BenQ NP-60 DC 5330 Replacement Battery 3.7V 1050mAh

BenQ DC 5330 / DC C50 / DC C60 — 3.7V Li-ion Replacement Battery (NP-60)

This is a 3.7V, 1050mAh Li-ion replacement cell for the BenQ DC 5330, DC C50, and DC C60 digital cameras. It slots into the same battery bay as the original NP-60 and connects to the same BMS contacts. Use it as a spare or to replace a degraded original cell.

• DC 5330, DC C50, DC C60 compatibility: All three cameras run the same NP-60 form factor, voltage rail, and BMS contact layout. One cell covers all three models — no adapter or wiring change needed.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on a BMS-active test rig. The protection circuit tripped correctly at low-voltage cutoff and released cleanly on charge resumption — no latched fault states.
• First-use charge cycle on BenQ cameras: Insert the new cell and run one full charge through the OEM charger or the camera body itself before heavy shooting. Some BenQ camera BMS systems recalibrate the battery-remaining indicator only after an internal charge cycle — skipping this step can cause the display to read inaccurately from the first shot.

Dead battery indicator on a replacement NP-60 that still has charge

BenQ DC-series cameras map their battery gauge to a discharge curve profiled during an internal charge cycle. A new cell that has never been charged inside the camera body can trigger a false low-battery or dead-battery icon even at 3.6V or above. The camera's fuel gauge logic doesn't yet have a reference curve for the cell. One full charge cycle inside the camera body — not just an external charger — resets that mapping and clears the false indicator.

Battery percentage jumping between readings mid-shoot

This happens when the camera's voltage-threshold table doesn't match the actual discharge curve of a new replacement cell. The indicator can jump from 60% to 20% in a few frames, or hold at one level then drop suddenly. It's a calibration gap, not a fault with the cell itself. Charge the battery to full via the camera body, shoot until empty, then charge fully again — after one complete cycle the readings typically stabilise.
