Spare HDMax Kodak Camera Compatible Battery 3.7V 1050mAh

Spare HDMax / HD96 — 3.7V Li-ion Replacement Battery (US624136A1R5)

This is a 3.7V, 1050mAh Li-ion cell built to replace the original battery in the Kodak EasyShare HDMax and HD96 digital cameras. It matches the OEM voltage and capacity so the camera body receives the correct power rail for shooting, video recording, and menu operation. Dimensions are 40.20 × 40.90 × 6.50mm — the same footprint as the factory cell.

• HDMax and HD96 compatibility: Both models share the same battery bay dimensions, connector pinout, and 3.7V supply requirement, which is why a single cell — part number US624136A1R5 (also listed as KB-05) — covers both.
• Bench tested on actual hardware: We cycled this cell through the OEM charger and monitored BMS handshake at charge acceptance. The protection circuit tripped correctly at the low-voltage cutoff and resumed charge without manual reset.
• First-install charge cycle: Run one full charge inside the camera body or OEM charger before shooting. Some Kodak BMS firmware needs that first in-body cycle to calibrate the battery-remaining indicator accurately — skipping it can cause the percentage display to jump.

Camera showing dead battery indicator on a partially charged replacement cell

The HDMax maps its battery-remaining indicator to a voltage-threshold table calibrated against the original cell's discharge curve. A new third-party cell can sit at 3.6V and still read as dead because the camera hasn't yet learned the new cell's curve. One full charge-and-discharge cycle through the OEM charger resets that mapping. After the first cycle, the indicator tracks normally across the full range.

Battery percentage jumping erratically mid-shoot

This happens when the camera's voltage-to-percentage lookup table doesn't yet align with the new cell's discharge profile. The indicator can drop sharply during a burst shot — where current draw spikes — then recover when the load drops. It's a display calibration issue, not a fault with the cell itself. Complete two full charge cycles in-body and the percentage readout stabilises; if it still jumps after two cycles, check that the battery contacts read at least 3.7V with a multimeter before loading it into the camera.
