Rating : - Wow, CHEAP batteries but work just fine
So I was checking out in line at a major discount retailer thinking about needing some batteries for my smoke detectors at home. I saw that they were around $2 a piece! Since when did batteries get so expensive?

Now I know, personal safety is more important than the $10 worth of batteries needed to put fresh 9-Volts in all my smoke/fire detectors, but still...

So I skipped that purchase, came home, and started comparing prices on some batteries. These came up pretty quickly in the product search on Amazon so I decided to try them out.

They work great! They've lasted at least 8 months so far (aren't you supposed to change them every 6 months anyway?).
