I have blister packs of ECR1216 lithium batteries. They are identified on the back of the packages as 39800 02288. Preceding these numbers is a half size 0 and succeeding these numbers is a half size 2. Centered on vertically on the right are the letters SA. Can you provide a manufacture and/or an expiration date for these batteries based on this information?
