I have used both the Sanyo 2500 and the Fuji 2500 rechargables.
The Sanyo was crap (as all of you may already have known from another thread) and now, after about 20 charges, my Fuji batteries are also not holding charges for more than 2 days! This is very upsetting as the batteries dont come cheap. I'm going to buy new batteries (AA sized). What do you guys recommend? Which are the most durable ones? Should I change my charger too (currently using a Sanyo Quick charger)
