I've had the opposite problem. I was reading a lithium battery package many times, frustrated that I could not find the expiration date. I finally realized that "2032" was printed as a year and was not an alternate size code.

CR2032 is a battery size, sometimes the CR is dropped due to the small size of the package.

But 10 years is also the rated lifetime for CR2032 cells. Those made in 2022 will definetly still be good to use in 2032. I've had some last as PC CMOS ram backup cells since the late 90's and they are not rechargeable, nor being charged in the system they are in.
I know, hence my brain ignoring the marking for the longest time. This was a package of AA sized batteries, not coin cells!
