Warranty terms: 8 years / 100k-150k miles, whichever comes first depending on model
The battery of every new Tesla is protected by the Battery and Drive Unit Limited Warranty which is included in the standard New Vehicle Limited Warranty. 
Tesla warranty coverage means that, as long as your Battery and Drive Unit Limited Warranty period is still active, your original battery will be repaired or replaced for free if it is defective—note that defects are different from damage due to normal use.
Now, the exact number of miles a battery is covered will vary depending on the specific Tesla model you have. Here’s a table with more info.

Tesla batteries are estimated to last 300,000 to 500,000 miles

Tesla CEO and co-founder Elon Musk claims that the average Tesla battery can be expected to last between 22 and 37 years or 300,000 to 500,000 miles. Since the oldest Teslas have only been on the road since 2008, there isn’t any hard data to support his claim yet. 

Signs your Tesla battery needs to be replaced

Just because your battery is not powering your car properly doesn’t necessarily mean you need a new one—the battery may just be dead! In this case, you can simply
jump-start
it. 
Here are key signs that your Tesla battery might need to be completely replaced:
  • The battery light is on: There is a warning light that will appear on your touchscreen specifically to notify you that there is an issue with your battery. If you see this light come on, it might be time for a replacement. 
  • No power to lights and horn: If your battery is on its last legs or has low battery capacity, you’ll notice that it is struggling or failing to provide power to the electrical systems in your car such as the lights and the horn. 
  • Engine cranks without starting: Without adequate power from the battery, your car cannot start. If your car
    struggles or fails to start
    , you might be dealing with a defective battery.
  • Swollen battery case: If you notice that your battery is swollen, you should call for towing immediately. This is a major safety concern as swollen batteries can explode. You should not drive a car with a swollen battery for any reason. 
  • Leaking battery: This is an obvious sign that there is a serious issue with your battery. It will need to be replaced ASAP. 

How to extend the lifespan of a Tesla battery

Extend the life of your Tesla battery by following these simple guidelines: 
  • Avoid frequent short trips: Your battery recharges while you’re driving. Short trips drain the battery without giving it adequate time to recharge.  
  • Don’t leave your car unused for long periods: If your car sits for too long, it will struggle to hold a charge.  
  • Double-check that your lights are off: Always make sure everything is off and nothing is draining your battery before you get out.  
  • Scrub your battery terminals: Prevent corrosion from accumulating by scrubbing your battery terminals with a toothbrush and baking soda. 
  • Steer clear of extreme heat: Minimize your car's exposure to extreme temperatures, especially heat. 
The Tesla battery warranty covers
car repair
costs during the warranty period, which is quite generous for electric vehicles. 
While there are some exclusions (like normal wear and recall advisories), your electric car may still benefit from an extended warranty or the Tesla extended service agreement for peace of mind—just see if
roadside assistance
is already offered under your existing warranty agreement.
Ultimately, Tesla vehicles are great cars that can last a long time with proper maintenance.
