Speedlite 580ex Ii Batteries

Best rechargeable batteries for Canon 580EX II Flash?

I just ordered a Canon Speedlite 580EX II Flash for my 40D and want to watch rechargeable batteries. There are many out there and have no idea what are the best (who claim to be), that is to last longer, the cooldown shorter, to hold office, etc. Some idea? Thank you.
