I have had numerous high value items damaged or destroyed by leaking Duracell batteries Destroyed - geiger counter - emergency short wave radio - high powered lasers (3) - High powered flashlights (2) Damaged - 8 inch Schmidt-Cassegrain telescope tracking motor - vintage geiger counter For years, Duracell was my go to brand but I will never allow another in go into ANY of my devices. I've incurred hundreds of dollars in device repair and replacement.
