I've noticed on vacation is that a second battery is necessary when on a trip at a time has a lot of beautiful motives in front of him that you want to keep as a reminder. So far I have always been reluctant because an original battery was only to obtain a rather high price. But for such a low offer was clear to buy the product as a replacement battery for my digital camera and I have not looked back. After charging to the original charger inserted in the camera, it was ready for use.
