Customer Ratings & Reviews

They fit the surface pen just fine. But as a heads up, you don't need to buy batteries when you purchase the surface pen since it comes with a set of batteries, but it is nice to have a back up set. Not sure yet how long they will last (as compared to other brands) but for the price I was happy with my purchase.

To the pencil of my Surface the battery was finished and I found this package of 4 AAAA batteries in BestBuy for better price than other sites. I already replaced the battery in my Surface Pen and it came back to life.

Size matters not. The force is within these pint sized batteries, that will last you a long time if you don't use the device too often. I used them in an electronic pen. Use it for 4-5 hours a week. Lasts around 2 months.

My Surface Pen stopped working, and I thought I was going to have to replace the pen and it was $100! Bought batteries to try first and they worked! Was really hard to find this size battery, but Best Buy had it in stock.

I need AAAA batteries for the stylus on two of my laptops. They can be hard to find! These AAAA alkaline batteries from Insignia work fine and cost much less than other options I've found. This is the second pack of. These I've bought.

I appreciate that BB had them in stock. They are used in the "stylus" pen used with my laptop. Very few place (like Target, Walmart etc) have them. Best Buy did. They were fresh and reasonably priced. Thanks BB!

I got these to use for my Surface pro pen. They work just like the should. Have been using them for 5 months now and no problems, and I think they have a better charge on my pen then the last ones I had at the 5 month mark.

They're AAAA batteries, there's not much to say. They work well. They've been lasting me a while. I bought these for my Microsoft Arc mouse and it's been 6 months and the mouse is still working on the same two batteries. Good value for the price.

I wish AAAA were easier to find. I have had my Bamboo computer pen for a few years and seems to be getting harder and harder to find AAAA batteries. I only need to find them every couple of years with how long the set lasts in my pen.

These batteries are small but have great battery life. I haven’t even changed my first one and it’s been over 6 months. However, I don’t use my surface pen everyday. I can imagine you’d get less life if you consistently used it, but still a great purchase!

I was looking for AAAA batteries for my stylus at deferent stores and was able to find at BestBuy store. It was the last pack at that store. I don't know yet if Insignia battery runs long as I just bought it recently but the price was pretty affordable.

Needed a AAAA size (smaller than AAA) battery for my new surface Pen. 4 pack is ideal, and a good value. So far so good on power and life. Glad best buy had these in stock.

Great deal and great quality. These batteries last long when used with my toys. If your toys require long lasting batteries, get these. Great for my flashlight, clock, and other adult toys.

These batteries are some what specialized, I only know of one device that uses them. That is the MS Surface Stylus. Without them your stylus will not function, always carry a spare if you use the stylus a lot.

I use these batteries for specific bluetooth pens for computer/tablet screens. Compared to Energizer and Duracell, these don't last as long, but these batteries aren't as easy to find, they are also priced at a much lower cost, if used conservatively these should last you much longer without breaking the bank.

Didn’t know they made AAAA batteries I purchased them when I purchased the pen that requires them and long lasting batteries

Went to buy a 2 pack and BB only had the 78 year pack-o-12. In any case, I used the one I needed and here it is 2 years later and its still working! Not bad Insignia....not bad.

This size battery isn't always available, but Best Buy had plenty in stock in a variety of package sizes. When the batteries were installed in a lighting device, they were strong and worked well. I can't comment on how long they last.

I didn't know my computer stylus required batteries until it stopped working. I didn't know that AAAA batteries existed. I purchased these batteries and they got my stylus up and running perfectly.

I’ve been working with my previous battery in my surface pen for over 2 years with this brand and am just having to replace the battery for the first time. Reliable.
