never thought it would be that short of a time span.

my alkaline 9v (Duracell) in my other smoke detector has been there for 3yrs so far.

That's why you don't buy batteries at the dollar store. Same thing happened to me. They are sh|t batteries.

That's why you always use alkaline batteries. Just get them at walgreens for cheap.

Yep, the recommendations are to change the batteries when the Daylight Savings Time changes...although with the new DST law, that means the batteries will be in for about 8 months during the warm months, then 4 months during the cold months...

Why exactly are heavy duty batteries called "heavy duty" if they're the cheapest, lousiest things on the market? Don't they use the ancient zinc-chloride recipe?
