I am very disappointed in this battery. The life time of the battery is very low...maybe 60 minutes. When snorkeling in Hawaii, the battery life was shorter than my duration in the water which was less than an hour. I did take a few pics on the beach as well, but I ran out of battery juice in about an hour. I am looking for a battery for my W30 that will give me more life time on the battery. You don't get many pics on the life of one fully charged battery.
