When it comes down to car batteries, there are a few different warranties they will be covered under. If you’re wondering whether automotive batteries are covered under warranty, it’s important to consider these various warranties. The coverage periods may overlap if your battery is covered under multiple warranties.

When purchasing a new vehicle, the retailer will provide you with a bumper-to-bumper and extended warranty. The bumper-to-bumper warranty is comprehensive and covers most original equipment manufacturer (OEM) parts for three to five years, while the extended warranty takes effect when the initial warranty expires.  

Under most bumper-to-bumper warranties, the car battery installed in the new vehicle will be covered. The specific warranty regulations will vary between different manufacturers. Generally, the new battery will be covered by this warranty if the battery is defective or damaged.

Unfortunately, car batteries are not covered under most extended manufacturer warranties due to being classed as “wear and tear” components. Brake pads and tires are also parts that are typically excluded by extended warranties on new vehicles.

Luckily, your car battery will also be covered under a manufacturer’s warranty, which also applies to any replacement batteries you purchase. Overall, car battery manufacturer warranties typically cover the battery for 24 months or 36,000 miles from the date the battery was purchased.

Since the manufacturer warranty starts from the date of purchase, you’ll need to have the original receipt to claim against any of these warranties. To verify that your battery is still covered under warranty, you can refer to the receipt or check the date printed on the top of your car battery.

While car batteries are covered under warranty, the warranty period and terms will vary according to where you purchased it and who manufactured it. As a rule of thumb, the more comprehensive a car battery warranty is, the more the battery itself will cost. The higher price is also likely due to higher quality materials being used to construct the battery.

Regardless of which car battery model and brand you have installed in your car, it will be covered by one of three warranty types. In the following section, we’ll outline these three car battery warranty types that consumers will encounter.

Types Of Car Battery Warranties

Overall, three types of car battery warranties are available today: a Free Replacement Warranty, a Pro-Rata Warranty, and a Composite Warranty. By understanding these warranty types, consumers will better understand the coverage provided by their automotive battery warranty.

Free Replacement Car Battery Warranty

Under a Free Replacement Warranty, your car battery will be covered for a free replacement if it has a defect, malfunctions, or stops working. Free replacement batteries will be covered by the original warranty and will not provide a fresh warranty.

Furthermore, it’s important to note that different manufacturers will stipulate conditions regarding how the damage to the battery has occurred. Under certain conditions, such as willful or negligent damage, the manufacturer may not cover you for a free replacement.

Pro-Rata Car Battery Warranty

Under a Pro-Rata Warranty, your car battery will not be covered for a free replacement. However, under this type of warranty, consumers will get a calculated discount on the replacement battery in the event of a broken or defective car battery. A Pro-Rata warranty is calculated from the date the battery was sold. When purchasing a replacement battery under a Pro-Rata Warranty, a new warranty will be activated.

Composite Car Battery Warranty

Many manufacturers offer a Composite Warranty on car batteries, which is a combination of the previous two types of warranties. Under a Composite Warranty, a car battery may be eligible for a free replacement for the first half of the warranty period, followed by Pro-Rata coverage for the remaining warranty period.
