I got these 2400's and 1 hour charger for mine:
http://www.maplin.co.uk/Module.aspx?ModuleNo=45804&criteria=batteries&doy=17m11Went to aintree to get them, absolutely made up with both the quality of the batteries and the charger. There has since been a few "better" Maplin chargers available with the same batteries for cheaper then this.
It includes a 12v car charger adaptor as well as the normal mains adapter too, which is very handy for when you forget to charge the batteries.
My batteries tend to outlast my memory card (2GB), the other week at Hilbre for instance, I shot over 300 photographs and around 15 minutes of video, and the memory card/backup memory card/phone memory completely ran out, but the batteries were still fine.
With flash, they give about 420 shots, in night mode with 4 second exposures, they give around 360ish.
Only take an hour to charge. Lidl were doing 4x 2500's a few weeks back for £1.99 and stupid me forgot to pick some AA's up (only got AAA's for me DECT phone), so its really the chargers that cost the money nowadays.
The charger is a 1 hour charger, you can get faster ones, although there is some debate as to whether the 15 minutes chargers and the like actually shorten the life of the batteries, both for use and overall.
But 1 hour is pretty good imho, and given the capacity of the batteries, its pretty fine. If you dont use your camera much, you may prefer to go for something like 1300's however, because they will hold their charge longer without use then 2000+ batteries.
