Customer Ratings & Reviews

I compared these to Costco's Kirkland brand and these last longer and are generally just a better battery. These are primarily used in my smoke detectors and a few of my children's toys. Buy with confidence.

What can I say? I have been buying insignia batteries for years and they a;ways hold up well. These were for our fire extinguishers

Always handy to have on hand for the smoke detectors. They last a long time, have never noticed a different between these and name brand batteries in a smoke alarm.

Insignia continues to not disappoint! purchased for the office have lasted a month-ish...which is as long as the Energizers I bought lasted!

Smoke alarm started beeping and it was time to change the battery. What a deal at Best Buy ordered online, quick and easy and well the battery worked and the smoke alarm is no longer beeping.

We all need 9 volt batteries for smoke detectors and other items. This was a great deal of the day. Shipping was awesome. Received the very next day!

This pack of 9V batteries comes in handy with all my jobs that require batteries it is nice to have this around not having to go back and buy new ones. These batteries hold their power well.

Ordered this battery to replace smoke detectors and temperature sensors. So far, work good. Will keep watching to see how long it can last.

The good old 9V batteries. Long lasting and works 100% of the time. For the price, you'll beat the energizer bunny all day long.

I always purchased name brands for my microphones for yoga classes until I decided to try these for the cost. Well I here to tell you buy them they have lasted as long if not longer

The price was good, I actually tested each one out when it arrived with my multimeter and read fine. Stocked up on them for daylight savings when I change out my smoke detector batteries

Ordered on-line and received quickly along with the Simplisafe Security System I ordered. Ordered this multi-pack so I'd have replacement batteries available for when needed. Pleased with product..

Good batteries for a cheap price. Using in smoke alarm, cheap replacement for the ones that came with the alarm.

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

They work! Put one of these into a device that uses them, and it worked right away! Great option to have them available here.

I replaced all of my smoke detectors with these batteries and even use it when I'm playing paintball and for my stud finder. Great product and just as good as duracell and energizer.

I am tired of buying brand name batteries for premium prices. These batteries work so well and hold up to the other batteries for much less. These batteries will not disappoint,

Bought some on sale to use around the house. Admittedly, so far I've only installed one in a smoke detector - but it's been going strong for the last 4 months. Thumbs up!

I bought them at my local Best Buy store and glade I did. As premium batteries do not come at a cheap price any longer. They maintain their charge as the top of line ones do less the expense!

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