After a few months of no use, I tried to charge and use my apple pencil 2. It won't charge, but still connects to my iPad Pro. Both are under a year old, purchased in January 2020. The pencil worked for a bit, and then quit, but never showed a charge over 0%...any idea why this might be happening?
You're very first statement explains what the issue is. The reality is the battery in Apple Pencil is teeny/tiny and if not kept charged for an extended period of time dies and cannot come back to life. If the pencil is still within its one year warranty, Apple will replace it. If it is older than a year, you'll have to buy a new one. Either way, do NOT let the battery remain uncharged.

Expanding upon the sage advice and information provided by lobsterghost1, it is essential that a second generation Apple Pencil is docked with the iPad Pro whenever it is not being used - as doing so both optimally maintains the Pencil Battery - and protects it from damage due to deep discharge, a condition from which it cannot recover.
Setting aside a Pencil, unused/uncharged for an extended period, will result is irreversible battery damage.
