Hybrid Battery Replacement

Overview

Believe it or not, the hybrid battery is actually just a bunch of smaller batteries hooked up back to back. It depends on the model, but your hybrid battery can be composed of anywhere from 20-40 of these little batteries, called “modules” by Toyota. When we replace your hybrid battery, we remove the old modules and put in brand new OEM Toyota modules. 

Pricing

Pricing depends on the model. Not just because of size, but some are just more complex and thus take more time to dismantle. 

So which models do we service? Pretty much any car that uses Toyota nickel metal hydride (NiMH) batteries. There’s the usual Toyota and Lexus models:

  • Toyota Prius C (2012-2018)  –   $2,300
  • Toyota Prius (2004-2015)  –  $2,900
  • Toyota Prius V (2012-2017)  –   $2,900
  • Toyota Avalon (2012-2019)  –   $3,400
  • Toyota Camry (2007-2018)  –   $3,400
  • Lexus CT200h  –  $2,900
  • Lexus ES300h (2013-2020)  –   $3,400
  • Lexus GS450h (2007-2015)  –  $3,900
You may be surprised to find that some non-Toyota cars also use Toyota NiMH batteries, such as:
  • Nissan Altima (2007-2011)  –   $3,400
  • Chevy Silverado (2008-2013)  –  $3,900
  • Chevy Tahoe (2008-2013)  –  $3,900
  • Dodge Durango/Aspen (2008-2013)  –  $3,900
  • Cadillac Escalade (2008-2013)  –  $3,900
 

How to tell that your hybrid battery is bad

The first symptoms of a bad hybrid battery are typically some combination of:

  • the gas engine suddenly staying on all the time
  •  a loud fan in the back of the car, also staying on all the time
  • The dashboard going nuts with a triangle somewhere staying, you guessed it, on all the time
  • on some models, an actual message saying something like “check hybrid system”
If all of these happen at once, it’s a telltale sign that the hybrid battery has gone bad. And if I didn’t own a scan tool, I think i’d be right in that diagnosis 99% of the time, maybe more. But really, at this point, the car should be scanned for confirmation. 
 
Bad hybrid batteries aren’t a binary thing though, good or bad. They often fail in a grey area. In many cases, you can trick the car into thinking the hybrid battery is good by disconnecting and reconnecting the 12V battery and car will just go right along with it. But I don’t recommend doing it. Not because the car will explode or anything, but it could eventually pop the top off of one of the modules and leave you stranded, which is what happened to the owner of the battery seen below.
