It restores power to photo and video capture functions when the original cell has degraded. Capacity is 2.44Wh — identical to OEM spec.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRCP-7325XS \/ X-8 \/ XS series fit:\u003c\/strong\u003e\n    These models share the same DS5370 cell format — same voltage rail, same contact orientation, and the same slim 5.90mm cell depth. One cell covers the full lineup without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a Rollei-compatible body. The BMS accepted the cell without rejection flags, and voltage held stable across the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle on Rollei compact bodies:\u003c\/strong\u003e\n    Insert the new cell and run one full charge cycle through the OEM charger or camera body before shooting. Some Rollei compact BMS systems need this cycle to calibrate the battery-remaining indicator — skipping it can cause the display to read inaccurately from the first shot.\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 showing on a freshly charged DS5370 replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eRollei compact bodies map battery-remaining percentage against a learned discharge curve from the previous cell. A new DS5370 cell has a slightly different resting voltage profile, so the camera can misread state-of-charge on first use. The indicator may jump to empty even when the cell is at 4.1V or above. One full charge-discharge cycle inside the camera body resets the threshold mapping and brings the indicator back in line.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically mid-shoot\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis usually appears when the camera body is reading voltage-drop events under flash or continuous AF load as a hard capacity drop. The DS5370 cell's 660mAh capacity means short high-current draws — flash recharge, autofocus motors, image stabilisation — pull a measurable voltage sag. The BMS interprets that sag as a lower state of charge and updates the indicator accordingly. Let the cell rest at idle for 10–15 seconds and the display will correct itself; if it does not, the cell may be sitting below 3.6V and needs a full recharge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333859410010,"sku":"BWCS-LI40B-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333859442778,"sku":"BWCS-LI40B-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333859475546,"sku":"BWCS-LI40B-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LI40B-1.webp?v=1778213291","url":"https:\/\/batteryweb.com\/products\/rollei-rcp-7325xs-replacement-battery-37v-660mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
