2014 Prius @ 115k miles Hybrid Battery Health

Looks reasonable to me You don't complain about the car running poorly or doing anything inadvertently so everything should be good You should be getting between 37 and 51 miles to the gallon anything in that range is acceptable mileage depending upon what the car is doing like pulling the trailer or carrying for bicycles on a bike rack etc Good luck.

 

That P3000 error code is the first sign of a bad cell/module. If you keep a close eye on "Voltage Diff" number you'll be able to know when that error code is gonna come back. Basically anything up to 0.3v or 0.4v is manageable, but once it goes up higher than that on high amp loads it'll turn the dash lights on again. And you can keep driving and clearing those codes as long as you want as long as pack doesn't over heat. But in coming months or years you'll have to decide on a rebuilt pack, a brand new OEM pack, or an upgrade to the safest most advanced Lithium pack that you can learn more about via my affiliate link: https://projectlithium.com/?ref=9qLPw

 

Just did the Dr. Prius test myself. 2015 3rd Gen with 180k miles. No codes, 80% on life expectancy test. I think this should get me through a few more years anyway. I drive it a lot, so it gets cycled daily..
