Both devices share the same battery bay dimensions and connector, making this a single part for either unit. Capacity is 3000mAh (11.1Wh), matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSpeedbox LTE mini and LTE+ mini compatibility:\u003c\/strong\u003e\n    Both models use the same 3.7V battery rail, identical connector pinout, and the same BMS handshake protocol — the hardware difference between the two is in the modem module, not the power circuit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through charge and discharge cycles on a Speedbox LTE mini unit. The BMS engaged correctly at full load with four active client devices connected, and low-voltage cutoff triggered at the expected threshold without hard-locking the device.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCellular signal and battery load:\u003c\/strong\u003e\n    When the hotspot operates in a weak signal area, the LTE modem increases transmit power to maintain the connection. Keep the device in a location with reasonable signal strength — running at maximum transmit power continuously generates heat that accelerates cell wear.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Speedbox LTE mini drops connected devices mid-session\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Speedbox LTE mini runs two power-hungry subsystems simultaneously: the LTE modem and the 2.4GHz Wi-Fi radio. When multiple clients are active and signal quality is poor, combined current draw spikes sharply. A degraded original battery cannot sustain that draw without voltage sagging below the BMS protection floor. The BMS then cuts power to protect the cell, which the device registers as a shutdown rather than a crash — clients lose connection instantly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHotspot shows charged but won't boot after sitting unused for weeks\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells self-discharge at roughly 1–3% per month under normal storage conditions, but a battery that was already partially depleted before storage can drop below minimum boot voltage. The Speedbox LTE mini requires approximately 3.0V at the cell to initiate startup. If the battery reads below that, the device will not respond to the power button at all. Connect the hotspot to a charger for at least 20–30 minutes before attempting to power it on — this brings the cell voltage back above the boot threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377845141594,"sku":"BWCS-HUE589XL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377845174362,"sku":"BWCS-HUE589XL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377845207130,"sku":"BWCS-HUE589XL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HUE589XL-1.webp?v=1778773879","url":"https:\/\/batteryweb.com\/products\/telekom-speedbox-lte-mini-replacement-battery-37v-3000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
