Wacom system doesn't use a battery in the pen/stylus of any version.

Are these actual N-Trig "no-bluetooth" pens eating AAAA cells? The proper N-Trig protocol (Surface 3 & later without BT and Kobo) are about 1500 hours use and 6 months to a year standby. The BT function on Surface pens (reprogamable "magic button" for OneNote etc) either uses a separate battery to the writing bit, or the entire pen is recharageable (sealed). There are two kinds of Wacom (neither has a battery, digitiser powered), Apple Pencil, N-Trig (Kobo/Surface 3 & later), Pen Alliance system, composite pens that do more than one system and probably some proprietary ones I don't know of. A particular maker may use different technology on different models (MS, Lenovo, Samsung have done that).

Did you check use by date? (should be 3 to 5 years time).

Are you somewhere very hot?

Don't leave a pen lying on a screen or close other than an official "dock" as it may keep awake.

Rechargeable AAAA are really poor, some maybe 1/5th of running time of Alkaline and cheaply made NiMH have a high self discharge rate compared to Alkaine or Lithium (which are 3.2V to 4.7V depending on type so can't replace single AAAA, AAA, AA, C, or D cells.
