PKCELL 9V Batteries, 10 Pack 9 Volt Batteries Carbon Zinc, 9V Battery for Smoke Detector, Alarms, 6F22 Square Battery

These 9V batteries work well for smoke detectors and other low-drain devices. They’re affordable, easy to use, and a good value in a 10-pack. Great for everyday household needs!

Great value, seem to last a long time, As I mentioned in the title some cheap batteries feel like they are half full. These have the feel of a full battery. I use them in my multimeters, and they perform as well or longer than than the ones I grab off the shelf at a store.

These batteries work as well and last as long as the name brand and and are a lot less expensive.

I bought these for a tens unit because they were cheap and I go the batteries fast. These lasted me a lot longer than I expected. I would recommend for an off brand they hold a charge longer than expected.

I like the idea of not having to change the battery in my alarm smoke detectors but once a year. Yes these keep the strength all year long

For these batteries to not be a name brand, they have lasted very well. Got them for my automated trash cans. They have lasted very well! I'm satisfied.

Works as they should.

I’ve bought these a few times for smoke detector replacement. Last batch I purchased hasn’t been great. A few failed within a couple months and another that reads 9.5v chirping. Going to look for another brand.

Great product. They work well. Good price.

The price is pretty reasonable and the last for an adequate period of time.

One battery received damaged

i bought a10 pack of 9v batteries, unfortunately not one of the battery had a charge. All of them had zero charge. i would think that Amazon would check the products that they sell. I am disappointed. thank you Edgar L'Ecuyer
