I have always preferred Duracell batteries because I believed that they were less likely to leak.
However the Duracell battery in mouse leaked and damaged the mouse, and the Duracell battery in a clock also leaked damaging the clock.
The mouse was used every day and changed as soon as it quit working.
The battery in the clock was changed as soon as the clock started losing time.

What is your experience with batteries leaking?

In my experience, alkalines will leak after they're run down and past the expiry date (e.g. in the graphing calculator which sits in my desk, getting used once every 4 to 6 months).

After wiping down the mess (the layer usually chips off using a fingernail or knife, and would probably dissolve quite readily in vinegar), the devices should work just fine. CAUTION: the white stuff is probably quite alkaline (basic), make sure you wash your hands thoroughly with soap after finishing. Stop immediately if you feel a burning sensation handling the materials--on second thought, gloves might not be a bad idea.
