Amazon Basics 4-Pack AAAA Alkaline High-Performance Batteries, 1.5 Volt, 3-Year Shelf Life

Did not even know AAAA batteries were a thing until they were needed for a device lol! These worked great and have lasted so far very well!

Works like it is supposed to. Can't tell how good the battery life is since it depends on how much the pen is being used. Good price, can't complain

Used these for my tablet pen and they work really well. They last approximately maybe 3 weeks but may be different depending on the pen but overall they do the job really well and that’s all I need!!

Great price for these little batteries used for tablet pens. I was shocked when I realized there was a quadruple battery size. The four pack will last you forever because the batteries go for so many months. If they sold them in Cinco packs for less, I think it would be better keeping these in a drawer for years is no good.

These are good rechargeable batteries. I bought these for one of my kids' technology items. He has used the batteries for about 2 years. before they started losing their charging life.

Hard to find batteries in a store, so easy to find here. They work great for my flashlight. They last long and provide enough power for the flashlight to be bright.

I bought these a long time ago. I use them for the windows surface book 2 pencil. You only need one battery to power it. I haven't used the pen as much to see how long the charge last. I am hoping it will last for a while. It is a small battery but that is the only ones that will fit into that pencil. Overall I think I may have gotten a good deal out of this.

Great price for this amount of batteries that work just as well as the name brands.
