It fits models A1566 and related variants across the WiFi and cellular configurations. Swap it in when the original cell no longer holds a useful charge or fails to power on at all.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eiPad Air 2 and iPad 6 platform fitment:\u003c\/strong\u003e\n    Both generations share the A1547 cell format — same connector pinout, same BMS handshake voltage, and the same 186.50 × 130.00 × 3.50mm footprint inside the adhesive-bonded chassis.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on iPad Air 2 hardware. The BMS accepted charge negotiation on the first cycle, held voltage stable across display and WiFi combined load, and showed no thermal events through a full depletion run.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge reset after installation:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to automatic shutoff, then charge uninterrupted to 100%. This gives the iPad's fuel gauge IC a calibration reference against the new cell and clears the inaccurate percentage display that almost always 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 Air 2 shutting down at 15–25% remaining after battery replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC is still calibrated to the old cell's voltage curve. The new cell hits a voltage cliff under combined display and WiFi load at a point the gauge hasn't mapped yet — so the iPad reads it as a hard cutoff. It's not a faulty cell. One full discharge-to-shutdown followed by an uninterrupted charge to 100% resets the reference. After that cycle, the gauge tracks the new cell's curve accurately and the early shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging unavailable on iPad Air 2 after battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe iPad's charge IC runs a USB-PD negotiation check on the first accepted charge cycle after a new cell is fitted. Until that cycle completes, the device may fall back to standard 5W charging and ignore higher-wattage adapters. Plug in a USB-PD charger and let it complete one uninterrupted charge from low to 100%. After that first full cycle, USB-PD negotiation re-establishes and fast charging becomes available again.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425936834650,"sku":"BWCS-IPA156SL-1","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425936867418,"sku":"BWCS-IPA156SL-2","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425936900186,"sku":"BWCS-IPA156SL-3","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IPA156SL-1.webp?v=1779930008","url":"https:\/\/batteryweb.com\/products\/apple-ipad-air-2-replacement-battery-38v-7300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
