It fits the PW-V1 body and restores full shooting capability when the original cell no longer holds adequate charge. Voltage and capacity match the factory specification — 3.7V, 1050mAh (3.89Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePW-V1 fitment:\u003c\/strong\u003e\n    The PW-V1 uses a slim 52.92 × 33.78 × 5.48mm cell format. This replacement matches those dimensions exactly, so the door closes flush and the contact pins seat correctly without forcing.\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 bench. The BMS held the cutoff voltage cleanly at both ends — no early shutdown and no overcharge bleed at the top of the curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle charge protocol for the PW-V1:\u003c\/strong\u003e\n    Charge this cell inside the camera body using the OEM charger or USB-C port before your first shoot. Some camera BMS systems only map battery-remaining percentage accurately after completing one full charge cycle from within the body itself.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePW-V1 showing dead battery indicator on a partially charged replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe PW-V1's fuel gauge reads voltage thresholds mapped to the discharge curve of the original cell. A new replacement cell has a slightly different resting voltage at partial states of charge, which can make the indicator read empty even when capacity remains. This is a calibration mismatch, not a fault in the replacement cell. Run one full charge-to-discharge cycle inside the camera body and the indicator will re-anchor to the new cell's curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the PW-V1 display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eErratic percentage jumps happen when the camera's voltage-to-percentage lookup table doesn't yet align with the replacement cell's discharge curve. The cell is delivering power correctly — the display is just interpolating voltage readings against a reference it hasn't recalibrated to. Perform a full charge cycle via the camera body. After that cycle, the BMS recalculates its reference points and the percentage readout stabilises. If it doesn't settle after two cycles, check that the battery contacts on both the cell and body are clean and making full contact.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333812748378,"sku":"BWCS-VD001MC-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333812781146,"sku":"BWCS-VD001MC-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333812813914,"sku":"BWCS-VD001MC-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VD001MC-1.webp?v=1778213259","url":"https:\/\/batteryweb.com\/products\/powerwalker-pw-v1-replacement-battery-37v-1050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
