It replaces OEM part numbers 02491-0028-01 and BT.8530A.001. Slot it into either camera body using the original battery door — no modifications needed.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCR-8530 and CP-8531 compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions, voltage rail, and connector pinout. One cell covers both cameras without any wiring or adapter changes.\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 camera hardware, verified BMS handshake on first installation, and confirmed the charge indicator responds correctly through the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle on the CR-8530:\u003c\/strong\u003e\n    Insert the new cell and run a full charge through the camera body or the original Acer charger before your first shoot. The CR-8530 BMS maps its battery-remaining display against a learned charge profile — skipping this step can cause the indicator to read inaccurately for the first few sessions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the CR-8530 shows a dead-battery icon on a freshly charged replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe CR-8530 reads battery state by mapping terminal voltage against a stored discharge curve. A new cell that hasn't completed a charge cycle inside the camera body can present a resting voltage the BMS misreads as depleted. This is a calibration mismatch, not a faulty cell. Charge the battery fully inside the camera before shooting and the icon clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the CR-8530 display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eErratic percentage readings happen when the camera's fuel-gauge algorithm is still mapping its thresholds to the new cell's discharge curve. The original cell trains the BMS over hundreds of cycles — a fresh replacement resets that learned profile. Run two full charge-to-discharge cycles through the camera body and the percentage steps will stabilise. After the second cycle, the indicator should track smoothly from 100% down to the low-battery cutoff at approximately 3.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333842763866,"sku":"BWCS-PRD8330-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333842796634,"sku":"BWCS-PRD8330-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333842829402,"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\/acer-cr-8530-replacement-battery-37v-1250mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
