Customer Ratings & Reviews

They worked as expected. Replacements older for smoke detectors and another device that needed a 9v.

Great packaging and arrived right when promised. Product lasts a pretty good while.

Overall for a one day sale at the price paid you can not go wrong. Perfect for smoke alarms!

I always buy Insignia brad batteries when I can. They last as long as the expensive brands

Bought these batteries when they were on sale. Excellent purchase considering Best Buy's deal of the day. Good to update all the batteries in smoke detectors in the house. Good luck finding good alkaline batteries cheaper than these

Wonderful product quality for the money its worth for the price long lastin battery

Great batteries at a great price. Very happy with these batteries

These Insignia batteries are great, they serve the purpose and they are a fantastic value.

I use this for my smoke detectors and has been reliable so far. Certainly good to have stocked up once those guys start chirping.

9v batteries r expensive so getting these are great substitutes. I use in smoke detectors n lasts long time. Thx BB

I have been using these Insignia 9V batteries for several months and all of them have been great so far.

These batteries work just fine, and with how expensive batteries are, the price was excellent! no complaints.

I use these batteries mostly as replacements for my smoke detector batteries. Work great and have been long lasting so far.

These are great batteries for the money and work just as good as Duracell or Energizer.

Battery pack was a fantastic deal-of-the-day bargain. Snap these up when they pop up.

I put these in my fire alarms. They seem to last and they are at a good price when on sale.

You can't go wrong with twelve 9v batteries. I use these in my smoke detectors and always have backups when I need them.

It's 4:00 pm on a Tuesday. Your sound engineer friend has complained to you for the "last time" about forgetting to unplug the line cables from his Big Muff bass pedal. To make up for the currently five blown 9 volt batteries, you decide to purchase a 12-pack of Insignia batteries. The end resulted in a happy sound engineer/bassist, but who really cares if a bassist is happy lol amirite?

First time being the 9V version of these batteries, but if it is anything like the AA or AAA then they will be great.

We change our smoke detector batteries twice a year. We also use battery back up in our alarm clocks which require a 9 Volt. These batteries are very economical particularly when we only use them for 6 months.
