It fits the Kindle 3 Wi-Fi and Kindle 3G variants, all sharing the same battery footprint and connector. Dimensions are 96 × 67 × 4mm — confirm clearance before installing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eKindle 3 platform fit:\u003c\/strong\u003e\n    The Kindle 3, Kindle III, Kindle 3 Wi-Fi, and Kindle 3G all use the same battery bay, connector pin-out, and BMS handshake. One cell covers the full Kindle 3 generation without modification.\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-discharge cycle on a Kindle 3 unit. The BMS accepted the new cell without fault flags, and the firmware cycled through its calibration pass on the first full charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap charge cycle on the Kindle 3:\u003c\/strong\u003e\n    After fitting this cell, connect via USB and let it charge completely before switching the device on. Kindle 3 firmware recalibrates the battery percentage display during that first full charge — skipping it leaves the indicator inaccurate for days.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Kindle 3 shows a low battery warning immediately after a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eReplacement Li-Polymer cells ship at storage voltage — typically 3.6–3.85V, which sits below the Kindle 3's firmware threshold for a \"full\" reading. The device sees an unrecognised charge state and throws a low battery warning even though the cell is not flat. This is a firmware calibration issue, not a faulty battery. Connect to USB and charge fully before first use — the warning clears once the cell reaches 4.2V and the firmware logs a complete cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eKindle 3 battery percentage jumping around after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Kindle 3 estimates state-of-charge by tracking voltage curves it learned from the old, degraded cell. After a swap, those learned curves no longer match the new cell's discharge profile, so the percentage gauge jumps — sometimes dropping 20% suddenly then recovering. The firmware corrects this by running two or three full charge-discharge cycles to relearn the curve. Run the battery down to the auto-shutdown point, then charge fully, twice — the percentage display stabilises after that.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360268779610,"sku":"BWCS-ABD003SL-1","price":16.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360268812378,"sku":"BWCS-ABD003SL-2","price":18.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360268845146,"sku":"BWCS-ABD003SL-3","price":20.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ABD003SL-1.webp?v=1778611048","url":"https:\/\/batteryweb.com\/products\/amazon-kindle-3-replacement-battery-37v-1900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
