It carries a 1250mAh (4.63Wh) capacity and slots directly into the Vx8 battery compartment using the original OEM part number 02491-0028-01. Use it to restore full camera operation when the factory cell no longer holds a usable charge.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVx8 battery compartment fit:\u003c\/strong\u003e\n    The Vx8 draws power from a single-cell 3.7V Li-ion pack at fixed dimensions — 41.95 × 36.05 × 9.80mm. Any cell outside these tolerances won't seat correctly or close the compartment door. This replacement matches those dimensions and the OEM connector orientation exactly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the Vx8 platform. The camera's BMS accepted the cell, reported charge status on the indicator, and drew current without triggering an undervoltage cutoff at rest state or under shutter load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge protocol for the Vx8:\u003c\/strong\u003e\n    Insert the new cell and charge it fully inside the camera body using the OEM charger before your first shoot. Some Vx8 BMS implementations calibrate the battery-remaining display during this first in-body charge cycle — skipping it can cause the indicator to read inaccurately from the start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDead battery indicator on a replacement cell that still has charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell ships at partial charge — typically 40–60% of nominal voltage. The Vx8's battery indicator maps remaining capacity against a stored discharge curve from the previous cell. If the BMS hasn't yet calibrated to the new cell, it can read the resting voltage as critically low and show a dead-battery icon even when the cell is not depleted. Running one full in-body charge cycle from near-empty to 4.2V resets that calibration. After that cycle, the indicator tracks the new cell's discharge curve correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the Vx8 display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the camera's voltage-threshold table doesn't yet match the discharge curve of the replacement cell. The Vx8 estimates remaining charge by measuring cell voltage at intervals — if the new cell's voltage drops at a slightly different rate than the OEM cell, the percentage readout skips or jumps between values. It's not a fault with the cell. Discharge the battery fully during a normal shoot, then charge it to 4.2V in one uninterrupted session inside the camera body. That single calibration cycle typically stabilises the display.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333845221466,"sku":"BWCS-PRD8330-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333845254234,"sku":"BWCS-PRD8330-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333845287002,"sku":"BWCS-PRD8330-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PRD8330-1.webp?v=1778213402","url":"https:\/\/batteryweb.com\/products\/megapix-vx8-replacement-battery-37v-1250mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
