Query: leaks acid and ruins electronics

I almost always bought Duracell Copper Top batteries till this year. I've had four clocks ruined and my expensive laser level ruined by Duracell AA and AAA batteries. All had expiration dates of either 2013 or 2014. I've swapped out all Duracell batteries due to the amount of damage I've experienced just this year.
