What’s the current expiration of the batteriesyou are selling?

Mine were older batteries. They only had 2- 2 1/2 years left before they expired. They were not fresh batteries.

Seller, what is the current expiration of the batteries you are selling? I would recommend updating amazon your lot of batteries expiration changes

The Ones I Ordered Were 2021 . Hope This Helps.

Anyone know how long these laat in a smoke detector?

Fire Dept. recommend changing batteries on smoke detectors when you change "Spring Ahead, Fall Back". I change my batteries once a year at Christmas time so I remember when I did it last. I don't wait for the smoke detector to tell me in the middle of the night by beeping so the answer is over a year IF you wait for beeping.
