The Surface Pen (opens in new tab) is an incredibly useful tool and accessory for the Surface Pro, Surface Studio, Surface Laptop, and Surface Book. It's a battery-powered peripheral, meaning at some point the Surface Pen will stop working unless the battery is replaced. Don't worry because changing it is easy. Here's our step-by-step guide to help you along.

Note: Make sure you have the correct batteries before you begin. A single AAAA battery is required for replacement, meaning you may have to find replacement batteries online rather than in stores.

How to insert a new battery in your Surface Pen

  1. Place the negative end of the AAAA battery into the body of the Pen (the negative end will be marked with a minus sign [ - ]).

  1. Slot the top of the pen back into the body of the Pen. If your older Pen has paper attached, make sure you fold that back in with it or remove it. The new Surface Pen shouldn't have any paper.

  1. With some force, push the top of the battery into the Pen. If you're using an older Surface Pen, you have to twist the top to secure it.

How often should you replace the battery?

Microsoft says the Surface Pen lasts a year on a single battery. That estimate will vary depending on your use of the Surface Pen, however, so it's always handy to have a spare battery ready.
