Bullet Points
