Customer Ratings & Reviews

I needed some batteries for my smoke detector went to my nearest Best Buy and purchased these they work well.

These are always a great deal when they are on sale. Great time to stock up on them when needed. Long lasting!

I have three kids. That means a lot of toys that need batteries. These cheap batteries have saved me more times than I can count.

Great batteries. Why pay for name brands when these work just as good and a lot cheaper.

I love these batteries they are great to have a bunch around the house because I use a lot of them for Battery operated candles etc.

Great deal for the price. Appreciate the plastic case Insignia batteries come in, keeps batteries that roll from rolling!

Although we don't use 9 volt as much as other batteries, our smoke detectors use them and we change them at least once a year. BEST DEAL AROUND!

These batteries are sold at a great price, especially when on sale. They have been terrific for all uses except electronics like calculators that use a lot of energy. I have purchased every size in this brand and have been very happy with them.

Seem to last just as long as bigger named brands. Used these in fire alarms & so far so good.

Great batteries at a great price, same as duracell or energizer just a lot cheaper, thanks best buy!

Needed new batteries for my smoke detectors and these were a nice price for 2 of them

These were great batteries for the price. Not sure of how long they'll last but couldn't beat the cost for a 12 pack. Perfect for my smoke detectors.

Seem good. I tested in a meter when I got them and all were fully charged. Only time will tell if they last as long as national brands.

Bought these for my guitar effects pedals. They last for a long time (a full week in my Wah pedal) Ready to buy more!

Tthese are less expensive than Energizer batteries. However they work and last as long as Energizers.
