I had no problems with my third-party batteries but when Sony added that annoying warning message about them I decided to get another first-party battery just to avoid the obnoxious click-through. Purchased June 2019; it's now October 2019 and the battery just suddenly died partway through the day. Won't power the camera, won't charge. It's an $80 brick. My two third-party batteries (purchased May 2018) are still going strong. Not wasting my money again.
