Bought these for the battery powered smoke detectors. It’s been over 9 months since I last replaced it and it hasn’t chirped since. They’re easy to find

I can't tell you how ama this battery is. The last time I bought one was 8 years ago and it's still going, all my smoke alarms have them in and they're still going strong too and that's been about 5 years

My husband only uses these batteries for his paintball gear as he only trusts this brand to not ruin his gear. He lives the consistency and longevity. Never any issues.

The voltage is perfect for my son's toy cars, and it lasts a very long time. It's also easy to use. It works for remote control cars; I forgot to buy batteries for a while!

Very reliable and long lasting

I’ve been using these in my smoke detector and they’ve lasted really well.
They hold power for a long time and don’t suddenly die out.
I like that they feel reliable, especially for safety devices.
A little more expensive, but I trust these more than cheaper brands.
