Customer Ratings & Reviews

Used these for a bass I have, it's been a few months and I haven't had any issues, still on one battery. holds the charge very well.

These batteries were on sale, and were a super buy for generally expensive batteries used in all our smoke detectors. Thanks Best Buy for helping us stay safe at a great price!

Super deal on 4-pack. Always a good idea to have on hand when your smoke detectors are due for a new battery. Don't get caught without a backup supply!

After having had several bad experiences with leaky Duracells, I now avoid them like the plague. Came to the conclusion that these have to be better, even if it's just the price ;-)

You never have too many batteries - I purchase all my batteries at Best Buy when they are on sale to stock up. These are good, last as long as other brands and are a great price.

Insignia batteries seem to last longer than many I have in my drawer.

These batteries work just as well as the name brands at a huge discount off the price. I highly recommend Insignia batteries.

Found these 9Vs at a good price, 4 to a pack, and they are perfect for the smoke detectors at our house. You wouldn't get a better price at a discount store.

These batteries are terrific. They have had 0 issues and are great for fire alarms and carbon monoxide detectors.

An excellent product at a great price. I certainly would purchase this again.

I happened to be in the store looking for a specific battery to put in equipment that take an odd size and found these at a reasonable price! They work perfectly!

9volt batteries are always useful around the house I use mine for my smoke detectors change once a year or when you hear that warning beep!

This is an amazing deal...the package is nice and the batteries are all in line. For what you pay in a store for a 2 pack, you can get twice that amount with this and pay less!

Great value and work just as well as the big name brand batteries as far as I can tell!

this is now my go to brand , great sale prices and as good as any expensive name brand battery

My wife had mentioned that she would like to have a metal detector. I got it for her for Christmas but no batteries were included. I went to BestBuy, walked down an aisle, and noticed batteries. I bought the 4 pack, which was priced competitively.

Bought the pack on sale, MUCH less than the same quantity of anywhere else. Already have one installed in a smoke detector, and should be good for such minimal drain use.

These batteries seem to work just as well as the major brands. No complaints with this product.

These batteries work as well as other brands and are cheaper. Why not buy these instead. I will continue to use these.

Best Buy battery for replacing power source in my smoke detectors
