What does the date on my battery mean?

If your battery is a "Cardinal" or "Heine" brand, the date on your battery is the expiration date.

If your battery is a "Supreme Power" brand, the date on your battery is the manufacturer's date. The warranty of Supreme brand batteries is 2 years from the Manufacturer's date.
