It fits directly in place of the OEM part 58-000280 \/ 2955C7. If your tablet no longer holds a charge or dies before the percentage reaches zero, this replacement restores full cell capacity.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e9th Gen HD 10.1 fit (M2V3R5):\u003c\/strong\u003e\n    The 9th generation HD 10.1 uses a specific connector orientation and BMS handshake tied to the 58-000280 cell spec. This replacement matches that voltage rail and connector so the charge IC communicates correctly with the new cell from the first boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the HD 10.1 9th gen board. The BMS accepted the cell without fault flags, and the charge IC reached termination voltage cleanly at 4.35V without triggering a thermal cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge reset after install:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge to automatic shutoff, then charge uninterrupted to 100%. This forces the fuel gauge IC to recalibrate against the new cell's actual capacity curve and clears the inaccurate percentage readings that commonly appear after a swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTablet shutting down at 15–25% remaining after battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC was calibrated to the old, degraded cell. The new cell has a steeper voltage curve near the bottom of its range, and the gauge misreads that drop as a critical low-battery threshold. When the display and WiFi pull simultaneous load, the combined draw accelerates the voltage drop past the shutdown threshold before the percentage reflects it. Run one full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% — this re-anchors the gauge to the new cell's actual voltage endpoints.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging not available after replacing the HD 10.1 battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Fire HD 10.1 uses a proprietary charge negotiation sequence between the charge IC and the battery cell. On a freshly installed cell, the charge controller may default to standard 5W input until it completes one accepted full charge cycle. Use the original Amazon power adapter — third-party USB-PD chargers can stall negotiation entirely on this device. After one complete charge cycle with the OEM adapter, fast charge typically resumes at the expected input rate.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425830010970,"sku":"BWCS-ABD102SL-1","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425830043738,"sku":"BWCS-ABD102SL-2","price":48.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425830076506,"sku":"BWCS-ABD102SL-3","price":53.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ABD102SL-1.webp?v=1779929902","url":"https:\/\/batteryweb.com\/products\/amazon-kindle-fire-hd-101-9th-replacement-battery-38v-6300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
