They work but the charge does not last as long as the Sony branded battery. Good for a back up but not as a primary battery.
UPDATE 3/4/2018: The seller offered to exchange these. I'll update again after trying out the new batteries.
3/9/18: Replacements arrived today. I'll charge them up and test them tomorrow. I'll update after trying them out.
2nd UPDATE 3/12/18: The seller is great about their customer sercvice. They sent two new batteries at no charge to me. The battery still isn't that good. After taking just 50 photos, they were down to 10% power left. My original review stands. Great for a back up battery.
