Help with Battery icon diagnostics

Apple iPad 4th Gen (Wi-Fi/AT&T/GPS) 16, 32, 64, 128 GB* Specs

Identifers: iPad 4th Gen (Wi-Fi + Cellular) - MD516LL/A* - A1459 - 2605* - iPad3,5

I got this one in with a battery icon I don't know. The battery appears dead. While in the charger I can press the power button and very quickly get a battery icon (on its side) with what looks like three or four vertical red lines at the base of the battery. Is this a dead battery or does the icon tell something else?

@mayer if this is

the icon you get, then this is the icon you'll see if you plug your iPad into power, but the battery is to low for it to start. You can try and charge it for an hour or so and if everything works it should boot up. If not, then you either have issues with the charger (not the right one or not working), or you may have issues with the lightning connector. It would be unusual to display for a bad battery, but of course not impossible.

My cable works fine on other iPads. What would cause a lightning connector issue? It has been in the dock for two hours now. When I press the power button, the screen comes on shows the icon with the red lines for a second, the lines then disappear to show just a black outlined battery. It does this three times and shuts off.

Bad pins, dirt or a failed connector. Make sure you have a good charger. What type charger are you using? The 3 flashes and turning off is caused by the same issue. Not enough oomph to power up.

Known good connector. Port appears to be clean and undamaged..

Possibly that your battery is discharged below the threshold to be recharged. A higher wattage charger may be helpful. If not, start with a new battery.

I'm going to order both a battery and connector. Will update my results.
