Every new battery comes with a warranty, but the number on the label does not tell the whole story. Here is what to look for and what to keep.
Free replacement and prorated coverage
- Free replacement means that if the battery fails within the period, you get a new one at no charge for the battery itself.
- Prorated coverage means you get credit toward a new battery based on how much of the warranty period has passed.
Some warranties combine the two: free replacement for a set time, then prorated after that. Labor to install the replacement is usually not part of a battery warranty.
Listed warranties on the batteries we install
| Battery line | Listed warranty |
|---|---|
| Duralast standard | 2 years |
| Duralast Platinum AGM | 4 years |
| Duralast Heavy Duty | 1 year |
These are the warranty lengths listed by the retailer at the time of writing. Terms can change and depend on the exact product, so we confirm the warranty for your battery with your quote.
What can void a battery warranty
- Physical damage, such as a cracked case or broken terminals.
- The wrong battery for the vehicle, or a battery used for something it was not built for.
- Charging system faults, such as a failing alternator, that damage the battery.
What to keep
- Your receipt or invoice, with the date of installation.
- The battery’s part number and date code, printed on the label.
If a battery we installed gives you trouble, call us with your invoice and we will explain the next steps for that product. Warranty coverage depends on the product and on eligibility.
