BenQ DCL1050 Replacement Battery DLI-213 3.7V 720mAh

BenQ DCL1050 / DC E1050t / DC E1220 — 3.7V Li-ion Replacement Battery (DLI-213)

This is a 3.7V, 720mAh Li-ion battery built to the DLI-213 specification. It fits BenQ compact digital cameras including the DCL1050, DC E1220, and DC E1050t. Swap it in when your original cell no longer holds a charge or the camera shuts down mid-use.

• DCL1050, DC E1220, DC E1050t compatibility: These three BenQ models share the same battery bay dimensions and voltage rail. The DLI-213 form factor — 39.50 × 35.40 × 5.60mm — fits all three without modification, and the 3.7V nominal matches the camera's power circuitry exactly.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the bench using the DLI-213 profile. The BMS accepted the cell without errors, held voltage within spec through the full discharge curve, and cut off cleanly at the low-voltage threshold.
• First-use charge cycle on the DCL1050: On first install, run one complete charge cycle through the camera body or OEM charger before shooting. Some BenQ compact bodies need this cycle to calibrate the battery-remaining indicator against the new cell's discharge curve — skipping it can cause the display to read inaccurately from the start.

BenQ compact cameras map their battery indicator to a voltage-threshold table stored in firmware. A brand-new cell's discharge curve can sit slightly outside what the camera expects before it has been calibrated. The result is a low-battery warning — or even a shutdown — at what is actually 60–70% charge. One full charge cycle from empty to 4.2V, completed inside the camera body, resets the indicator mapping to the new cell and clears the false low warning.

If the percentage counter skips — say, from 80% to 40% in a single burst of shots — the camera's voltage sampling is reading the new cell's discharge curve at the wrong breakpoints. This happens because compact cameras with simple coulomb-counting firmware recalculate state-of-charge from spot voltage readings rather than continuous current tracking. The fix is to drain the battery fully until the camera powers off, then charge it uninterrupted to 4.2V. After that one anchor cycle, the firmware recalibrates its breakpoints and the display stabilises.
