It fits the SVP XTHINN-8363, A-10, Z-10, and DC-12Z compact digital cameras. Voltage and connector match the original cell exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXTHINN-8363, A-10, Z-10, and DC-12Z compatibility:\u003c\/strong\u003e\n    All four models share the same battery bay geometry, 3.7V nominal rail, and BL-058 connector footprint. The BMS in each body reads cell voltage via the same contact arrangement, so one cell works across the entire group.\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 the bench and monitored BMS handshake and cutoff behaviour. The protection circuit engaged at expected low-voltage thresholds, and the cell accepted a full charge without thermal event.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle on SVP compact bodies:\u003c\/strong\u003e\n    Insert the cell and charge it fully inside the camera body before your first shoot. Some SVP compact BMS firmware maps the battery-remaining display against a charge profile it builds during that first in-body cycle — skipping it can cause the indicator to read inaccurately from the start.\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 partially charged BL-058 replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSVP compact bodies use a stepped voltage-threshold system to estimate charge level. A new third-party cell's discharge curve can sit slightly outside the voltage points the firmware expects, causing the indicator to drop to zero before the cell is actually empty. This is a calibration issue between the camera's lookup table and the new cell — not a fault with the cell itself. Run two or three full charge-discharge cycles through the camera body to let the BMS recalibrate its threshold mapping.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera body displaying \"no battery\" or refusing to power on with new cell installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the camera's BMS authentication check doesn't complete on the first insertion — it's a contact initialisation issue, not a dead cell. Remove the battery, clean the three contact pads on the cell and in the bay with a dry cloth, then reinsert firmly. If the body still won't power on, place the cell in the camera and connect the USB charge cable for 30 seconds before attempting to power on again. That brief charge current is enough to wake a deeply discharged cell above the BMS acceptance threshold of approximately 3.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333859999834,"sku":"BWCS-LI40B-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333860032602,"sku":"BWCS-LI40B-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333860065370,"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\/svp-xthinn-8363-replacement-battery-37v-660mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
