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

The PKCELL Carbon Zinc 9V batteries are the perfect, cost-effective solution for my home's essential low-drain devices. I exclusively use them in my smoke and carbon monoxide detectors, where reliability is non-negotiable. They provide consistent, stable power and have proven to be ultra long-lasting, giving me real peace of mind. While not designed for high-drain electronics like powerful toys or radios, their performance in smoke detectors is exactly what you want. The low self-discharge rate means they hold their charge while in storage, ready for when I need to perform my biannual detector replacements. Purchasing in this multi-pack makes tremendous financial sense, ensuring I always have fresh batteries on hand for all my safety equipment without last-minute store runs. For their intended purpose, they are reliable, affordable, and highly effective. I trust them to power my family's first line of defense, and they have never let me down. A highly recommended, no-fuss essential for every household.

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.

Works as they should.

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

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.

A couple of the batteries , made the smoke detector beep for low battery as soon as it was installed. One that I had installed in a smoke detector beeped low battery after only 2 months. Totally unreliable for something as important as smoke and carbon monoxide detectors. I now have to change them all out again in my rental apartments' after only 2 months as I can't trust them.

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.
