I am totally amazed to see 10 plus year old batteries being sold online with little or NO info as when they were made or put in service.

Some reputable sellers put a guesstimate on year the batteries were made. But major sellers skip this very important information. Surely they know the details and surely they are not intentionally skipping this?

I wonder the battery manufacturers don't have to put in made on date on the cells itself?

The flipping SALT at the grocery store as an expiration date, but a Li cell/batt has NOTHING.
