There are no batteries available for the SZ1 or SZ3. I have been trying to purchase a second battery for my new SZ3 since August. Panasonic told me in August that they would be back in stock in Sept and in Sept they said Oct and today they said on Dec 15. One store I talked to said that the firmware upgrade that was to keep 3rd party batteries from working is messing with the Panasonic battery also. Wouldn't that be justice. 
The SZ3 is a fabulous camera but I can't recommend it to anyone until Panasonic solves there battery shortage.
