Duracell AA Alkaline Batteries, 48 Ct

I just opened my wireless Apple Mouse to change the batteries and discovered that the batteries had leaked significantly. I've never seen a battery leak this much and the batteries are still within the best before date. I also recently changed the Duracell batteries in my Keyless door lock and they had also leaked slightly. While I haven't used the Apple mouse for several months this shouldn't happen. I haven't tried the mouse yet so hopefully it hasn't been damaged by the excessive battery acid.

Using Duracell for over 30 years. Was in public safety so lives depended on batteries. During the past few years our devices have been damaged by leaking batteries and actually were still holding power. Flashlight batteries leak during short term storage, and electronics would still work, but the batteries leak. Something changes as this was never an issue years ago. Now it's almost a guarantee the batteries will leak. AAA are the worst with C right behind. 9 bolt seem to be the only ones that don't leak.
