I purchased these 2 batteries and dual slot charger brand new from Amazon in Jan 2025 for use with a Sony RX1R mark II. I returned the camera after a week as it was faulty and so these have been sitting on my shelf for the best part of a year unused. They maybe have had one charging cycle each, come with the plastic case and the charger. I had added pictures of the invoice- total cost of these 3 items was £85.
