It uses the OEM part number 21700-1S1P and fits directly into the AB2L housing. Capacity figure is taken from the product data: 5000mAh \/ 18.5Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAB2L platform fit:\u003c\/strong\u003e\n    The AB2L runs a single 21700-format lithium cell at 3.7V nominal. The BMS in this camera monitors cell voltage directly — no multi-cell balancing required. This replacement matches that voltage rail and uses the same cylindrical 21700 form factor the camera's contact plate expects.\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 sustained IR LED draw overnight. The BMS held the low-voltage cutoff at the correct threshold and resumed normal operation after recharge without requiring a manual reset.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install power cycle:\u003c\/strong\u003e\n    After fitting this battery, power cycle the camera once through the 360 app. The firmware needs to register the new cell before motion recording logs correctly to cloud storage — skipping this step can cause missed clips on the first motion event.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera going offline in the 360 app after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSwapping the battery cuts power to the camera's WiFi module, which drops the active session token. The app loses the device registration and marks it offline even after the camera boots back up. To fix this, open the 360 app, go to device settings, and trigger a manual reconnect or re-pair the camera to your network. The camera does not rejoin automatically on some firmware versions — the reconnect step is required.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eApp displaying 0% or a frozen percentage after installing a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe AB2L uses a voltage-threshold indicator, not a fuel gauge IC. When a new cell goes in at a voltage the camera has not seen before, the indicator can misread it as empty or lock onto a stale reading. Run one full charge cycle — charge to 4.2V, then let the camera draw the cell down through normal use. After that single cycle the percentage reading will track the actual cell voltage correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377747361882,"sku":"BWCS-FST200SL-1","price":43.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43377747394650,"sku":"BWCS-FST200SL-2","price":51.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43377747427418,"sku":"BWCS-FST200SL-3","price":56.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FST200SL_1.webp?v=1778771922","url":"https:\/\/batteryweb.com\/products\/360-ab2l-replacement-battery-37v-5000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
