Perfect for the Surface Pro 3 (and Pro 4) Pen!
on March 25, 2016
I purchased these for use in my Surface Pro 3 pen. Note that this will also work in the Surface Pro 4 pen. Given that the battery life is about a year, this is more than I will ever need!
That being said, the batteries seem to be performing well. I don't really know what else to say about batteries...
