How many mAh are these in a smoke detector?

Beware this battery only lasts about three and a half months in our plain jane smoke detector. Then upon replacing it with a new one the new battery only had 7 volts. I then checked other batteries from the same pack and found another one measuring 7.3 volts. Experation date on bottom of batter is 12/2024. It's past the one month return window and Amazon says its too late. They wouldn't help and told me to contact the seller

Will these batteries leak?

The batteries come new and not working, read the reviews and see so getting to the point of a leak is probably not going to happen because the batteries are useless..

How many mA is this battery?

Typically 400 to 500 mah and will typically last about a year in your average smoke detector

When is the expiration date of the battery sold now?

There is an expiration date at the bottom of each battery, and the expiration date sold now is about 12/2024
