High Mileage Hybrid Vehicles (2020+)

Question

Hi all

Would a high mileage (over 100K miles) hybrid vehicle battery(yr: 2020+) be of concern of degrading a lot? What can you expect out of the life/condition of the hybrid battery? Curious to know if anyone who purchased a used hybrid would have that type of information by having pre-inspection purchase of some sort or dwelled into it. TIA!

Best regards,

Just

Well they certainly can degrade. I just shot a video yesterday with a hybrid laxis that had 140,000 and my test equipment showed it had 59% of the lifespan left. Any good mechanic has such tools. That's why you have to have them check out a hybrid before you buy it

@scottykilmer If one was looking for a mechanic to do a pre purchase test of a hybrid battery, what should we look/ask for?

I came across a web site that indicates that a "stress test" should be performed and that a Toyota or high-end Matco or Snap-on scan tool should be used. Is this basically accurate?

" Stress Testing

For this test you will need to find a repair shop that has a scan tool that can gather the live data from you hybrid battery. Special diagnostic tools like the “TechStream” for Toyota or Aftermarket scan tool like Matco or Snap-on will provide the data needed to perform the Stress Test.

Basically what happens during the test is first is to find a safe vacant back street to perform the stress test, once you are ready to start the test, the technician will need clear the Diagnostic Trouble Codes so the car is not in low propulsion mode or limp mode. The data from your hybrid battery is collected and recorded first. Then turn on live data collection and then accelerate the car at full throttle, up to 30 mph and then shifted into neutral prior to braking, so as to not let the regenerative brakes add energy back into the battery, coming to a complete stop. This is repeated five times in a row, stressing the capacity of the battery. Now with the data gathered from the live test, you will now know the true State of Health of your Hybrid Battery. Now you will know when it is time for your Hybrid Battery Reconditioning."
