Dear Oleg, thank you very much for your recognition of our battery quality, logistics, and service. We have Genuine Original Molicel p42a battery. The voltage, capacity, internal resistance, maximum discharge current, and maximum heating temperature of the battery all meet the standards. For the issue of QR codes not being able to be scanned, we have also selected a portion of our upcoming shipment for scanning and consulted with Molicel's agent. He told us that the QR code needs to be scanned using specialized equipment within Magic Company. Thank you again for your recognition and support.

Dear Clemente,Thank you for your feedback. Please continue to support our company，we will do better and better
