It fits models A1709 and A1852, including MQDT2LL\/A and 26 additional regional variants. Swap it in when the original A1798 cell can no longer hold a charge or causes unexpected shutdowns.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eiPad Pro 10.5\" model variants:\u003c\/strong\u003e\n    Apple released the 10.5\" Pro across Wi-Fi and cellular SKUs sharing the same voltage rail, connector, and BMS handshake — all drawing from the same A1798 cell. One replacement battery covers the full 2017 lineup.\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 10.5\" Pro unit. The BMS communicated correctly with iPadOS at each state-of-charge threshold, and the charge IC accepted the full 8130mAh without fault flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after installation:\u003c\/strong\u003e\n    After fitting this battery, run the iPad down to automatic shutoff, then charge uninterrupted to 100% without using the device. This gives the fuel gauge IC a clean reference point against the new cell and corrects the percentage drift that commonly appears 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\"\u003eiPad Pro 10.5\" shutting down at 15–25% remaining\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the display backlight and Wi-Fi radio draw simultaneously, causing a voltage sag that the fuel gauge reads as a cutoff threshold even though reported percentage is still above zero. The original cell develops this cliff as it ages — its internal resistance rises, and the voltage drop under combined load becomes steep enough to trigger a shutdown. A fresh cell with lower internal resistance eliminates the sag. After installation, one full discharge-to-shutoff cycle lets the BMS map the new cell's actual discharge curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eiPad showing wrong battery percentage after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC inside the iPad was calibrated against the old cell's charge curve. When a new cell goes in, the IC is still using stale reference data, so it reports inaccurate percentages — often jumping or plateauing at specific points. This is not a fault with the replacement cell. Run one complete cycle: discharge to automatic shutoff, then charge uninterrupted to 100%. After that cycle, the IC recalibrates and percentage reporting stabilises.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425853997146,"sku":"BWCS-IPA179SL-1","price":48.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425854029914,"sku":"BWCS-IPA179SL-2","price":56.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425854062682,"sku":"BWCS-IPA179SL-3","price":62.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IPA179SL-1.webp?v=1779929951","url":"https:\/\/batteryweb.com\/products\/apple-ipad-pro-105-replacement-battery-377v-8130mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
