What is the battery life expectancy of this keyboard?

I have been able to get a couple months out of the batteries that came with it. I suspect Lithium batteries should go easily twice that (all depends on the use level though...).

Where is the Fn numpad? The keyboard I received has a different layout, and does not have the numpad and no num lock

There is no numpad, either physical or virtual. This keyboard relies on actual typing skill to reach the numbers above the letters.

Every time I type on the right-side, I get numbers instead of letters, how do I fix this?

Click FN and lock number keys at the same time.
