Reliability of batteries and their damage to equipment

[Eric H]

Interesting coincidence that I removed two sets of leaking Duracell Alkalines today, one from a CD player the other from a remote control.

One pair had an expiration date of 2015, Neither device was seriously damaged.

I just checked all my remotes, all Duracell's with 2009, 2014 and 2016 exp dates and they are all fine.
I think the problem occurs when the batteries are dead and remain in the device, dead ones corrode.

I bought a huge pack of AA Enercell Alkalines from Radio Shack a few months ago when they had them on sale for $10, hope they hold up.
