Guide to Hybrid Car Battery Replacement - Part 2

In part 1 of this series we covered how long a hybrid car battery can last and signs of battery problems.  Part 2 will talk about what you can do if your hybrid battery is having trouble.

Options for Replacing Your Hybrid Car Battery

When the bell tolls for your Prius battery, replacing it with a brand new battery is not the only option!  A certified hybrid repair specialist will be able to test your Prius car battery and recommend the best course of action for your particular circumstance.

  • Reconditioning – When the physical structure of the battery is fine but some of the modules have lost some of their capacity, reconditioning restores their performance.  By charging then discharging the battery modules in a certain sequence, performance is restored to poorly functioning modules.
  • Rebuilding – If there is damage to the physical structure of the battery, then those damaged components will need to be repaired or replaced.  Damage could happen as a result of an accident or if some part of the battery becomes corroded due to age, driving cycle, or other environmental factors.
  • Remanufacturing –  Though similar to reconditioning, remanufacturing goes a step further.  Once a battery has been tested and gone through the reconditioning process, some of the battery’s modules may continue to show they’re failing.  In this case the failing modules are removed from the battery and replaced with working, reconditioned modules from another source.
  • Replacing – This is exactly what it sounds like.  The entire old, malfunctioning battery is removed from the Prius and replaced with a brand-new battery.

What’s the Best Option for Your Prius?

Ah, that’s the million dollar question!  You don’t have to go to a dealer to get your Prius battery tested.  Look for a local hybrid repair shop that has the latest diagnostic equipment.  They’ll be able to gather crucial performance data.  Base your decisions on the data from a trained and experienced source.

Don’t Try This at Home!

If you’ve experienced signs of possible hybrid car battery issues, take these steps:

  • DO NOT attempt to diagnose and fix the problems yourself!  Unless you are trained and certified in the complex nature of hybrid electrical systems you run the risk of injuring yourself and damaging your car.
  • Check your warranty.  If you’re still within your warranty period, the easiest way to fix your battery problem is by using your warranty.
  • Take your Prius to a trusted certified technician for testing.  If your Prius warranty is no longer valid, find a certified hybrid technician.  They will perform the necessary tests and provide you with recommendations for moving forward.

The good news is that Prius batteries are not prone to failures or problems.  Both Consumer Reports and Green Car Reports say that battery failure is not the norm.  Priuses famously last for hundreds of thousands of miles.

Happy Driving!
