Query: lasts all day

I take about 700 - 1000 photos a day (640x480)res. with a olympus sp-550uz.These sony batteries charge quicky (I bought the sony quick charger) and they will last you an entire day or more.Buy these batteries if you take a lot of photos, they are worth it.I bought these to replace a set of cheap "power 2000" rechargable batteries. (amazon sells these also, I got the "power 2000" batteries free and they were not even worth charging or using. They consitently died after about 150 photos.)
