GoClever DVR EXTREME SILVER Replacement Battery 3.7V 660mAh

GoClever DVR Extreme Silver / Extreme Gold — 3.7V Li-ion Replacement Battery

This is a 3.7V 660mAh (2.44Wh) Li-ion cell for the GoClever DVR Extreme Silver and Extreme Gold dash cameras. It fits directly into the camera body and restores continuous video recording capability when the original cell has degraded. Dimensions are 40.00 × 31.10 × 5.90mm — check these against your existing cell before ordering.

• Extreme Silver and Extreme Gold compatibility: Both models share the same cell format, voltage rail, and connector pinout. One replacement covers either unit without modification.
• Bench tested on actual hardware: We cycled this cell through the GoClever body and confirmed the BMS accepted the cell, voltage regulation held steady across the recording loop, and no overcurrent flags were thrown on a cold start.
• First-cycle initialisation on dash cam BMS: Run the first full charge through the camera body itself, not an external charger. Some GoClever BMS firmware requires an in-body charge cycle before the battery-remaining indicator maps accurately to the new cell's discharge curve.

Why the GoClever DVR shows a dead-battery indicator on a freshly installed replacement

The GoClever DVR Extreme series uses a voltage-threshold system to estimate charge level. A new cell shipped in storage state typically sits at 3.6–3.7V, which the camera firmware can misread as critically low or flat. This is not a fault with the cell. Plug the camera into USB power and allow a full charge cycle — the BMS will re-map its thresholds against the new cell and the indicator will read correctly from the next use.

Battery percentage jumping or resetting mid-recording after replacement

This happens when the camera's fuel gauge has not completed a full calibration cycle with the new cell. The indicator was previously calibrated to the aged discharge curve of the original battery. A new cell discharges differently, and the firmware's lookup table no longer matches actual cell voltage at each percentage point. Run one complete discharge-to-cutoff followed by a full charge in the camera body — the firmware recalibrates and percentage readings stabilise. After that cycle, the display should track the cell down to the low-voltage cutoff at approximately 3.0V.
