Query: cheap but doesn't last long

UPDATED REVIEW (12/15/2012): This battery died after using it for under 1.5 months. I took a risk with the dirt cheap price and thought I would come out fine. The battery was being used in an exercise heart rate monitor where the original battery had lasted a good 6 or 7 months. Rather displeased this battery died so quickly but it does not seem as painful since it only set me back a little over a buck. Still, beware of short lifespan! Downgrading the rating to a single star.ORIGINAL REVIEW: I hate going to RadioShack or a big box store to get a single, small item. This battery is priced well, came quickly, and works fine. Not much else to say about a battery!
