It powers the camera's onboard processor, IR LEDs, and wireless module through each wake-sleep cycle. Capacity is taken directly from product data at 38.48Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDS-2XS2T46XM cell match:\u003c\/strong\u003e\n    The DS-2XS2T46XM runs its processor, PIR sensor, and IR array from a single 3.7V cell. The BMS on this camera checks cell voltage at boot — a mismatched voltage rail prevents the camera from completing its startup handshake with Hik-Connect.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through motion-trigger events and monitored BMS response during the combined IR LED and WiFi transmission spike. The cell held voltage above the BMS low-cutoff threshold across repeated short-interval triggers.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install power cycle:\u003c\/strong\u003e\n    After fitting this cell, power cycle the camera once through the Hik-Connect app. The firmware must re-register the new cell before motion events log correctly to cloud storage — skipping this step can cause the first few triggered clips to drop.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the DS-2XS2T46XM goes offline in Hik-Connect after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the original cell is removed, the camera loses its session token stored in volatile memory. On restart with the new cell, Hik-Connect no longer recognises the device session as active. The camera appears offline even though it has power and a WiFi signal. Re-adding the device in the app or triggering a soft reset through Device Management clears this and re-establishes the connection.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eApp reporting 0% or incorrect charge percentage after battery install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DS-2XS2T46XM uses a voltage-threshold indicator, not a fuel gauge IC. After fitting a new cell, the firmware has no charge history to reference and defaults to 0% or an erratic reading. One full charge-to-discharge-to-full-charge cycle gives the firmware enough voltage data points to display an accurate percentage. Until that cycle completes, ignore the percentage and confirm the cell is healthy by checking that the camera stays online and triggers normally. A fully charged cell should read at or above 4.1V at the terminals.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377766727770,"sku":"BWCS-HKD246SL-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377766760538,"sku":"BWCS-HKD246SL-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377766793306,"sku":"BWCS-HKD246SL-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HKD246SL-1.webp?v=1778772243","url":"https:\/\/batteryweb.com\/products\/hikvision-ds-2xs2t46xm-replacement-battery-37v-10400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
