    Pesky fire alarm gives dying beeps in the middle of the night and this product gives longer life to the fire alarms.

    Got this pair at a good price. The alarms in my home use this size, so it was a good chance to change batteries. My previous batteries were also Energizer. Cannot go wrong with this brand.

    The product arrived on time. There were no problems with the delivery, and no damage to the package. I will not be using the batteries soon, but do expect them to be completely functional.

    Can't beat the dependability and longevity of Energizer brand batteries. It has been the only brand of batteries I have bought for years! The competitor brands clearly don't last as long but interestingly enough are priced similarly. Stick with Energizer and you won't be sorry!

    I've been buying Energizer batteries ( regular and rechargeable) for years. These batteries seem to always last quite a while for my battery operated smoke detectors and fire alarms. I highly recommend this brand.

    These batteries are truly amazing! No, that isn't saying enough! These batteries are positively electric! It doesn't matter how much a store might charge: buy these batteries! Have you ever awakened in the morning and said "I think I did well"? That is the sort of satisfaction you will get from these batteries.

    Not much to say about batteries. They work. About 1 year of the shelf life was gone but these last a while. Had some rewards to burn and bought these at Best Buy.

    No, not the Metallica song, from the 1986 classic 'Master of Puppets' album, but like a battery that goes in your smoke alarm. That is where I put my battery. Battery is a kick-butt song though. These Energizer batteries are pretty good too! Battery is found in me, Battery! Battery!!
