Review on Duracell Ultra Photo AAAA Alkaline Batteries - Long Lasting, 1.5 Volt Specialty Battery for Household and Business - Pack of 2 by Allison Sanchez

I have a Microsoft Surface Pro 4 as a laptop. This is where the screen attaches to the keyboard, which also doubles as a cover, and you can use it like a regular laptop or tablet. It comes with an on-screen stylus and makes it much easier to touch small areas of the screen. One of these batteries lasted 4 years in the pen. The pen is technically always on so it's always drawing power and I use it quite a bit too so those Duracell batteries are awesome. For comparison, I had a regular pen battery and it died after about 6 months. This is a key difference. From now on I'll stick to her. I also recommend Duracell batteries. I have about 40 of these, I've had them for about 5 years and they still hold a good charge and last a long time. The best part is that they can be charged in just 30 minutes.
