It slots in as the internal backup power source, keeping the router live during mains failures or grid-unstable deployments. OEM part number 170848-000 confirms fit across both E100 and E110 units.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eE100 and E110 shared battery platform:\u003c\/strong\u003e\n    Both models run the same 7.4V battery rail and use an identical physical connector and BMS handshake. One cell SKU covers both units — no firmware or hardware difference affects fitment.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge cycle on an E100 unit and confirmed the router's BMS accepted the new battery within the expected window. The protection circuit responded correctly to both charge termination and low-voltage cutoff events.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after installation:\u003c\/strong\u003e\n    Leave the router plugged into mains power for at least four hours after fitting this battery. The E100 and E110 firmware runs a charge-acceptance sequence before it will commit the battery to backup duty — skipping this step causes the router to report the battery as unavailable even though it physically seated correctly.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the E100 shows a battery error for up to 24 hours after swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eCradlepoint's firmware does not immediately recognise a newly installed cell as ready for emergency use. The router runs an internal validation cycle that checks cell voltage, charge state, and BMS communication before it clears the battery error flag. A fresh Li-ion cell sitting at partial state-of-charge will fail that initial check. The error clears on its own once the battery reaches a full charge and the firmware completes its acceptance sequence — no reset is required.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery self-test failing on E100 \/ E110 after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe E100 and E110 include a periodic self-test that draws a brief load from the battery and measures voltage response. If the test runs before the cell is fully charged, the voltage sag under load exceeds the firmware's pass threshold and the test logs a failure. This is not a defective cell — it is a timing issue. Allow four hours of continuous mains charging before triggering or interpreting any self-test result. A passing self-test requires the cell to hold above 7.0V under the load pulse.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333519966298,"sku":"BWCS-CPE100RC-1","price":80.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333519999066,"sku":"BWCS-CPE100RC-2","price":94.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333520031834,"sku":"BWCS-CPE100RC-3","price":104.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPE100RC-1.webp?v=1778212934","url":"https:\/\/batteryweb.com\/products\/cradlepoint-e100-lte-router-replacement-battery-74v-10000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
