ITT NP-552 Camera Replacement Battery 6V 2100mAh Ni-MH

ITT NP-552 / NP-554 Series — 6V Ni-MH Replacement Battery

This is a 6V 2100mAh Ni-MH replacement battery for ITT cameras including the NP-552, NP-554, V8-130, and V8-230 among others. It matches the original cell's voltage and form factor. Capacity is 2100mAh (12.6Wh), sourced to spec — not inflated.

• NP-552 and NP-554 platform compatibility: These models share the same 6V voltage rail and physical housing, which is why one cell covers the full range. The BMS in each body expects the same charge acceptance profile, so the same Ni-MH cell works across the cluster without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the bench and confirmed the BMS accepted the cell without flagging an incompatible battery error. Charge termination triggered correctly at full capacity.
• First-cycle charge via camera body: On first use, run a full charge cycle through the camera body rather than a standalone third-party charger. Some ITT camera BMS systems calibrate the battery-remaining display only after an initial charge cycle completed inside the body — skipping this step can cause inaccurate percentage readings from the start.

Battery percentage jumping erratically on the ITT camera display

Ni-MH cells have a flatter discharge curve than lithium chemistry. The camera's battery gauge was calibrated for the original cell's specific voltage-to-capacity mapping. A new replacement cell — even a correct one — can cause the indicator to jump because the camera is reading voltage thresholds that don't align with the new cell's curve until it has been cycled. Run two to three full charge-discharge cycles through the camera body. After that, the gauge stabilises and tracks the actual remaining capacity accurately.

This happens when the camera reads an open-circuit voltage below its low-battery threshold — common on a new Ni-MH cell that shipped in a partially discharged state. The BMS cuts the display before the cell is actually depleted. Place the battery in the OEM charger or charge via the camera body until the charge indicator confirms full. Once voltage rises above approximately 7.2V at full charge across the cell stack, the camera will read correctly and the false low-battery flag clears on its own.
