It replaces OEM part W-10 and restores power to units where the original cell has degraded or failed. Capacity figure is taken directly from product specifications at 18.5Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eM1 and MR1100 fitment:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions, connector pinout, and BMS handshake protocol — the W-10 cell works across both without modification or adapter.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the M1 platform. The BMS communicated charge state correctly to the hotspot firmware, and no false low-battery cutoffs were triggered under combined modem and Wi-Fi load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eVentilation during extended sessions:\u003c\/strong\u003e\n    Keep the hotspot on an open surface when running multiple connected devices. The cellular radio pushes to maximum transmit power in weak signal areas, and heat buildup against the battery shortens cell life faster than discharge cycles alone.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHotspot warm during extended sessions on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fully charged W-10 cell can still run warm when the M1 is handling six or more connected devices in a low-signal area. The modem draws peak power trying to maintain the cellular link, and that current draw heats the battery from inside the cell. This is normal behaviour under load, but sustained temperatures above 40°C accelerate capacity fade in lithium-polymer cells. Place the unit flat on a hard surface with airflow underneath — not on fabric or inside a bag — during heavy sessions.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eM1 won't power on after sitting unused for weeks\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLithium-polymer cells self-discharge over time, and the M1 firmware will not attempt to boot if the battery voltage has dropped below approximately 3.0V. The device appears completely dead — no LED, no response to the power button. Connect the hotspot to its original charger and leave it for at least 20–30 minutes before pressing the power button. If the LED does not respond at all after that period, check the charger output is reaching 5V at the cable tip before assuming the battery is the fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377829019738,"sku":"BWCS-NTG110SL-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377829052506,"sku":"BWCS-NTG110SL-2","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377829085274,"sku":"BWCS-NTG110SL-3","price":41.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NTG110SL-1.webp?v=1778773879","url":"https:\/\/batteryweb.com\/products\/telstra-m1-replacement-battery-37v-5000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
