How do I tell if a hybrid battery is bad?

I bought a used Toyota RAV4 Hybrid from a private seller, and at first, I had no problems. Now, I’ve been noticing poor fuel economy and I think the battery is to blame. How can I tell if my hybrid battery is going bad?

Don’t you just wish those batteries could last forever? The hybrid battery on a
Toyota RAV4 Hybrid
, typically lasts about eight to 10 years, depending on your model year. If you’re in that range, your battery is probably on its last leg.
To tell if a hybrid battery is on its way out, look for these symptoms:
  • The combustion engine kicks on more often than usual
  • Your fuel economy drops significantly
  • The hybrid engine makes strange noises
  • The battery loses its charge quickly
  • The battery is unable to hold a charge
If you notice any of these signs, take your car to the mechanic as soon as possible. The mechanic may find that only certain cells of the battery are damaged, which is an easier fix than replacing the entire battery. A replacement battery for a RAV4 Hybrid costs around $2,000 to $5,000, depending on whether you choose a new, used, or refurbished battery.
Whether you decide to replace the battery or get a new hybrid, it’s a perfect time to shop around for a new car insurance policy with the
