text: Update on battery
  
  Although it appears to be a genuine Sony battery, it held less charge when I got it in 2017 than the battery that came with the camera that was a couple of years older. Now, after 1 year it will no longer take a charge. Probably a quality control issue as others have said. I've just purchased another from Amazon, as Sony lists Amazon as an official retailer. I'm hoping it will do better. 2019 update. I'll stick with my 2 star rating. The battery I got appears to be a genuine Sony and has the hologram. However, it doesn't hold a charge as well as the one that came with the camera back in 2014. The 2014 battery weighs 2 oz and the 2017 battery weighs 1.5 oz, which goes a long way to explaining the poorer performance.
