Hard to find these size Just what i needed for my surface pen

I was looking for these batteries for a wacom stylus and it takes AAAA batteries. these are hard to find and usually have to be ordered online. I was very glad Best Buy carries these. They work perfect and it's a 2 pack so i have an extra.

They work great long lasting, but to have to pay over 7 dollars for two batteries is not okay.

I did not even know AAAA batteries existed until I bought my new incredible laptop at Best Buy. No place else had these but Best Buy and they are good batteries at a fair price for such a unique product.

Batteries, you get the idea ;) These are exactly what the package says, batteries.

Very helpful product need for my laptop hard to find these types of batteries

Good batteries and they last long, don't see myself needing more anytime soon

These batteries, lemme tell ya, they really work. I took my old cell out and put a new one of these in and guess what? They managed to turn the dang thing on! Holy cow!

Quick shipment of a not very common battery size. Works great with surface pen

They powered my stylus just fine! I have no complaints!

They lastin me a good ol long time. Bought em for a pen and Id buy them again.

Great batteries and they are harder to find! Thank goodness Best Buy had everything I needed INCLUDING these batteries! Great price for a great battery!

Only type of double a batteries I could find. I used these batteries in my Microsoft surface pro 3 stylus. These batteries seem to last a few months, depending on how long/ how much you used the surface pro 3 stylus.

The battery is pretty good. I bought it for my pen.

The most phenomenal batteries in the entire universe! Come on, they're batteries. I needed this type for my Surface Pen. Best Buy had them, so I bought a two pack.

I had no idea AAAA batteries existed until I had to replace the one in my Surface Pen! I thought, Nobody is going to have these batteries except maybe Best Buy... And they did! Love Best Buy (and the batteries too)!

Only place I town I could find 4A batteries for surface pen. 1 year strong and haven’t had to change them out yet.

Rare battery - Hard to find stylus battery at a decent price.

Batteries are quite long lasting, as I use them for my surface pro pen, and it keeps it running for more then a year. Though results may vary for other products that may use more power.

They work just fine, like any other battery, but they're really pricey for just two batteries. You could probably find a better deal elsewhere.
