Question Advise on Powering a LED using a CR2032 battery

[Cycloner]

Hi, I'm new here. Sorry if this is the wrong forum.
I bought some new CR2032 batteries and tested them on my volt meter and I get 3.36 volts. Why is this? shouldn't it be 3volts?

Also I tested the volts on a socket and I get 124volts and not 120volts.

Is this normal. or is my volt meter not accurate?

if its normal. How do I power an led with this in mind and using the proper resistors.

Thanks in advance.
Chris
