Assuming you are referring to the warranty on Honda's batteries in general and not just first Texas Honda, most Honda models have a 36-month/36,000 mile warranty on their battery. This means that if your battery fails within 3 years or 36,000 miles (whichever comes first), it will be covered under warranty. There are some exceptions to this rule though, so it's always best to check your owner's manual or with a dealership to be sure.
