Has anyone bought this for Comcast/xfinity door sensor? And does it work with it?

I bought for Xfinity window sensor and battery only last about 3 months. I have switched this battery 2 other times and none lasted longer than 3 months. Window does not get opened at all. The battery that came with sensor upon installation lasted 3 yrs.

How do we know the date of manufacture (i.e. the age) of the batteries?

The manufacturer date is not printed on the batteries or package. These batteries are specific for cameras, watches and calculators per the packaging pictures. I found them useless for remote garage door use from an iPhone.. They lasted about two weeks compared to six months with other batteries I’ve used. I give these batteries one star.

Will this work for tea lights?

They will work if the battery in the tea lights are the same reference.
