I bought my iPad and Apple Pencil in September. Within the last week, my pencil will not charge. It will stay connected to my iPad, but just wont charge. At this point, it is fully dead and I have left it on the charging side of the iPad for a week.

All rechargeable batteries, regardless of battery chemistry, require maintenance through periodic charging. In this regard, the battery within the Apple Pencil is no different to any other device that is powered by an internal battery.
If your Pencil has been set-aside for an extended period, unused and uncharged, the Pencil battery may have been damaged through deep discharge. In common with all Li-ion batteries, they must always have some level of charge.
The tiny internal Li-ion battery is susceptible to permanent/irreversible damage through being left discharged for long periods. Even some “new” pencils can exhibit signs of failure out-of-the-box if they are “old stock”.
It is essential that if you have an Apple Pencil that you charge it regularly - whether used or not - so as to protect the battery from deep-discharge. Do not allow a pencil to remain in low-charge state for any period of time - as the internal battery will fail, rendering the Pencil useless. Setting aside an unused Pencil, for extended periods, is a recipe for premature death of the Pencil battery.
If the Pencil Battery has failed, the only remedy is to replace the Pencil. If the battery has failed and your pencil is within its one-year warranty, you should look to having it replaced by your retailer or at an Apple Store.
Gentle warming of the Pencil (such as placing on a hot water radiator), prior to attempting charging of the Pencil, can sometimes resurrect a dead Pencil battery.
I agree with contacting Apple. It is still in the warranty period, so if it is truly dead they should do something.
