It replaces OEM part ZPT-NP60 across a wide range of Aiptek Pocket DV models including the DV-5700, DV-8700, and DV-8800LE. Dimensions are 53.20 × 35.30 × 7.10mm — verify against your existing cell before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePocketCam and Pocket DV compatibility:\u003c\/strong\u003e\n    These models share the same 3.7V single-cell architecture, connector pinout, and BMS handshake protocol — which is why one cell covers the full range. The voltage rail and physical form factor are identical across the DV-5700, DV-8700, DV-8800LE, and PocketCam 8900.\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 compatible Aiptek hardware. The BMS accepted the cell without fault codes, and protection circuits triggered correctly at low-voltage threshold — no runaway or false cutoff observed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle on camera body:\u003c\/strong\u003e\n    Charge this cell fully inside the camera using the OEM cable or charger before your first shoot. Some Aiptek BMS firmware maps the battery-remaining display against a charge curve it only learns during an in-body charge — skipping this step causes the indicator to read inaccurately from the first session.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera showing dead battery indicator on a partially charged replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe PocketCam 8900's battery indicator maps voltage thresholds against the discharge curve of the original cell. A fresh replacement cell has a slightly different resting voltage profile, so the camera reads it as empty even when it holds a charge. This is a calibration issue in the BMS, not a fault with the cell. Perform one full charge cycle inside the camera body — the firmware recalibrates its threshold mapping once the cell completes a full cycle from within the camera.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically during shooting\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the remaining-battery display jumps — say from 60% to 20% mid-session — the camera's voltage-to-percentage lookup is misreading the new cell's discharge curve. The ZPT-NP60 replacement cell's voltage sag under flash or continuous video draw differs slightly from the worn OEM cell the camera last calibrated against. Run one full discharge-to-cutoff cycle followed by a full in-body charge. After that cycle, the display stabilises to within a few percentage points of actual remaining capacity.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333910331482,"sku":"BWCS-NP60FU-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333910364250,"sku":"BWCS-NP60FU-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333910397018,"sku":"BWCS-NP60FU-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP60FU-1.webp?v=1778213591","url":"https:\/\/batteryweb.com\/products\/aiptek-pocketcam-8900-replacement-battery-37v-1050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
