When troubleshooting charging issues, I would do the following (in order):
# Always try another Lightning cable and charger, preferably Apple original or MFi certified units.
-
# The [https://en.wikipedia.org/wiki/Lightning_(connector)|Lightning cable 8-pin connector] should be sitting flush with the housing and completely inserted. If it is not, there could be lint/dust/debris inside the port impeding a proper connection. You can clean it out with a toothpick, fine point tweezers or a dental pick. Just be careful not to damage the pins inside the Lightning Port.
-
# Change the battery. The battery is the weakest link in the entire device and certainly for charger related issues - especially on older devices that still have the original battery. Please let us know what voltage you measured at the battery. The iPad requires pretty high voltage to boot properly.
-
# If the battery is in good condition, you can use a [https://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=USB+Ammeter|USB Ammeter] to determine if the device is really drawing current when it connected to a charger. If it isn't drawing current, then I would change the Lightning/Charge Port.
-
# If a new battery and charge port still don't resolve the issue, then you either have faulty replacement parts (possible) or a logic board issue. There is an IC (commonly referred to as Tristar) responsible for communicating with the charging device and uncertified chargers can damage it. Unplug the battery and connect a known-good (preferably Apple original or MFi) charger to the device. A properly working device will show an Apple logo and boot loop. If the Tristar IC is bad then the device will not do anything.
