Batteries (photography)

Shopping for a replacement battery for my Canon S70 I tried to find out where to buy good batteries, this is what I found from information on google:

Sterlingtek

Many recommend Sterlingtek, but some complain that the physical size of some batteries are wrong. Their capacity ratings also seems wrong.

PowerSmart

I found some who recommended PowerSmart? as a better alternative to Sterlingtek. They are made in Japan.

Duracell

I actually ended with a battery from Duracell bought from http://batteribyen.dk, look under Duracell (they are not listed under camera batteries).

There is also a Duracell shop: http://duracelldirect.dk
