If you’re considering a hybrid vehicle for your Smyrna drives, you might be wondering, “How long do hybrid car batteries last?” Or, perhaps you’re wondering, “If a hybrid battery dies, can you still drive the car?” Don’t fret! Marietta Toyota has all the information you need to know about hybrid car battery life below!

Hybrid Car Battery Life

Atlanta shoppers will be pleased to know that hybrid vehicle manufacturers in the United States are legally obligated to provide a warranty on high-voltage hybrid battery packs for a minimum of eight years or up to 100,000 miles. Additionally, U.S. auto manufacturers are legally required to transfer the balance of any hybrid battery warranty to a new owner.

It’s important to understand that high-voltage battery packs on hybrid vehicles can fail. Luckily, there are several steps you can take to extend your hybrid car battery life.

What Causes Hybrid Car Battery Life Reduction or Failure?

Individual cells or modules can fail in a hybrid car’s battery. There are several different ways this can happen, and the most common causes include: 

  • Auto manufacturing defects in battery cells
  • Poor electrical connections between cells or battery modules
  • Manufacturing differences between cells
  • Extreme high or low battery temperatures 
  • Mechanical damage to the battery during routine maintenance or service
  • Improper serving procedures

With the above points in mind, it’s essential that you have your hybrid vehicle serviced by the certified Toyota service technicians. By doing so, you’ll be able to make the most of your hybrid car battery life. 

Protecting Your Hybrid Vehicle’s Battery Pack

While we don’t recommend that you work on your own hybrid battery pack due to potential safety hazards, there is one significant step you can take to keep your hybrid vehicle’s battery pack in good condition that doesn’t involve working on it yourself. 

Pay Attention to Warning Lights

The hybrid battery monitoring system includes warning indicators and trouble codes that will display on your vehicle’s dashboard if any issues, malfunctions, failures, or defects are detected in the battery pack and its related systems. Examples of possible issues include: 

  • Abnormal battery temperatures potentially caused by problems with the dedicated computer-controlled battery cooling system
  • Abnormally high or low rates of charging
  • Imbalances between battery cells or battery modules. The failure of a single battery cell can potentially degrade the performance of the entire battery pack.

What Happens if a Hybrid Battery Dies?

One of the most commonly asked questions by Kennesaw shoppers is, “If a hybrid battery dies, can you still drive the car?” Given the fact that a majority of hybrid cars have two batteries, the answer depends on which battery died. If the smaller battery that operates your vehicle’s electronics dies, you will still be able to drive it. On the other hand, if the main hybrid car battery dies, you’ll need to schedule an appointment with your local Marietta Toyota service center immediately. Never attempt to drive your vehicle if your hybrid battery is dead.
