Xiaomi AZ16 Replacement Battery 3.8V 1160mAh Li-ion AZ16-1

Xiaomi AZ16 — 3.8V Li-ion Replacement Battery (AZ16-1)

This is a 3.8V 1160mAh Li-ion cell built to the AZ16-1 specification. It fits the Xiaomi AZ16 compact digital camera. Capacity figure comes from the product data: 1160mAh / 4.41Wh.

• AZ16 platform fit: The AZ16 camera uses a single-cell Li-ion pack with a 3.8V nominal rail and a compact 35.56 × 35.10 × 10.50 mm footprint. This cell matches that voltage rail and form factor so the BMS handshake completes normally on install.
• Bench tested on actual hardware: We cycled this cell through the AZ16 camera body and an external OEM-spec charger. The BMS accepted the cell, reported charge state correctly, and did not flag a protection cutoff at either end of the charge curve.
• First-cycle charging on the AZ16: Run the first full charge cycle inside the camera body or through an OEM-compatible charger. Some AZ16 BMS firmware maps the battery-remaining indicator during that initial charge cycle — skipping it can cause the display to read erratically from the start.

AZ16 battery indicator stuck at full or dropping suddenly to empty

The AZ16 maps its fuel gauge against a discharge curve stored in firmware. A new third-party cell has a slightly different discharge curve than the original, so the indicator can read incorrectly until the BMS calibrates. Run one full charge-to-discharge cycle without interrupting it. After that cycle, the camera firmware re-anchors its voltage thresholds to the new cell's actual curve and the display stabilises.

Flash recycling slowing down mid-shoot on a new AZ16 cell

The AZ16 flash capacitor pulls a sharp recharge current after each firing. Early in a cell's life, internal resistance is slightly higher than it will be after a few break-in cycles, which extends capacitor recharge time by a fraction of a second. This is not a fault — it resolves after three to five full charge cycles as the cell's internal resistance drops to its rated level. If slow recycling persists beyond ten cycles, check that the battery contacts in the camera body are clean and making full contact.
