Customer Ratings & Reviews

Bought these for my smoke detectors. Change batteries once a year if they need it or not to keep your family safe.

Since these batteries are extremely expensive for a 2 pack, this pack was extremely what I needed to change out the batteries for my chirping smoke detectors.

Woke up to a beeping smoke detector last week. Ordered a pack of these and they did the trick. Don't know how long they will last, but for the price, you can't beat it.

I got these 9V batteries for two applications: 1. My smoke detectors 2. My acoustic guitar pre-amp Thry fit fine in the smoke detectors, but were too fat to fit in my guitar. Hold them up next to some of the "copper top" 9V (which guitar maker recommends) and you can see they are much thicker. So they're not a drop-in replacement for every application. Too bad. My guitar drains batteries much more quickly, so I'm a bit disappointed. Had good experience with the AA size batteries though.

These are good quality, economical batteries -- no problems or concerns so far. They are less costly than name-brand batteries.

I haven't purchase 9V batteries in quite some time. I needed to replace the old ones in my smoke detectors.

Will, the Fenton, mo Sampson rep was terrific!!!!! He helpe set upy Gear s3 watch! Best Buy is lucky to have such a professional representime in their store.

These batteries seem just as good as other name brand batteries. Have used the 9 Volt, The AAA and AA and C batteries and see no difference except the lower price.

Was skeptical but became a believer. I usually only purchase the major brands but these last well and shelf life is good as well

Anytime bestbuy has batteries Onsale I try to snatch them up. They last the same amount of time as the competition for a fraction of the price.

If your board take the brand sticker off these batteries and a specific “name brand” battery, you’ll see they are manufactured in the same facility.

Affordable batteries, used them to replace old batteries on smoke detector.

These 9v Insignia batteries are excellent for the price, but don't forget they most likely won't hold their charge/power for as long as Energizer's 5 year ones supposedly do. Finally, buy them on clearance sale or as "deal of the day" if you can.

I have not used these batteries yet, but they were needed, and a very good buy. Came quickly as promised, and packaged well.

I have installed the batteries in all of my smoke detectors and am looking forward to not hearing any more alarm beeps for quite a while.

How do you review batteries? They were the correct size as stated....they work in my device.....and easy to install. LOL

These are high quality batteries, with good time remaining before expiration date. I have used them here and there at home and have no problem so far.

These batteries are just as good as the expensive ones, but a better value. Plus this package makes it easy for the yearly change of batteries in the smoke detectors.

Great Price batteries and the last just as long as the other more expensive ones.

Loved these batteries. So excited to see my decorations all lit up thanks to them.
