It fits directly into the CPE2000B and restores the power capacity lost when the original cell degrades. Voltage and capacity match the OEM specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCPE2000B platform fit:\u003c\/strong\u003e\n    The CPE2000B runs a combined modem-plus-WiFi load off a single 3.8V cell. This battery matches that voltage rail and the physical footprint (73.60 × 46.00 × 9.00mm), so the BMS handshake initialises correctly on first boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell under a simulated multi-device load — modem transmitting and WiFi broadcasting simultaneously. The BMS held the discharge curve without tripping and recovered cleanly from a low-state-of-charge condition.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eVentilation during extended sessions:\u003c\/strong\u003e\n    Keep the CPE2000B in an open, ventilated spot when running it for long periods. When connected devices are far from the router, the cellular radio boosts to maximum output power — sustained RF transmission generates heat that accelerates cell wear faster than any other operating condition on this device.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the CPE2000B drops connections mid-session under full client load\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the CPE2000B is serving multiple clients at once, the modem and WiFi radios draw current simultaneously. An aged or partially degraded cell cannot sustain that combined load without voltage sagging below the BMS protection threshold. The BMS interprets that sag as a fault and cuts output to protect the cell — which the connected devices see as a sudden disconnect. A fresh 4800mAh cell at full charge maintains the voltage headroom needed to absorb those combined peak draws without triggering a cut-off.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCPE2000B won't boot after sitting unused for several weeks\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells self-discharge slowly during storage. If the CPE2000B sat unused long enough, the cell voltage may have dropped below the minimum boot threshold — typically around 3.0V for this chemistry — and the device will show no response when the power button is pressed. Plugging in the charger and leaving it for 15–20 minutes lets the BMS trickle enough charge into the cell to cross the boot voltage floor. If the device still does not respond after that period, check that the charger output is delivering the correct voltage at the connector before replacing any components.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377787273306,"sku":"BWCS-VIC200SL-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377787306074,"sku":"BWCS-VIC200SL-2","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377787338842,"sku":"BWCS-VIC200SL-3","price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VIC200SL_1.webp?v=1778772259","url":"https:\/\/batteryweb.com\/products\/vida-cpe2000b-4g-lte-cpe-router-replacement-battery-38v-4800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
