It replaces the original cell when capacity has dropped or the battery no longer holds a charge. Dimensions are 40.00 × 31.10 × 5.90mm — matching the original form factor for the battery compartment door to close correctly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDC 7XS and DC 8XS compatibility:\u003c\/strong\u003e\n    Both models run the same 3.7V battery rail and share an identical battery bay geometry. One cell covers both cameras without modification or adapter.\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 a camera body to confirm BMS acceptance and stable voltage delivery across the full discharge curve. No cutoffs were triggered during normal photo and video capture.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle:\u003c\/strong\u003e\n    Insert the battery and charge it fully inside the camera body or OEM charger before shooting. Some compact camera BMS systems only calibrate the battery-remaining indicator after completing one full charge cycle from within the camera body itself.\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 Revue DC 7XS maps its battery indicator to voltage thresholds tuned for the original cell's discharge curve. A new third-party cell can present a slightly different curve, causing the indicator to read empty while usable charge remains. This is a display calibration issue, not a cell fault. Run one full charge-to-discharge cycle inside the camera body to let the BMS remap its thresholds to the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically across the shot count display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eErratic percentage readings on the DC 7XS typically occur when the camera's fuel gauge has not yet mapped the new cell's mid-range discharge slope. The original cell's voltage-to-percentage table is stored in firmware and may not align with a replacement cell until recalibrated. Let the battery drain from 100% to camera cutoff in one session without interruption. After one full cycle the readings stabilise — cutoff on this camera occurs at approximately 3.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333859573850,"sku":"BWCS-LI40B-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333859606618,"sku":"BWCS-LI40B-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333859639386,"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\/revue-dc-7xs-replacement-battery-37v-660mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
