I have try other brands, but I have always return to Energizer batteries. They last a long time and even after being a long time in an equipment I have never experience the gel like feeling of other battery as if they have melted or something.

Looked all over in many different stores for these AAAA batteries! Didn’t want to have to drive all the way into town to get them for my surface pen. So glad I decided to stop by and check if Best Buy had it. Now my pen works perfectly!

Can't believe there is a AAAA battery option. Needed for a computer stylus. Stylus up and working. BestBuy was the only store around that had this item. Ordered online and easy pickup at store.

AAAA batteries, who would have though?? better than using button batteries by a long shot. I've had great performance from Energiser batteries and these are no exception. I use them in the stylus for my laptop and I'm still on my first pair.

Used in the Surface Pro stylus. Last pretty well and only had to replace it three times before the Surface battery lost significant capacity.

The packaging was good at the store we went to, and the batteries worked as expected. It's good that Best Buy carries these because I wouldn't have liked spending a shipping fee for something so cheap. For those who need these specialty batteries, go to Best Buy.

My Microsoft Surface pen battery finally died and needed to be replaced. As AAAA sized bats are not something I keep at home, swung by to grab these. They are Energizer batteries - they worked great.

My daughter needed this battery replacement for her Microsoft pen. Works perfect. Brought her 2pks, seems like it is a hard battery to find

Great batteries, I use these in my graphic tablets pens an they last up to 6 month with daily usage.

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

It's always urgent when you need something that is hard to find. This battery if for our hotel lock system and we were badly in need of it. I expected to be out of luck and that I would need to order it but I was surprised to find that Best Buy had it in stock. Saved me.

Last long battery, good quality and pretty hard to find .

These batteries are required for my bamboo pen that I use with my laptop computer. I was surprised to find that any store had them. They also last a long time and no more cost then regular batteries.

I am SUPER GLAD best buy offers these batteries! These are used in my Microsoft Surface Tablet Pen.. Best Buy has these for the best price around and they are FRESH meaning they haven't been on the shelf for months.. I highly recommend these

I didn't realize AAAA batteries were so difficult to find. I checked all the typical retail stores with no luck. Since the battery was needed for a stylus pen, I decided to check out Best Buy and was pleasantly surprised they carried this.

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

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!!

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!

Hard to find batteries that easily fit in my stylus

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