i use the batteries all the time never had any issues, great for garage opener

Best Buy battery for replacing power source in my smoke detectors

Great buy on Deal of the Day. Hard to beat the price and quality. These batteries seem to last as long as the major brands.

I bought these as a deal of the day to use in the fall to replace the old ones in my smoke alarms. They have worked well before and I couldn't pass up the price.

This is a good deal for the quantity and price it comes for. However, one of the batteries didn't work at all right after we took it out of the box. But besides this one defective one, the remaining batteries we have used so far seem to work well, and they are quite lasting.

Was looking for some RC car 9V batteries. This may be too many, but a great deal when purchased on sale. They work fine in the controllers and last long in this use.

Excellent quality battery. Lasts just as long as those name brand batteries. Very reliable and would definitely recommend.

These batteries cost less than other brand name batteries. But these batteries also have just as much power as others.

Buying batteries can get expensive so I love that Insignia has an affordable option. I got these batteries to use in all the smoke detectors in my home and they've worked and lasted as long as the brand name batteries.

These worked well for my replacement batteries on my smoke alarms. I even had 1 left for my garage door opener.

I bought these to replace in smoke detector. Cheaper than buying the expensive name brand batteries and works as great.

Great value. I never tried insignia batteries before but I would definitely buy again. As good as any brand

This was a good deal. Always need 9V for the home, except I wouldn’t buy this size pack again. Not using them as fast as I thought.

When these go on sale they are a pretty good deal for 9v. Only have a few things that use them, and never seem to have them on hand when I need them. Now I am stocked up,

Batteries are very good quality. In my experience these work just as well as the name brand batteries which cost more.

We will always purchase when they are on sale. Preparing for the next power outage, storm or zombie apocalypse

The cost of 12 batteries was less than a 2-pack of the Energizer or Duracell batteries. I keep these on hand to make sure a smoke alarm never goes down.

These work just as good as the name brand batteries and you don’t have to pay the higher price.

Works great in my smoke detector. Got them on sale for buy one get one free. great deal

These batteries were a real bargain. These are the 9V batteries you need for important household items such as smoke and carbon monoxide detectors. We received the batteries quickly when we really needed them for our smoke and carbon monoxide detectors. The school is out on the batteries long-term performance, but so far, so good.
