Question 1

What type of batteries does it use and how long is the battery life?

Accepted Answer

2- AAA, I have 2 of these, I put Duracell's in day 1. 1 of them is 2 years old and the battery's are still good. It seems to go to sleep when not in use, Just press a button or wiggle the mouse and it wakes up.

Question 2

is this keyboard compatibility ok with windows 8?

Accepted Answer

Yes, it works great with my new Windows 8.1 machine. I've bought three different wireless keyboards with trackball and this is the best of them all, plus a great deal for the price. It's small size makes it portable and the scroll wheel is very convenient.
