BenQ DC X600 Replacement Battery DLI-102 3.7V 850mAh

BenQ DC X600 — 3.7V Li-ion Replacement Battery (DLI-102)

This 3.7V, 850mAh Li-ion cell replaces the DLI-102 battery in the BenQ DC X600 compact digital camera. It slots directly into the same battery bay and connects to the same contacts the original cell uses. Capacity is 850mAh — identical to the factory specification.

• DC X600 fit: The X600 and its DC X600 variant share the same battery compartment geometry and contact layout. Both draw from the same 3.7V rail, so one cell covers either body without a wiring or connector difference.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on compatible hardware. The BMS accepted the cell without error flags, and voltage held steady across the discharge curve under both still and video draw.
• First-install charge cycle on the X600: On first use, run one full charge through the camera body or OEM charger before shooting. The X600's battery-remaining indicator calibrates its threshold map from that initial cycle — skipping it can cause the display to read inaccurately from the first frame.

Battery percentage jumping erratically on the X600 display

The X600 maps its battery indicator to a fixed set of voltage thresholds tuned to the original cell's discharge curve. A new replacement cell may discharge along a slightly different curve, especially in the first few cycles. This causes the indicator to skip segments or jump backwards as voltage crosses those thresholds at unexpected points. After two or three full charge-discharge cycles, the BMS reading stabilises and the display tracks more accurately.

A new Li-ion cell can arrive at a storage charge of around 3.5–3.6V — below the X600's low-battery cutoff threshold, which typically sits near 3.6V. The camera interprets this as a depleted cell and may refuse to power on or display a dead-battery icon immediately. The fix is to place the cell in the OEM charger or camera body and run one full charge to 4.2V before attempting to shoot.
