I'm surprised that you would not see the problem here. If you bought milk
with an expiration date of Tuesday, would you complain that the milk went
sour on the Friday after? Batteries contain corrosive chemicals and are
guarantied to leak if you let them sit long enough. Two years past
expiration date doesn't sound like a lot, but you can't say it is the
battery's fault.
 
BTW, if you check around you will find dated alkaline batteries are
typically dated for a 10 year shelf life. So you likely bought that pack in
2004 or 2005. The article you cite talks about 2024 dated batteries and the
article date is 2014.

I see a lot of applesauce. "Duracell "AA" and "AAA" alkaline batteries
consistently leak at a 20 - 30% failure rate from packages no older than 4
months." So if I buy a pack of 48 cells, I should see leakage in 10 of them
in 4 months? I've never seen a Kirkland cell leak and I've bought some half
dozen packs, not counting the 9 volt batteries.

I think the only way to tell is to try. Did you contact Duracell about any
leaking cells?

The issue is not leakage, but premature leakage. I've had two devices
impacted by leaking alkaline batteries. One was clearly not left in a
device past it's date because it was a clock that ran until the battery
failed and the cell was dated so Duracell paid for it. I don't recall the
other so much. It was a much less expensive item and the battery was a
Rayovac. Their warranty required the return of the clock to them for
examination and possible repair.

A genuine maker and seller of 0.1R, 2W w/w resitors would wind them with
nichrome wire that could carry 4.5 amp current continuously but a
genuine 5W version , he would use wire that would have to carry 7.1 amp
continuously
