It fits the MR-102N directly, restoring power to the device when the original battery no longer holds a usable charge. Capacity figure is sourced from the product specification — 1800mAh at 3.7V nominal, 6.66Wh total.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMR-102N fit:\u003c\/strong\u003e\n    The MR-102N draws on a single-cell 3.7V Li-ion configuration to power both the cellular modem and the Wi-Fi radio simultaneously. This battery matches that voltage rail and physical footprint — 52.76 × 35.35 × 11.16mm — so it seats correctly and connects to the BMS without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell under combined modem-plus-radio load at maximum connected devices. The BMS held cutoff thresholds correctly at both ends of the discharge curve and did not trip under the start-up surge the cellular modem pulls at initialisation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eVentilation during long sessions:\u003c\/strong\u003e\n    Keep the MR-102N on an open, flat surface during extended use. When connected devices are at range limit, the cellular radio pushes to maximum output power — that sustained draw raises internal cell temperature faster than short-burst use does.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the MR-102N drops all connected devices mid-session\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe MR-102N runs two power-hungry radios at once — the cellular modem and the 2.4GHz Wi-Fi broadcast. When multiple devices are connected and the cellular signal is weak, both radios push to maximum output simultaneously. That combined draw creates a voltage sag on the cell that the BMS reads as an undervoltage condition, triggering a momentary cutoff. A battery with reduced capacity from age reaches that sag threshold faster, making drop-outs more frequent even during a session that starts fine.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMR-102N won't power on after sitting unused\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge at roughly 1–2% per month even with no load. After several months in storage, the MR-102N battery can fall below the minimum boot voltage the BMS requires — typically around 3.0V per cell — and the device will not respond to the power button at all. Connect the hotspot to a charger and leave it for at least 30 minutes before attempting to power on. If the charge indicator does not activate within a few minutes of connecting, the cell may have dropped below the BMS recovery threshold; in that case, apply charge in short intervals and check for the indicator light at the 5-minute mark.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377889771610,"sku":"BWCS-EX6210RC-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377889804378,"sku":"BWCS-EX6210RC-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377889837146,"sku":"BWCS-EX6210RC-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EX6210RC-1.webp?v=1778773918","url":"https:\/\/batteryweb.com\/products\/aximcom-mr-102n-replacement-battery-37v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
