Kodak LB-060 PixPro AZ521 Replacement Battery 3.7V 1100mAh

Kodak PixPro AZ521 / AZ526 / AZ525 / AZ501 Astro Zoom — 3.7V Li-ion Replacement Battery (LB-060)

This is a 3.7V, 1100mAh (4.07Wh) Li-ion cell built to the LB-060 specification. It fits the Kodak PixPro AZ521, AZ525, AZ526, AZ501, and twelve additional Astro Zoom models that share the same battery bay dimensions and connector. Swap it in when the original cell no longer holds a charge between shoots.

• Astro Zoom series compatibility: These Kodak Astro Zoom bodies share a common battery compartment geometry, connector pinout, and BMS handshake tied to the LB-060 cell profile. One replacement covers the full AZ5xx range without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on a PixPro AZ521 body. The BMS accepted the cell, the battery indicator populated correctly, and the camera exited low-battery lockout without a fault code.
• First-cycle charge procedure for Astro Zoom bodies: Charge this cell fully inside the camera body before your first shoot. The AZ5xx BMS recalibrates its battery-remaining display during the first in-body charge cycle. Skipping this step can cause the indicator to show full charge and then drop suddenly mid-session.

The AZ5xx battery indicator is mapped against voltage thresholds calibrated to the original cell's discharge curve. A fresh replacement cell discharges along a slightly different slope until the BMS has logged one full cycle. This mismatch can trigger the low-battery warning — or even camera shutdown — while the cell still holds usable charge. One complete in-body charge cycle from 0% to full recalibrates the threshold mapping and resolves the false cutoff.

The AZ5xx indicator estimates remaining charge by reading cell voltage at intervals and mapping it to a fixed lookup table. A new Li-ion cell has a flatter mid-range voltage plateau than a used cell, so the camera reads the same voltage at 80% and 60% and snaps between values abruptly. This is a display calibration issue, not a cell fault. After two or three full charge-discharge cycles, voltage behaviour settles and the percentage display stabilises — check that resting cell voltage reads between 4.15V and 4.20V after a full charge as a baseline confirmation.
