We will determine the date of purchase in the following order of priority, if and as available: (1) the unit specific tracking data on our automated purchase tracking system (not applicable to batteries purchased before June 22, 2009); (2) your sales receipt; (3) the punch-out dater on the battery case. If none of these dates are available, the warranty is void. Muchas gracias!!" to "Muchas gracias!!"
