70% CAPACITY GUARANTEE: To be eligible for Promovec's

3-year capacity guarantee, if you register battery, must be registered via Promovec's website. The warranty covers a guaranteed minimum capacity of 70% for 3 years from the date of purchase. Registration must occur no later than 14 days from the date of purchase.

If a battery is capacity tested to less than 70% within the 3-year and any additional 5-year warranty period, Promovec guarantees to repair the battery so that there is a minimum capacity of 90%.

The following information shall be recorded:

If you do not have an e-mail address, the dealer can help with the battery registration and a copy thereof. After registration, an e-mail will be sent confirming the entered information. Please keep this receipt. The registered information is also stored electronically at Promovec A/S, so it can constantly be retrieved.

Should a complaint about the battery arise, please get in touch with the dealer where the battery was purchased. If the dealer submits the battery to Promovec A/S in connection with a complaint, the following must be sent:

If Promovec A/S cannot detect any fault in the battery or if the capacity test result is above 70%, Promovec A/S cannot approve the complaint. In this case, a diagnostic fee will be charged for performing battery tests, which your dealer can inform you about. A test report will be included as documentation when returning the battery.
