My Apple Pencil battery charges very slowly

I bought a refurbished apple first generation pencil for my 9th generation iPad recently and I connected it to the iPad port and it is paired and connected and Bluetooth recognises it but in one hour it has only charged 5%. It was completely flat when connected initially. Is it no good?

If an Apple Pencil is set-aside for an extended period, unused and uncharged, its battery may be irreversibly damaged through deep discharge. In common with all Li-ion batteries, they must always have some level of charge.


The Pencil's tiny internal Li-ion battery is susceptible to permanent 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. Never 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 an extended period, is a recipe for premature death of the Pencil battery.


If the Pencil Battery has failed, the only remedy is to replace the Pencil.


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.

If it's a refurbished Apple Pencil and sold by Apple themselves as such, contact Apple who can help remedy the issue. Maybe it was left sitting idle for too long and developed a battery fault due to the battery being dead for too long.


If it was sold by Amazon or a third-party, contact them.


In any case, contact Apple if it was one of their own official refurbished products, sold by Apple themselves.
