Customer Ratings & Reviews

This battery works just like any other battery one would purchase; just smaller.

These batteries work like they are supposed to, but, unfortunately, when I put them in my Bamboo Ink (which is connected to my PC via Bluetooth) my computer indicated I had 60% battery left... literally seconds after I opened the package and put them in the stylus. I know that batteries drain over time naturally, but 60% was kind of a disappointment.

These batteries are necessary to replace the ones in my Surface Pen. Wish they were easier to find at other locations, but this worked perfectly.

Look at all those A's......they've got 4 of them! Each one making these batteries smaller than their compatriots with fewer.

Don’t need these very often but handy to keep a pair around when I do.

They are batteries, what do you expect. Just wished they were rechargeable.

I am glad that I was able to find these at Best Buy. This battery is hard to get without purchasing online.

This was an expensive and hard to find this battery. ...

Solid battery that is hard to find in most stores. Went to 6 different stores before buying at Best Buy. Well stocked

My surface pro pen battery died needed a replacement. The reason for 3 star is because of Bestbuy customer service. For two weeks I was stopping by to the local store and it said out of stock, customer service was not helping. Bestbuy online said that my local store had it stock, so I was forced to order online and pick up in store. They should really stock these batteries next to surface pens.

These batteries work well. If you need aaaa batteries get these.

They are batteries, and they worked. I am writing this review because I got an email asking me to.

All batteries should last a bit longer it seems. Didn't see a rechargeable option for this size

I bought these as they were cheaper than the rest. Let me see how they perform.

The battery is certainly a energizer if it is used in products that draws small amount of volt.

Thwy were nothing special, they serve its puroose.

AAAA batteries are pretty difficult to find. Bestbuy had them but only in 2 packs or 16 packs.

Got for a pen i was using for my laptop...........

There were not many choices available in the AAAA size, but have had good luck so far with other sizes.

This is the first time I've ever used AAAA batteries, and for a Surface Pen. They are lightweight, small, and have good battery life, but I never thought about them until now. Am still a little concerned about their overall availability but they work well.
