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!

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.

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

Works as they should.

Good price

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.

Great batteries. They were individually wrapped which made storage easy. Can't beat the price!

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

These batteries work and last as advertised!
