    Theses were on sale just in time for the time change. Change the batteries in smoke alarms. I trust these batteries. Never had a problem with them.

    Great battery. Great price. I've been using Insignia batteries for over a year in motion lights, remotes, and smoke detectors. Have not had to replace them yet. When Best Buy puts them on sale, it's a "no brainer" to buy them.

    Always good to have extra batteries on hand. Insignia brand was a good value for the price I paid. Had a small dollar amt coupon from BB and this was a useful item to use the coupon on.

    I did not know what to expect because I always buy the same brand batteries. These went on sale so I gave them a try. I think they are really good. They seem to be outlasting the name brand batteries I have been using for years.

    We need them for smoke detectors, so they’re only in for six months at a time. These batteries do the job and are cheap and reliable.

    This is such a great battery to change our your smoke alarms every year. The price was amazing, and they last as well as the more expensive ones. Since I change them once a year if they need it or not, why spend 3x the money?

    I grew tired of buying 9v batteries in small quantities knowing I'll be doing the same thing in a few months. Picked these suckers up when they were on sale. Now I'm all set to replace all my smoke detector batteries at once.

    I'm always surprised when I buy Insignia batteries. They typically outperform expectations, especially considering they are a "house" brand.

    Don't opt for the more expensive name brand batteries, Insignia will do just fine. I used these to replace some beeping (ANNOYING) smoke detectors and they worked as expected.

    My smoke detectors were beeping and needed a new battery. 9V batteries are so expensive. Picked up this set from Best Buy when they were on sale and they work great. No more beeping smoke detectors.

    This multipack of rayovac 9v batteries was a offered at a great price.. Each battery was less than .50. Normally 9v batteries can cost $1.00 each and up. This was a steal for all those smoke detectors.

    My smoke detectors kept beeping, so it was time to replace the batteries. The batteries I got did not last very long. After reading reviews, I decided to give BestBuy brand a try. They were on sale, so the price was good and so far the smoke detectors are quiet.

    How exciting is a review about batteries? Well, I needed a bunch for my smoke detectors and these were cheap enough, that if I have to replace them in a year, I wouldn't be upset. Anything else?
