Review on 🔋 Duracell D303/357 Silver Oxide 1 Count, Pack of 6 - Long-lasting Power for Your Devices! by Stephanie Thompson

Batteries have not been used two months after purchase. Opened to replace dead batteries in a laser sight. It's like a loudspeaker's laser dot, but mounted precisely on a gun. I used two at a time. Got five out of six and they all went down within seconds of turning on the little laser sight. I checked the voltage on all six new ones from Revain and two old ones that were taken out of sight. The old ones reported even more voltage than the one that wasn't installed! The copyright on the box says 2019. It should be good, but it isn't. I bought Swiss because I thought they were better. They weren't.
