The right size battery for my smoke detector Quick fix to my issue! Curbside pickup was super easy!

Got these for exercise equipment. They will hopefully last long enough to justify the cost per battery vs battery life decision

I got a bunch of batteries for a decent price, they work in my smoke detector's but I have not had them that long so I don't know about the life span.

Have not yet had the need to use these batteries. Based on the AA and AAA I have already purchased and used I am sure they will be just as good.

I buy these Insignia batteries for low drain devices such as remote controls etc and they hold up pretty well. Don't expect them to last like a Duracell when using them in a high drain device like remote controlled toys.

Item is used to save time settings in clocks in case of a power outage. Works great so that time does not have to be reset after a power outage.

Haven't used them yet but have been pleased with other Insignia batteries.

They are batteries - nothing more - nothing less. Use for smoke detectors or in my grandsons case a metal detector. A very good price when on sale.

Nice riding board. Great for getting around town or just riding for fun. Easy use. Even enjoyed by the older generation.

Worked as advertised. Purchased to go into christmas toys. worked well

For 1/2 the price of the brand name batteries these are great. So far they are lasting as long as the brand names for my use.

These batteries are marked at a cheaper price but they work just as good as the name brand. They may not last at long but they last awhile in my opinion. Make sure to get them on sale though because they do drop the price occasionally.

Seems like when one alarm battery goes out they all do, bought a pack of these saved myself time on going back and forth to the store.

Previous experience has shown good service life for this Insignia 9V battery when compared to other brands. Best by date is 4 years away, not as generous as for other brands. Only buy these when on good sale!

I usually buy a name brand item but this seems to be just as good. This is the first time I tried Best Buy's brand.

These batteries seem to be working well.I put them in hardwired smoke detectors as a backup.

These batteries are great, and they even work in my smoke detectors. I was a bit worried, because I read online that the batteries might not have the same dimensions as the Duracels or Energizers, but they work great in my smoke detectors

I like to be prepared for an emergency, and my desk clock uses this type of battery.

Just as good as name brand you would find with Duracell or Energizer

They work for how long I don’t know but they are used for fire alarms so they do the the job.
