Voniko – Premium Grade AAAA Batteries (8 Pack) – Ultra Long Lasting, 5-Year Shelf Life, Leakproof 1.5V AAAA Alkaline Battery – Perfect for Stylus Pens, Glucose and Blood Monitors, and More

I don't use a lot of AAAA batteries, so I didn't want to buy a bunch of these things. I don't have a lot of different use cases to test these, but I will post if their shelf life is significantly less than 5 years as Voniko claims.

I couldn't find AAAA at any of the local stores so I went to a specialty battery supply store and the said they would order me a set of 2 for 11 bucks, so I looked on Amazon and found these. They saved me a lot of money, and these batteries fit my HP Touchscreen Computer Pointer Pen perfectly. Thanks Amazon!

Packaging was secure; all batteries were included. Delivery to my mailbox was secure.

very hard size to find locally

Great buy

Item was brought as a replacement battery for stylus pen for microsoft surface. Easy to replace in pen and works instantly. Hard to assess for longevity as I only use the pen a couple of times per month. I replaced the battery >3 months ago and the first one is still working without incidents.

Perfect for Lenovo pen. Good price.

These are nice enough batteries and they’re well priced. That said they’re not Duracell.
