It fits the portable hotspot unit that shares cellular data over Wi-Fi with connected devices. Capacity is sourced from the product specification — 2600mAh at 9.62Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e4G Router platform fit:\u003c\/strong\u003e\n    The Verizon 4G Router runs a combined modem and Wi-Fi radio load off a single 3.7V cell. Both draw from the same rail simultaneously, so the battery must handle sustained dual-radio current without the BMS tripping on a false low-voltage event.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell under simultaneous modem and Wi-Fi load at maximum connected clients. The BMS held voltage above cutoff threshold throughout and did not flag overcurrent on connection spikes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eVentilation during extended sessions:\u003c\/strong\u003e\n    Keep the hotspot in an open, ventilated spot during long sessions. When connected clients are distant, the cellular radio runs at peak output power — that heat transfers directly into the battery housing and accelerates cell degradation over time.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMobile hotspot dropping connected devices mid-session on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new battery can still cause mid-session disconnects if voltage sags under peak combined load. When the modem hits a congested cell tower and ramps output, it pulls a sudden current spike on the same rail the Wi-Fi radio is already using. If the BMS reads a momentary voltage dip below its cutoff threshold — typically around 3.0V — it shuts down to protect the cell. The fix is to reduce the number of active connected clients or move the hotspot closer to the router or window to reduce radio output demand.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHotspot not powering on after sitting in a drawer\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage — around 1–2% per month under normal conditions, faster if stored warm. If the hotspot sat unused for several months, the cell may have dropped below the minimum boot voltage, typically 3.0–3.2V. At that level the BMS locks out the device to prevent deep-discharge damage. Connect the hotspot to the original charger and leave it for at least 30 minutes before attempting to power on — most BMS circuits require a trickle charge to 3.2V before they re-enable the output rail.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377834393690,"sku":"BWCS-MFT114SL-1","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377834426458,"sku":"BWCS-MFT114SL-2","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377834459226,"sku":"BWCS-MFT114SL-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MFT114SL-1.webp?v=1778773879","url":"https:\/\/batteryweb.com\/products\/verizon-4g-router-replacement-battery-37v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
