What are the best batteries to use for a wireless keyboard and mouse? - rechargeable keyboard and mouse

I have a wireless keyboard and mouse that came with my Gateway PC and with batteries pretty quickly. I use my computer all day, and I know that the battery last longer and I wonder if I could use rechargeable batteries, to save money on batteries.
