NCA-K/102 Kodak PlaySport Zx5 Replacement Battery 3.7V 1000mAh

Kodak PlaySport Zx5 / PIXPRO SP1 — 3.7V Li-ion Replacement Battery (NCA-K/102)

This is a 3.7V, 1000mAh Li-ion cell that fits the Kodak PlaySport Zx5 and the PIXPRO SP1 series, including the SP1 HD and SP1-YL3. It replaces OEM part numbers NCA-K/102 and LB-080. Same voltage, same capacity, same physical footprint at 40.20 × 35.30 × 9.60mm.

• PlaySport Zx5 and PIXPRO SP1 compatibility: Both cameras share a common 3.7V single-cell battery bay with an identical connector and BMS handshake protocol. The same cell fits across the Zx5, SP1, SP1 HD, and SP1-YL3 without modification.
• Bench tested on actual hardware: We cycled this cell through the SP1's charge circuit and confirmed the BMS accepted it without fault flags. Charge termination triggered correctly at 4.2V, and discharge cutoff engaged at the expected low-voltage threshold.
• First charge cycle on the SP1: Run the first full charge from within the camera body using the OEM USB cable or charger — not a third-party USB adapter. The SP1's BMS maps the discharge curve for battery-remaining accuracy during that initial cycle, and doing it in-body gives the most consistent calibration.

Why the PlaySport Zx5 shows a dead battery indicator on a partially charged replacement cell

The Zx5 reads battery level by mapping voltage to a fixed discharge curve stored in firmware. A new replacement cell has a slightly different internal resistance profile than the original cell that curve was built around. Until the camera completes one full charge-discharge cycle with the new cell, the voltage readings can fall outside the expected range and trigger a false low-battery warning. This is a calibration gap, not a faulty battery. Run one full cycle — charge to 4.2V, shoot until the camera shuts off — and the indicator typically stabilises.

Battery percentage jumping erratically during playback or video recording

Sustained video recording on the SP1 pulls more current than photo capture — sensor, processor, and write buffer all draw simultaneously. Under that load, a new cell's voltage sags briefly, and the camera's indicator can jump several percent in either direction if the BMS hasn't yet mapped the cell's actual discharge curve. This is not capacity loss. It corrects itself after one or two full charge cycles as the firmware locks onto the new cell's voltage-to-charge relationship. If the jumping persists past three cycles, check that the battery contacts in the bay are clean and making solid contact — a resistive connection amplifies voltage sag readings.
