I have used Enegizer batteries in business and industrial moderate and high drain devices for over 40 years. They outperform ALL other alkaline batteries on the American market by a minimum of 3 to 1 service life. Some like the copper top ones are pitiful in comparison! The copper topped ones last about 5 to 7 days in a pager, the Energizers last an average of 3 weeks in same pager! Unless you use Lithium batteries, there is no comparative alkaline battery that even comes close to competing with Energizer.

I use these in our smoke detectors and they are good reliable batteries. I use the good name brand and avoid the cheap off brand ones and have never had a problem.

The 9 Volt DC Batteries work fine. It's that time of the year when all the Smoke Detector batteries need to be replaced.. Buying a 12 pack is the most cost efficient way I have found to resolve this problem plus have a few in reserve for the unexpected that always seems to pop up when you have used your last battery. .

I don’t think there is nothing wrong with the batteries because I hook one up to my multi meter and the voltage was good. However, I think the current output is too low for my first alert smoke detectors. I ended up buying some Duracell and had no problems.

I have some freezers that use 9V batteries. These are handy to have on hand. I really don't like having to listen to a freezer beep constantly until I can get to the store to buy a new battery. Thank you.

Thank you for the note reminding us about resetting the smoke alarm. We looked it up on YouTube and solved the beeping problem. We also like the plastic cover for each battery. Overall great quality and value. Highly recommend.

Great deal on 9-volt batteries. These were purchased for use in smoke detectors. They seem to be genuine Energizers, but only time will tell how long they will last. So far, so good.

In searching for smoke alarm batteries I kept running into $10.00 per for a 10 year battery. These industrial batteries were among those recommended for smoke alarms. I bought them and they work great, far less per battery for 5 year life span and beeping is gone. Highly recommend.

Energizer Industrial Batteries are good batteries. I use these in all my smoke detectors. I change batteries once a year even tho they still have a good charge in them.
