It fits the MiFi2200 portable Wi-Fi unit that shares a cellular data connection across multiple devices. Voltage and capacity match the original spec exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMiFi2200 fit:\u003c\/strong\u003e\n    The MiFi2200 runs a single-cell 3.7V Li-ion pack with OEM part references 40115114.00, 3-1826107-9, and L01478001. All three numbers trace back to the same cell configuration and connector footprint used in this hotspot generation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through combined modem and Wi-Fi load conditions. The BMS held stable cutoff at the low-voltage threshold without false trips, and the pack charged cleanly to 4.2V termination under the MiFi2200's onboard charge circuit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCellular radio heat management:\u003c\/strong\u003e\n    Keep the MiFi2200 on an open surface during extended sessions. When connected devices are far from the hotspot, the cellular radio runs at maximum output power — the extra heat generated directly at the battery 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\"\u003eWhy the MiFi2200 drops all connected clients mid-session\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe MiFi2200 runs two power-hungry subsystems simultaneously — the cellular modem and the Wi-Fi radio. At maximum client connections, combined current draw can pull the battery voltage down sharply. If the pack is aged or partially charged, this sag can breach the BMS low-voltage cutoff, causing an abrupt shutdown that drops all clients. A fresh cell with stable internal resistance maintains voltage above the cutoff threshold even under peak load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMiFi2200 not powering on after sitting unused\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the MiFi2200 sat unused for several months, the battery may have dropped below the minimum boot voltage — typically around 3.0V for this cell chemistry. The device needs enough voltage to initialise its firmware before the charge circuit can top it up, so it appears completely dead rather than just low. Connect the hotspot to a charger and leave it for 20–30 minutes before attempting to power it on; most units resume normal boot once the cell recovers above 3.2V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377888919642,"sku":"BWCS-MF2200RC-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377888952410,"sku":"BWCS-MF2200RC-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377888985178,"sku":"BWCS-MF2200RC-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MF2200RC_1.webp?v=1778773919","url":"https:\/\/batteryweb.com\/products\/novatel-wireless-mifi2200-replacement-battery-37v-1050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
