As the most popular EV manufacturer, Tesla sets the standard for electric vehicles everywhere. Tesla owners may be rejoicing over never needing another oil change, but they still have to keep up with routine maintenance needs…like their car’s battery life.

If your 2013 Tesla Model S needs a new 12-volt battery, don’t panic—we’re here with the guidance you need! We’ll cover how much you could expect to pay for a new 12-volt battery, how often you’ll need a new one, and how to extend the life of your next one.

How much does it cost to replace a 2013 Tesla Model S 12V battery?

Replacing the lithium-ion battery in a 2013 Tesla Model S could cost up to $450. If you’re just looking to replace the 12V battery, that will cost an average of $250 and a maximum of $450. The battery itself, however, may only cost up to $100.

Every Tesla comes with two batteries: a large, powerful (and expensive) lithium-ion battery and a standard 12-volt battery (like the ones found in regular gas-powered vehicles). The larger lithium-ion battery powers the motor(s) and moves the car, while the 12V battery controls the interior features of the car, such as the touchscreen.

The 12V batteries are covered under Tesla’s New Vehicle Limited Warranty, which lasts eight years or 50,000 miles, whichever comes first. If your Model S pops up the “service 12V battery” notification and your Tesla is still covered, the service should be free of charge.

If your Tesla’s warranty has expired, there’s always the do-it-yourself route. You don’t need to be an

electric car mechanic

to change your Tesla’s 12V battery, but you will need a few basic tools and a whole lot of confidence. Just make sure you buy the same type of 12V battery as your old one.

Of course, if this process seems too daunting, it’s better to play it safe by getting a Tesla-certified mechanic to change your battery. You can either drive to your nearest

Tesla Service Center

or request for them to come to you.

Can you put a new battery in an old Model S?

Newer Teslas use lithium-ion 12V batteries, but your 2013 Model S requires a lead-acid battery—the AtlasBX/Hankook 85B24LS 12V 45Ah battery, to be exact. While the 2013 Model S may be compatible with a new lithium-ion battery, it’s best to let the professionals determine which type you need. Using the wrong type of battery in your Model S could cause expensive damage that’s definitely not covered under warranty.

How long does a 2013 Tesla Model S battery last?

Unfortunately, the 12-volt battery is one of the parts in a Tesla with the shortest lifespan. In older Tesla models, they’ll last between three and five years. Lead-acid batteries, however, may need to be changed more frequently.

If the 12-volt battery in your Model S is draining quicker than it should, you may be able to extend your battery life with a few simple hacks:

Update your software. Tesla has released a software update that attempts to remedy this battery-draining problem, so having the current software version may keep your battery life in check.

Keep your battery charged. Letting your main battery’s power get too low also shortens the life of your 12-volt battery.

Limit electronic use. Your 12-volt battery powers everything electronic within your Model S—including the car locks, lights, and windows. If your motor isn’t running, try not to use electric components unless it’s absolutely necessary. Forgetting to turn your overheard lights off overnight will kill your battery just like it would in a regular vehicle!
