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.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eExtreme Silver and Extreme Gold compatibility:\u003c\/strong\u003e\n    Both models share the same cell format, voltage rail, and connector pinout.

Some GoClever BMS firmware requires an in-body charge cycle before the battery-remaining indicator maps accurately to the new cell's discharge curve.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the GoClever DVR shows a dead-battery indicator on a freshly installed replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 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.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping or resetting mid-recording after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis 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.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333857181786,"sku":"BWCS-LI40B-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333857214554,"sku":"BWCS-LI40B-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333857247322,"sku":"BWCS-LI40B-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LI40B-1.webp?v=1778213291","url":"https:\/\/batteryweb.com\/products\/goclever-dvr-extreme-silver-replacement-battery-37v-660mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
