i have a HP wireless keyboard and mouse... got it with my HP Pavilion desktop.
batteries are not rechargeable..
mouse>> 3 weeks with normal usage (4 weeks for duracell)
keyboard>> 2.5yrs+ yeah thats right.. the duracell bats havnt discharged since i purchased my desktop in 2005. dont know why and how.. even though i use the keyboard more than the mouse.
the keyboard batts should last longer but mouse wont last for more than 3-4weeks..if their rechargeable then it doesnt matter anyways.

Buy a Wireless keyboard but don't buy wireless mouse as the battery will end very fast in the case of mouse. My friend had bought also an iBall keyboard and mouse one year ago. Since then he has changed his keyboard batteries twice and the mouse's batteries more than 20 times.
The Wireless Optical Mouse is slick and stylish. It sports a comfortable ergonomic design, with added points for being ambidextrous. Perhaps because of the latter, Microsoft sticks to a simple three-button layout, which you can configure however you desire.The good: Long battery life; easy to install; stylish design; innovative scrollwheel; ambidextrous.The bad: Wordy instructions; no user manual.
