It replaces OEM part numbers NP-900, 02491-0015-00, BATS4, and 02491-0037-00. The cell fits the CS 6531-N body directly and communicates with its battery management system over the standard NP-900 contact layout.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCS 6531-N fitment:\u003c\/strong\u003e\n    The NP-900 form factor — 43.70 × 31.30 × 7.00mm — is specific to this compact camera platform. The three-contact terminal arrangement carries both power and the signal line the camera body uses to read charge state. A cell outside this exact footprint will not seat correctly in the battery bay.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the CS 6531-N body using the OEM charger. The BMS handshook on first charge without prompting a compatibility error, and the charge-state indicator tracked the discharge curve through to cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on the CS 6531-N:\u003c\/strong\u003e\n    Run one full charge cycle inside the camera body before your first shoot. The CS 6531-N maps its battery-remaining display to a charge curve it records during that initial cycle — skipping it can cause the indicator to read inaccurately for several sessions afterward.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash recycling slowing down toward end of charge on the CS 6531-N\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe CS 6531-N flash capacitor draws a concentrated burst of current each time it recharges between shots. As cell voltage drops below roughly 3.5V, the available current for capacitor recharge decreases noticeably. The result is a longer wait between flashes — not a fault in the cell itself, but a natural consequence of the discharge curve. If recycling time is increasing, check the battery-remaining indicator; the cell is likely in its final 15–20% of capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping on the display after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe CS 6531-N reads remaining charge by mapping current cell voltage against a stored discharge curve. A new cell's discharge curve can differ slightly from the OEM cell the camera calibrated against, causing the indicator to jump — for example, dropping from 80% to 50% without warning. This is a display calibration issue, not a cell fault. Perform two full charge-and-discharge cycles inside the camera body; the indicator typically stabilises as the BMS updates its internal reference points.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333825757274,"sku":"BWCS-NP900-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333825790042,"sku":"BWCS-NP900-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333825822810,"sku":"BWCS-NP900-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP900-1.webp?v=1778213259","url":"https:\/\/batteryweb.com\/products\/acer-cs-6531-n-replacement-battery-37v-600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
