Query: Long-lasting battery

I purchased this battery for my husband's Samsung camera which took the CP1 Duracell Battery which I could only find online and it was very expensive. I decided instead to purchase three rechargeable batteries and the charger so he would always have an extra, charged battery. He used it for the first time at a weekend event and it worked great! He didn't have to change the first battery until after the first day!! Very satisfied with this item and received it quickly.
