I see lots of reviews with the battery dying early. Is there an expiration date on the package somewhere, that I can check, before I even install?

Asked by: SAV
I don’t remember seeing a date on box. However there is a “whit tab” on the battery/ unit that you pull to “engage” the battery. ( like the tab you see on most items that light and flash) We wrote install date on the side of unit.
