What are the signs of a faulty hybrid car battery?

There are several tell-tale signs that the battery is on its way out, but nothing can replace getting the car diagnosed by a licensed professional using proper scan tools. But we understand you'll want to know what to look out for, so here are some symptoms to monitor:

  • Check Hybrid System warning is showing on the dashboard
  • Fuel consumption is increasing
  • Petrol engine is engaging earlier than usual, or on all the time (this means the battery is not providing power)
  • Faster cycling (charging and discharging of the battery) which you can see by monitoring if the battery reaches full bars more often
  • Fan is noisier than usual; the fan is used to deliver cooling air to the battery and it's engaged more if it's running hot (which is a sign of the battery not being able to hold charge like it used to)

Extremely happy with the level of service from John and Joel. These guys have a deep, technical knowledge of Hybrids and batteries, and they took the time and care to answer our questions. Joel even showed us the real-time ECU data during a test drive with his laptop once the new battery was installed. Very competitive on price and better warranty terms than Toyota. Highly recommended.

Late review but a massive thank you to John and his team for resurrecting my 2007 Prius. John knows batteries like Google! So knowledgeable and informative. Patient and accommodating. He managed to get me a refurbished battery pack considering he has such a long list of customers. No more triangle of death. Thank you John. The car is still running smoothly since the battery pack change 2 years ago!

10 months & 23,000 km since the hybrid battery in my 2006 Prius was replaced with a reconditioned one. The unit & the car have functioned perfectly since. I found John most interesting & helpful answering all my questions (& speaking to my inner-geek about how the hybrid system works & functions [cells, voltages, tolerances, etc] before & during the repair process which took about 2 hours.
