Customer Ratings & Reviews

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.

Ordered as deal of the day because of price. Reordered at regular price because of longevity of batteries. Outlast all 9v batteries we have used. Highly recommend.

These 9 volt batteries are holding up well after using them for a month or so. Would definitely say are a quality battery at a great price. Will buy again!

I was able to get these on a deal of the day at a great price, and just in time for when all my smoke detector batteries needed to be changed!

I don't know why 9v batteries in general are so expensive, but these insignia multi packs are a great deal and keep all of my scales and smoke alarms running all year.

Great batteries. They seem to last as long as the date says. Very economical too. Would recommend them.

Purchased these for a few devices and didn't want to pay the same price for 4 batteries. They work well and seem to last as long as the more expensive brands.

These batteries were actually better than anticipated they definitely cost far less than anywhere else especially Walmart, and the actual battery life itself was more than adequate.

These came in handy christmas morning when we needed batteries for the grandchildren I love that there was a mixture of batteries of most sizes needed for there toys

This is a great choice for batteries, used them in an irrigation controller and they lasted for multiple seasons.

Insignia batteries are the best! Top notch product. Never have had a defective battery.

I needed 9 volt batteries for my smoke alarms and these were such a great deal. I bought the 12 pack for the price I would normally pay for 3 or 4 9 volt batteries.

Bought and tried it. Works great and very nice item

We all need batteries. Best Buy stocks good batteries at good prices, and you don't have to buy a package of 50 like in other big box stores.

These are excellent batteries for my smoke detector. They have a long life and don't need to be replaced as often.

I always buy name brands batteries but they beat buy brand was on sale and I got it. As of today going strong

These are a good price, and come with the bonus storage case. They're a good price, especially on a Deal of the Day. A good pack for smoke detector replacements.

I have used these in the past in smoke alarms and although they still are going strong I still change them out every 6 months and this 12 pack is ideal

I just needed some batteries for my smoke detectors. They seem to do the job.
