  • Did not work
    Verified Purchase

    This would not work in my Sony Camera. It looked just like the original Battery in size and shape but the camera would not recognize it. I have since read that Sony puts a chip in their batteries and if the camera doesn't recognize the chip it will not allow the battery to work. Sony is getting to be a piece of crap and I'll never buy another Sony Product that requires me to purchase only Sony Overpriced Products to allow it to operate.

  • Did the job, for a lot less money!
    Verified Purchase

    I bought my Sony camera from a local ****. Looking over the specs, I noticed their specs said battery life was approximately 230 shots..... not good, if you're out all day taking photos. Their website listed off-brand replacements at almost $30 EACH. I bought two replacements here on O.CO for right around $* each. Tons of money saved, and the product does exactly what it is supposed to do.

  • Backup Batteries
    Verified Purchase

    Purchased these batteries as a gift for my Mom who needed backup batteries for her Cybershot camera. She says they worked the same as the battery that came with the camera and fits the charger also.
