It fits directly into the hotspot unit and restores full operation when the original cell has degraded. Capacity is 1500mAh (5.55Wh) — sourced to match the OEM specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMobiler WLAN HotSpot fit:\u003c\/strong\u003e\n    This hotspot runs a combined cellular modem and Wi-Fi radio off a single 3.7V cell. The replacement matches that voltage rail and physical dimensions (65.23 × 41.98 × 5.21mm), so the BMS handshake completes correctly on first boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell under simultaneous cellular and Wi-Fi load — the BMS held a stable discharge curve with no low-voltage cutoff tripping prematurely and no thermal shutdowns during sustained draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eVentilation during extended sessions:\u003c\/strong\u003e\n    Keep the hotspot on an open, flat surface when running continuous sessions. The cellular radio pushes to maximum output power when connected devices are far away, and heat trapped underneath the unit transfers directly into the cell casing.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHotspot disconnecting users mid-session on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the hotspot hits maximum client connections, the modem and Wi-Fi radio draw current simultaneously at full output. A new cell with a slightly stiff internal resistance can sag below the BMS cutoff threshold during that combined peak draw. The result looks like a Wi-Fi drop but is actually a momentary undervoltage event. Reduce connected clients by one or two and confirm the cell voltage stabilises above 3.5V under load.\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 at roughly 2–3% per month, and the TrekStor hotspot draws a small standby current even when switched off. After several months in storage, the cell can drop below the 3.0V minimum boot threshold the BMS requires to release current to the board. Plug the unit into its charger and leave it connected for at least 20–30 minutes before attempting to power on — this lets the charger trickle the cell back above the BMS re-initialisation voltage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377849106522,"sku":"BWCS-SBX150RX-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377849139290,"sku":"BWCS-SBX150RX-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377849172058,"sku":"BWCS-SBX150RX-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SBX150RX-1.webp?v=1778773940","url":"https:\/\/batteryweb.com\/products\/trekstor-mobiler-wlan-hotspot-replacement-battery-37v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
