Hioki BT3554-51 Battery Tester (with 9465-10)
The BT3554-51 is the BT3554 battery internal resistance tester supplied with the PIN TYPE LEAD 9465-10 — the standard probe for measuring valve-regulated lead-acid (VRLA) batteries commonly used in UPS systems and telecom backup power. The 4-wire AC resistance measurement method eliminates contact resistance from the measurement, giving accurate cell resistance readings even through aged terminals.
Key Features
- 4-wire AC internal resistance measurement — immune to contact resistance
- Internal resistance range: 3mΩ to 3100mΩ (resolution 1μΩ on lowest range)
- Measurement frequency: 1 kHz ±30Hz (noise-tolerant during UPS operation)
- DC voltage measurement: 6.000V to 60.00V
- Temperature measurement: -10°C to 60°C (when using 9460 temperature probe)
- Memory: up to 6000 data points
- Bluetooth wireless via Z3210 adapter — Gennect Cross app voice guidance for sequential battery bank testing
- USB data transfer to PC
- Comparator PASS/WARNING/FAIL function
- LR6 alkaline batteries ×8, approximately 8.5 hours
- 199 × 132 × 60.6mm, 960g
