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

I bought these mainly for the smoke detectors I have around the house. For low-power stuff, they work just fine, no issues so far. They’re definitely more affordable than other name brands, which is great if you need a bunch at once. Just keep in mind these are zinc carbon, not alkaline or lithium, so they’re not meant for high-drain devices. I wouldn’t use them in anything that needs a ton of power or constant use. They came well packaged, none were leaking, and I appreciate that they’re made without toxic stuff like mercury or lead. Good deal for backup or light use, but probably not your go-to for heavy-duty gadgets.

These PKCELL 9V carbon batteries worked exactly as expected and arrived well packaged. I used them in smoke detectors and a few household devices, and they powered everything on right away. Shelf life seems good, with no weak or dead batteries out of the box. They provide steady performance for everyday, low drain electronics. For the quantity and price, this pack is a great value. I’d gladly buy these again to have on hand for use around the house.

Old school batteries, the old Eveready Carbon type.. not Alkaline. I use these for guitar pedals like fuzz boxes and vintage pedals, supposedly they sound better ? I doubt it, but they’re cheap and they seem to work well, no issues with them at all

Purchased these for smoke detectors. They last just as long as any other 9V battery and they are much cheaper! I have and will continue to buy them again.

Great price and they last a long time. I change all of my detectors at the same time to avoid that annoying chirp. Under 7 dollars to do all of them at once. Problem solved.

Good value and price for these. Always good to buy every now and then. Have no complaints with them. Use for detectors and they seem to last for a good while.

Batteries perfectly working , And at very low price.

These are Not "Heavy Duty" batteries. Other reviewers recommend them for smoke alarms, but these batteries lasted less long in my smoke detectors than other batteries including Amazon Basic brand. And one of the batteries in the 10 pack was Dead On Arrival.
