what are the dimensions of these batteries ?

Can't pull up video, so I write...Is one CR2032 the equivalent to two CR1620 lithium button batteries, both in watts and dimensions for led light use?

If I used these for fairy lights I have how long would they last

Lasted about 24 hours, after 24 hours, the lights were dimmed, but it can still maintain a dim light, and the battery capacity is much larger than other batteries. Or you can spend a little more money to buy PETVAY's fairy lights (pack of 12) outright, we give away 24 batteries.

What is the expiry date?

The data on my order was 10/2024. Today is 8/12/2022. I use a ZTS MINI-MBT cell tester, which experience has shown to be very accurate. On the four cells tested tonight, all tested at 20%. I have a small clip light that uses two cell,and was trying to replace the used cells. The light is held together by two very small Phillips screws, which meant I had to purchase the right size screwdriver to open the case. After all that joy, I was very disappointed that the light would not turn on with the 'new' cells. That is when I drug out my ZTS and found that my replacement cells were essentially dead. These cells have been stored at room temp and not exposed to any extremes of temperature, so they should still be good, given their stated expiration date. I will looking to a different vendor for my replacement order.
