It fits the same physical footprint at 115.44 x 99.20 x 2.42mm and connects to the same charge IC and fuel gauge circuit. Use this when the original cell no longer holds a charge or shuts the tablet down early.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eKindle Fire HD 10 and 10.1 compatibility:\u003c\/strong\u003e\n    Both generations share the ST10 battery platform — same voltage rail, same connector pinout, and the same BMS handshake with Amazon's charge controller. OEM part numbers ST10, ST10A, 58-000119, and 26S1008 all cross to this cell.\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 a Kindle Fire HD 10 unit. The BMS accepted charge negotiation on the first cycle without tripping low-voltage lockout, and the fuel gauge IC tracked state-of-charge without error flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap fuel gauge reset:\u003c\/strong\u003e\n    After installation, run the tablet down 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 display that commonly appears after a battery swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eKindle Fire HD 10 shutting down at 15–25% remaining\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Kindle Fire HD 10 drives a high-resolution display and maintains a WiFi connection simultaneously. Under that combined load, the battery voltage drops faster than the fuel gauge expects — especially with an aged or freshly swapped cell. The charge IC reads a voltage cliff and triggers a protective shutdown before the displayed percentage reaches zero. One full recalibration cycle — full discharge to shutoff, then a full uninterrupted charge — teaches the fuel gauge the new cell's voltage-to-capacity curve and typically resolves this.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging not available after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAmazon's charge controller uses a proprietary negotiation sequence to enable fast charging on the Kindle Fire HD 10. A new cell starts the first cycle in a conservative trickle-charge state while the charge IC confirms cell impedance and BMS handshake. This is expected behaviour, not a fault. Fast charge typically becomes available after the first full accepted charge cycle — use the original Amazon power adapter and cable, not a third-party charger, to ensure the negotiation completes correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425958789210,"sku":"BWCS-ABD870SL-1","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425958821978,"sku":"BWCS-ABD870SL-2","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425958854746,"sku":"BWCS-ABD870SL-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ABD870SL-1.webp?v=1779930008","url":"https:\/\/batteryweb.com\/products\/amazon-kindle-fire-hd-10-replacement-battery-37v-3800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
