    These Energizer Max batteries seem to last longer than the mediocre batteries I had in the smoke alarm. Got tired of changing the battery after the annoying chirping always seems to start in the middle of the night!

    so as with my other reviews - check for rebate program & for ones on sale - you can stack - great way to save on batteries - we all have remotes etc that need batteries and rechargeables dont always work for all of them
