It matches the OEM BP-5L specification and fits the same physical bay. Voltage and capacity are verified against the original cell before shipping.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRenkforce 1373174 fit:\u003c\/strong\u003e\n    The 1373174 runs a single-cell 3.7V rail — the BP-5L slot accepts a specific 65.80 × 43.80 × 5.30mm cell footprint with a matched connector tab. Fitting a cell outside that voltage rail causes the camera's onboard regulator to reject the supply and refuse to boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the 1373174's BMS at both idle draw and peak IR-LED activation. The BMS held charge acceptance through the full 1400mAh range without triggering an early cutoff on the motion-trigger current spike.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirmware registration on first install:\u003c\/strong\u003e\n    After fitting this cell, power cycle the camera once through the app. The 1373174's firmware must register the new cell before motion recording events log correctly to cloud storage — skipping this step causes missed clips even when the camera appears online.\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 app after battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eSwapping the cell on the 1373174 drops the board voltage to zero momentarily. That clears the active WiFi session token stored in volatile memory. The camera reconnects to the network but the app still holds the old session, so it shows the device offline even though the camera is powered. Open the app, remove the device, and re-add it — the camera will re-register and restore live view and recording schedules.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eApp reporting 0% or wrong battery percentage after installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 1373174 uses a voltage-threshold indicator, not a fuel gauge IC. It reads cell voltage at fixed intervals and maps that to a percentage — but it calibrates those thresholds against the cell it last fully charged. A new cell installed at a partial state of charge sits outside the expected voltage curve, so the indicator reports 0% or a nonsense value. Run the camera until the original low-battery alert fires, then charge fully to 4.2V — one complete cycle resets the threshold mapping.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377787076698,"sku":"BWCS-RKF137SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377787109466,"sku":"BWCS-RKF137SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377787142234,"sku":"BWCS-RKF137SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RKF137SL-1.webp?v=1778772259","url":"https:\/\/batteryweb.com\/products\/renkforce-1373174-replacement-battery-37v-1400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
