Pro-Rated Warranty Explanation The customer pro-rated charge for a replacement battery is calculated based on the Retail Price shown on the website (this does not include any discounts given at the time of purchase). A “warranty cost per month” is calculated by dividing the battery price by the number of months in the offered warranty. To determine the replacement battery cost, the warranty cost per month is multiplied by the number of months the battery was in service. Months in service is determined from the battery purchase date.
