Yes, unfortunately, the new battery is big like the old batteries of many years ago, the recent batteries of a couple of models ago don't fit :-( I like this camera, but I don't LOVE it like I did my previous 5 x Cybershots.
Absolutely agree with Draconic. When I first bought this camera, I was taking so many HD videos and photos, that I burned though the first battery in a day. Fortunately, I had purchased a second battery, and had it all charged up and ready to switch out the minute the battery indicator warning light started flashing (It'll start flashing when it drops to approximately 5%, and then flash faster and faster until the battery is dead). Good little camera, by the way. It also includes a battery charger.
