We offer a one-year warranty for manufacturing defects on all products from the date of purchase. During this time a defective battery may be returned for a replacement of the same product. This warranty does not cover batteries that are defective as a result of improper installation, charging, or other abuse and misuse, and we reserve the right to inspect and/or test any battery before issuing a warranty replacement.
Most batteries are also covered by a manufacturer's warranty. Manufacturer warranty information can be found on each battery's product page.
