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.

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.

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.

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.

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!

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.

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.

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.

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.

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.

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.

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.

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!

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.

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.

Reasonable price, last for quite a while, would buy again
