gets the job done
I needed this for my garage opener (looks like a half-length AAA). Package comes with 5 batteries at the same price as they sell at the stores for just a single one, so the purchase is a no-brainer. Not sure how the "5-year warranty" works, but this is an out-of-sight-out-of-mind kind of purchase, and it's working so far.
