Customer Ratings & Reviews

So far these have worked out well in all my smoke detectors. None of them have leaked in the devices or in storage. They seem to last more than 6 months at which point I change them out for safety reasons in the detectors. Great pricing when on sale.

I always stock up on batteries when they are on sale! No one should have to make a special run to the store when the lights go out because a storm is coming through town, or your kids get a new gift that needs batteries. They last for YEARS!

I’ve always had good luck with the Insignia brand products so I wasn’t hesitant to buy these over name brand batteries. I honestly cannot tell a difference so I would buy these again over the big name batteries.

The insignia batteries work very well. They are priced much lower than the big name brand batteries. They last a long time, but not as long as the big name brand batteries. I will keep buying Insignia batteries.

I thankfully have not had to use these, yet. I got them on super sale. I know they have a great expiration date. Living in Florida, I hope I don't have to use them during hurricane season, but I do get a warm glow, knowing they are there.

At less than $1 a piece (they were on sale), these batteries have performed as well as their name-brand competitors. I have purchased other Insignia batteries in the past, but these are my first 9Vs. Very pleased and will be purchasing them again.

Got these on a Best Buy Daily Deal at a very low price for this quantity of 9 volt batteries. Plan to use them for the smoke detectors in my home. Have not installed any yet so I can't comment on their longevity; but, they look well made and I don't anticipate any problems. At the Daily Deal price, they were at least half the cost of other sources for 9 volt Alkaline batteries.

Needed some 9 volts for the smoke detectors. These popped up as a bonus Deal of the Day at a very reasonable price. They perform as well as any of the major brands.

I have multiple smoke detectors in my house, The batteries all needed to be replaced. I found these which were reasonably priced. I switched out all my batteries and they seem to be working fine.

I have purchased a ton of batteries (for our church sound team) to use over the years. We have not seen any significant difference between this brand and it’s big-name-rivals. I would highly recommend saving money and going with these!

Recently needed to have these for an older smoke detector. It was great that Best Buy has their own brand. They seem reliable and I would purchase them again.

These batteries work just fine in our smoke alarm so why pay a higher price for a name brand battery. I’m happy to find them and I’ve already bought more batteries in this same brand, just a different size.

I'm officially an Insignia brand customer now for just about everything they offer. Never had problems with best buy brand items so i would definitely recommend to other people. price and quality is still perfect.

Great value when they are on sale. I use them to replace the batteries in the smoke detectors every year and they are just as good as the name brands.

I got these batteries for carbon monoxide/smoke detector combos in my house. Now admittedly they drain batteries pretty fast but this batteries life was comparable to Duracell.

These batteries are as good as name brand in my opinion. I use these in smoke alarm units in several locations around the house with no problems.

Very solid. Looks nice in blue and white (not that it matters). So far so good. Lots of applications but purchased it for ALL 8 smoke detectors in my home. Builders went a little crazy putting smoke detectors every there.

Bought these for replacements in our smoke detectors. Used several for a science experiment to make a Styrofoam cutter (added copper wire) and it heated up faster than any other batteries we tried. Best price I could find on 9V batteries.

At $8.99 for a pack of twelve (12), what's not to like? I can tell no difference in the performance of these 9 volt batteries and duracell, etc. All my smoke detectors and CO detectors use 9 volt.....so I'm all set. Great value!

We needed batteries, and we stopped by Bes Buy to get them. They work like they're supposed to, except Best Buy charges a little more than what you can get them for at a gas station. With all the technology in 2021, you'd think that someone would invent an electrical device that last longer than a battery. If Edison had let Tesla perfect his over the air electricity, the world, by now, would be a vastly different place. Instead of making Tesla his rival, they could have invented an electrical storage device that would cement their legacies for a millennium. Anyhow, it's a battery. It works
