works fine in smoke detector all week. will work for a year when it is time toc change

I was hesitant at first to buy this product. However, it was on sale--half price--so I thought I couldn't really go wrong. I use these to change the smoke alarm batteries and so far, they've been great and doing what they're supposed to do. It's also way cheaper than the name brands. I would buy these again in a heartbeat.

I often use this instead of name brand and I feel like they last just as long. They are a reasonable alternative.

batteries worked good on lots of childs toys and games and other items and remotes

Excellent price and package. Definitely a price saver

Needed some 9V batteries for smoke detectors and happened to see that these were on clearance at Best Buy. Read the reviews and decided to get these rather than the major brand I normally used to get. So far, very impressed with the quality. I'm going to try the other size batteries after getting these.

I have 9V batteries for 10 years at a fantastic price

Great battery for this price, works well without any issues. Would recommend to others.

great value. I keep them in sock because I cant find this value any where else

Bought these on sale to use in my smoke alarms at home. Having many in my house, this is a great value compared to other brands.

They seem to work, first set has not died yet. No complaints.

Great batteries at a great price and nice variety!

Great batteries. Nice storage container. Good price

No issues so far. These seem to work without issue.

Needed to get alkaline 9-volt batteries for my kids and saw the Insignia brand for sale. I have never purchased them before but due to the value and cost, I thought it was time to try them. For the ones that we've used so far, they are working fine. I have not seen any less performance or less run time so far. Thanks.

I have been buying Duracell batteries for years. I have had several incidents of batteries going bad, leaking acid into my remotes, game controllers, etc. and actually damaging a remote to the point it no longer functions. Best Buy recommended the Insignia Batteries so I made the switch and will never go back to Duracell.

I bought these because the brand name i normally pay for have been having corrosion/leak problems. I don't know why. Its not like I've been doing anything different as far as I can tell. So far these haven't had that problem. They weren't exactly cheap but neither were the brand named ones

Convenience 4 pack of batteries.. never tried this brand not to bad the amount of money I pay for it..

Always replacing batteries in smoke alarms in rental properties. Now I will have plenty on hand at a good price.

Great battery replacement for anything that use a 9V. works the same as brand name. Best money that you can buy.
