Battery issues with new battery.
Hi, recently I’ve got my hands on an old iPad Air first Gen with what I assumed was dead battery. It showed battery charging icon on screen on charger, but never charge enough to turn on. I've tried restarting the device, even dfu restore, but nothing worked. After some googling, I've tried restarting the iPad many times (about 30) when it finally came on. Coconut Battery showed me that the health of battery is 8%.
So I've ordered the new one. Exchange went good, even though it was difficult.
Imagine my surprise, when I've assembled the iPad and finded out, that new battery with about 30% won't charge, and that device would restart, when charger is connected (with charger disconnected, iPad won't restart by itself). It shows that it is charging, but it isn't.
Any ideas?
