Customer Ratings & Reviews

I never heard of AAAA batteries until my surface pen went dead. After doing some research I found that it had one of these, and thankfully, Best Buy is the only one that has these. I replaced my old one and it started working immediately!!

They work well. The lady in the store helping was very kind.

These are the greatest batteries EVER!!!! And I do mean EVER!! Seriously, these batteries are needed for the pen on a Microsoft Surface. I can not find 4-A (yes, AAAA) anywhere beside Best Buy. Thanks for having them in stock!

I use these for my Microsoft Surface Pens. The other brands (i.e. Insignia) was drained within a few days whereas Energizer lasts months as does Duracell.

I bought this so I could replace the batteries in my Surface Pro Pen, and have a spare in my laptop case. They last quite long in these pens so it will be a while before it gets replaced.

I have a Microsoft Surface Pro and my pen started acting up. I never knew it had a battery inside. Well needless to say it contains a AAAA battery. Best Buy had it. It now works great again. I bout a spare as a backup

I got this battery for my pen, works perfectly. Just a replacement.

Great battery for a stylus. Seem to last a long time even with every day use.

Worked like a charm. I love Energizer and the life of their batteries.

Its energizer batteries- OHHH now I remember!! For my surface pro pen. Yeah. These last. Now if I could just remember where I left the surface pro pen....

Perfect for HP laptop/tablet (2-in-one) stylus. Worked as expected. Thanks best buy!

Hard to find batteries that easily fit in my stylus

They managed to last for years in my pens so that was good enough for me

Looked locally all over for an AAAA battery for my stylus, but could not find it anywhere. Tried Best Buy and they had it. It saved me a 30 minute drive to a computer store. I was surprised other office stores don't stock these batteries.

Only place i can find this size batteries for my computer pen

Overall good. I did not cause any issue with my surface pen and works fine

what can I say? BB asked me to review these batteries. AAAA batteries are hard to find, but Best Buy had them. Needed for the electronic computer stylus. Everything has batteries these days!

I purchased these for the stylus pen for a Surface Pro 3 that my wife and I both share as we are both in school this pen that uses the batteries gets used alot and have lasted about if not over a year each time we change them.

I bought these AAAA bateries for my Sirface pen. This is a second purchase. The previous one lasted for 2 years. Hope to have this one longer.

Purchased these batteries to put in pen for Surface. This is the first time I had to replace this battery in several years.
