简介
Follow this guide to replace the battery in your iPad Pro 12.9" 4th generation.
This guide is written with an A2229 (Wi-Fi only) model iPad Pro. If you have the cellular model, use this guide as a general reference, but you may need to perform extra disassembly not covered in this guide.
Some photos show the battery connector blocked with two card strips. While this is an optional method, it's more reliable to fully discharge the battery. Ignore this visual discrepancy as you work through the guide.
If your battery is swollen, take appropriate precautions.

Is there a way to test the battery with a multimeter before removing all the components?
(Mine is unresponsive and I’m trying to trouble shoot components)
Hey D Sully,
Apple definitely hid a lot of the exposed contacts in this iPad. To reach the contacts on the battery connector, you need to get underneath the connector on the logic board.
There could still be ways to troubleshoot your iPad without opening it. If you haven't already, try force restarting it, plugging it into power for over a minute, trying a different charger, etc. If you do opt to open it, check the screen connectors, as well.
If the probes on your multimeter are sufficiently small, you might be able to remove just the lower components from the logic board (including the four screws securing it to the frame) and slightly lift it to gain access to the battery contacts. We don't recommend this as, it risks damaging the board.
Whatever routes you choose, good luck and feel free to post back here with any results!
