Allmax AAAA (4A) Maximum Power Alkaline Batteries (8 Count) – Ultra Long-Lasting, 5-Year Shelf Life, Leakproof Design – Perfect for Surface & Stylus Pens, 1.5V

I ordered these batteries as replacements for my surface pro stylus and they work like a charm. They have a long battery life (I use my stylus often as I am a student) and go many months without thinking about having to replace them. They also hold charge for a very long time, given that you won't need to replace your battery for long periods of time. I would definitely recommend to anyone who's interested!

I have been using Radio Shack AAAA batteries to power my Streamlight Stylus light. The last batch of 8 batteries 2 were leaking and 3 were nearly dead. These batteries are full power and work great. AAAA batterys are hard to find so thank you Amazon.

These batteries are well made, have long shelf life and sealed construction to prevent leaking common to most batteries. Used in devices that operate infrequently, so it is important that they do not leak and corrode electronic devices.

Small battery

Arrived quickly after ordering! I use these batteries in my surface pro pen and I have absolutely no issues with it. My pen is always being used and has been on constantly since I got it. The other review should be deleted. Giving a review for their own mistake isn't very appropriate or fair.

These batteries are a great value for your money

Use these in my active pens for my surface laptop and my Lg Phone. Have only hade them in the pens for a few months but they are working fine and much cheaper than any other 4A batteries.

Okay, I'm 72 and we all know that elderly people get confused. I won't lie and say that I don't. I do. I know it. But, when I read about these batteries, I set my eyes on the words "TV remotes". I thought they would replace the batteries in my TV remotes and I have three of them. They all take four AAA batteries. My eyes didn't notice the extra A on these Allmax AAAA Maximum Power Alkaline Batteries. I just saw the Ultra Long Lasting and thought how wonderful they would be in my remotes. Unfortunately, they won't fit. They are tinier than the AAA batteries in my remotes. My error may help some of you avoid the same mistake. These are AAAA batteries and they will not replace AAA batteries. Just make sure that you check the electronics you have and see if they will actually work. I'm sure these are good batteries, they just don't fit in anything I have. I'll save them and maybe I will have something to place them in. I do recommend them IF you have something that will use them!
