How Long Do Hybrid Car Batteries Last?

Toyota Hybrid Models in City


Is a hybrid something that’s in your future in Normal? These vehicles, such as the venerable Toyota Prius, are great for commuters because they let you lower your fuel costs and help the environment as you make your way to work, school, or wherever you’re going. A lot of drivers in Morton ask us, however, “How long do hybrid car batteries last?” Sam Leman Toyota Bloomington is ready to answer this question for you. The legally required hybrid or electric warranty is eight years or 100,000 miles on the battery components, but your battery might last longer than that. We’ve got the full story ahead.



Expected Hybrid Car Battery Lifespan

Great news for those who want to buy a hybrid: hybrid vehicle manufacturers in the United States are legally required to provide a warranty on high-voltage hybrid battery packs for at least eight years or up to 100,000 miles. Not only that, auto manufacturers are also required to transfer the balance of any hybrid battery warranty to a new owner. That being said, these battery packs can still fail, and in our next segment, we’ll tell you what you can do to extend the life of your hybrid.

Causes of Hybrid Car Battery Life Reduction or Failure

There are multiple reasons why a hybrid car battery might not last as long as you’d think. Individual cells or modules can fail in the battery, most commonly due to:

  • Poor electrical connections between cells or battery modules
  • Auto manufacturing defects in battery cells
  • Extreme high or low battery temperatures
  • Manufacturing differences between cells
  • Mechanical damage to the battery during routine maintenance or service
  • Improper serving procedures, which is why you should have your hybrid vehicle serviced by the certified Hyundai service technicians on the Sam Leman Toyota Bloomington service team

If a Hybrid Battery Dies, Can You Still Drive the Car?

We sometimes get asked, “If a hybrid battery dies, can you still drive the car?” The answer to this depends on which battery dies in your Springfield vehicle. There are two batteries to contend with, the hybrid battery and a smaller battery for your electronics. If the smaller battery dies, you can still drive but without some of your electronics. If the main hybrid car battery is dead, don’t drive the vehicle. Schedule service with us today.
