microsoft surface pen is my touchstone for this. the only way i could get new batteries was online and the pen lasted for so long if i bought a pack of 4 batteries i’d have lost the other two but the time they ran or so id need to but a whole new pack.

I’m fairly certain you can take apart most 9 volt batteries to get at the AAAA batteries inside
