An original 12-volt battery for a conventional Lexus is covered by the New Vehicle Limited Warranty for 48 months or 50,000 miles, whichever comes first. An original battery for a hybrid Lexus, on the other hand, is covered for 10 years or 150,000 miles.
Lexus is well known for manufacturing high-quality and reliable luxury cars. But even the most dependable cars will sometimes break down. If the battery in your Lexus wears out sooner than anticipated, you’ll be left without a working vehicle. Depending on how long you’ve had your Lexus, the cost of a new battery may be covered by your warranty.
Navigating the terms and conditions of your battery’s warranty can be a major hassle. Fortunately, the car insurance
super app Jerry
has done all that warranty research for you! In this article, you’ll find everything your need to know about your Lexus battery warranty and how to save on your Lexus insurnace costs
. What’s the warranty on a Lexus battery?
When you buy a new Lexus, it will be covered by their New Vehicle Limited Warranty. This warranty includes coverage for your battery and stays in effect for 48 months or 50,000 miles, whichever comes first.
If your battery fails or becomes faulty during that time, Lexus will cover the cost to repair or replace it. If you replace the battery
with a Lexus Genuine battery and have it installed by a Lexus technician, the replacement battery will be covered by its own warranty for 24 months. Keep in mind, the New Vehicle Limited Warranty only covers conventional 12-volt batters, not hybrid batteries. Lexus hybrid batteries have their own warranty coverage called the Lexus Hybrid Battery Warranty. This covers the battery for 10 years or 150,000 miles.
Here’s a breakdown of Lexus’ warranties:
| | |

Signs your Lexus battery needs to be replaced
Before you replace your Lexus battery, you’ll want to make sure that it doesn’t just need a jump-start
. To help you know the difference, take a look at these common clues that a battery is faulty: The battery light is on
: Your Lexus has a specific warning light to alert you when your battery is not working properly. If it comes on, have your battery looked at by a Lexus technician. No power to lights and horns: If any of your car’s electrical equipment is not receiving adequate power, there’s a good chance your battery is defective.
Engine cranks without starting: One of the most obvious signs of a malfunctioning battery is when the ignition will not work.
Swollen battery case: This is one of the more serious issues your battery can have. If you notice that your battery case is swollen, do not attempt to start your car. This could result in an explosion. Leave your car immediately and have a trained technician replace the battery.
Leaking battery: If your battery is leaking, it will definitely need to be replaced.
How long your Lexus battery lasts will depend on how frequently you drive it, how well you take care of it, and the weather conditions in your area. On average, most conventional 12-volt Lexus batteries will last about four years. The Lexus hybrid batteries should last a while longer and run for 100,000-200,000 miles.
How to extend the lifespan of a Lexus battery
The best way to maximize the longevity of your battery is by following the Lexus recommended maintenance schedule
. If you’re looking to go above and beyond the average, you can use these tips to squeeze a few more miles out of your Lexus battery: Avoid frequent short trips. When you go on a short drive, you don’t give your battery time to recharge. The longer you drive, the more it recharges. This will keep the battery from chronically sitting at a low charge, which could shorten its life.
Don’t leave your car unused for long periods. Leaving the car dormant will slowly drain the battery and ultimately reduce its longevity.
Double-check that your lights are off. When you get out of your car, remember to always shut off the lights and any electrical equipment that could drain the battery.
Scrub your battery terminals. Keeping your battery terminals clean and free from debris/grime is key to extending its life. Baking soda works well for this chore.
Steer clear of extreme heat. Most people know that excessively low temperatures can be bad for your battery—but extreme heat is even worse. As much as possible, keep your car out of excessively high temperatures.
