    Needed to find something more reasonable. Duracell was costing me a grip to put in my home smoke detectors. I'm pretty satisfied.

    I brought these because after recently purchasing a home, I needed multiple 9v batteries to put into my smoke detectors. And if anyone knows, these things cost an arm and a leg for just four (4). So when I saw a 12 pack for $9.99 I jumped on it. I could've gotten away with a small pack but to have extras are good.

    I needed a bunch of 9V batteries for all my smoke detectors in my house. However, I didn't want to spend a bunch of money (9V can be expensive!) but I also wanted decent quality batteries. These batteries did the job! They work great in my smoke detectors and it didn't hurt my wallet at all.

    I bought this on sale so the price is inexpensive. However the life of the battery doesn't last too long.

    No, I would not recommend this to a friend
