Is it suitable surface Pro pen 3 ???

Yes, I purchased these for my Surface Pro 3. Two of these button cells are used for the top button to communicate via bluetooth to start OneNote. I have not had to replace these batteries yet,as the originals are still working fine. For the actual pen function an AAAA is used. Likewise I have not needed to replace the original AAAA yet and I've had my Surface Pro 3 for almost a year. Enjoy your Surface Pro 3 :)
