I forgot my smoke detector needed batteries!

I have used these batteries for my smoke detectors many times and they seem to work the best from the other competitors. I have only had a few that didn’t seem to last as long as most but overall, these batteries will keep annoying smoke detector beeps away!

Value and functionality review
on July 1, 2026
Posted by: jeanellyi
This battery is very easy to install. Packaging is easy to rip off and ready to use. It's lightweight battery. I love energizer max as their batteries last way longer. Great use will always use this as long as it's available.
