Super Heavy Duty 9V Battery

The Eveready Super Heavy Duty 9V battery worked exactly as intended. I bought it to replace the battery in the smoke detector in my studio unit, and it powered it right up without any issues. The battery itself is straightforward and reliable. Honestly, the hardest part of the whole process was climbing a 10-foot ladder to reach the detector, not installing the battery. Overall, it’s a simple, dependable battery that gets the job done when you need a quick replacement for household devices like smoke detectors. No complaints.

Great price

All you’d expect

worked great

I used it in my multi meter. it seems good but only time will tell if it holds up and lasts long

This battery was for my smoke detector. Has it made it sound sense I’d like the price.

Dead battery I bought this battery for a CO monitor as the monitor was chirping to replace the battery . I put the new one in and it continued to chirp.

Seriously a review for a battery well here's my review my smoke detector was making a loud annoying beeping noise that would not go away I ordered this off Amazon got it the very next day had a very fair price probably cheaper than going to Walmart Took the old battery out of the beeping smoke detector put the new battery in and Instantly the smoke detector quit beeping. Seriously how do you write a review for a battery?

Needed it for our fire alarm. Worked.

Works fine in Ottawa, Canada as the battery for the garage doors locating outdoor, with -20 at night

I bought this specifically to replace the batteries in my fire alarms and they worked perfectly. They were super easy to install and the fit was exactly what you’d expect from a standard 9V. Buying these in a pack is so much cheaper than the local hardware store. It’s a small price to pay for peace of mind!

As advertised

Pros: battery shape fits on the garage door keypad, sufficient voltage
