It fits the B1501 OEM part number and slots directly into the 874FT chassis. If your original battery no longer sustains a hotspot session through normal daily use, this is the correct replacement cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e874FT platform fit:\u003c\/strong\u003e\n    The 874FT runs a combined cellular modem and Wi-Fi radio off a single 3.8V cell. Both radios share the same power rail, so voltage tolerance and connector polarity must match exactly. This battery meets those spec requirements.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell under simultaneous modem and Wi-Fi load. The BMS held stable output without triggering low-voltage cutoff under multi-device connection stress.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eVentilation during extended sessions:\u003c\/strong\u003e\n    Keep the 874FT on a hard, flat surface — not a cushion or bag pocket — during long hotspot sessions. When connected devices are far from the hotspot, the cellular radio runs at full output power. That extra heat sits directly on the battery if airflow is blocked.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the 874FT disconnects users mid-session under full load\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the 874FT is serving the maximum number of connected devices, both the LTE modem and the Wi-Fi radio draw peak current simultaneously. This combined load pulls the 3.8V cell harder than any single-radio scenario. If the cell has aged or is partially discharged, voltage sags below the BMS cutoff threshold and the device resets — dropping all connected users. A fresh, fully charged cell eliminates that sag margin issue.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003e874FT won't power on after sitting unused for several weeks\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge slowly during storage. If the 874FT sits unused long enough, the battery drops below the minimum boot voltage — typically around 3.0V for a 3.8V nominal cell. At that level, the device shows no response to the power button. Connect the hotspot to a charger for at least 15–20 minutes before attempting to power on; most BMS circuits need to detect a minimum charge threshold before they allow the device to boot.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377823187034,"sku":"BWCS-ZDW670SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377823219802,"sku":"BWCS-ZDW670SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377823252570,"sku":"BWCS-ZDW670SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZDW670SL-1.webp?v=1778773896","url":"https:\/\/batteryweb.com\/products\/mtc-874ft-replacement-battery-38v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
