    Hey All,

    Just curious, what's everyones estimated battery capacity? For reference, I have a 2016 Prius with 132k miles and after running Dr. Prius's app it shows 65%. Back in July of 2020 it showed at 80% so looks like its currently degrading at ~5% per year.I'm also averaging around 45mpg which is really low and I can't really say I have a heavy foot either. I was averaging 55mpg back in 2020 but it dropped drastically. Changed out the spark plugs and did all the normal maintenance so not sure what else it could be.

    Mine was 265k on the original lithium and still going strong. I haven't checked the capacity on Dr. Prius but I'm getting 62 mpg in town and country roads (55 mph). Care Care Nut reviews a 2019 Prime (with Lithium) with 341 original miles on the battery pack.

    Nice! That's glad to hear... would love to be able to have mine hit the 250k mark... have you done anything special regarding maintenance other than the normal things?

    Nothing other than a head gasket replacement just recently. During this job, I replaced the water pump, thermostat, spark plugs, coolant and bypassed the exhaust heat exchanger. Also replaced the passenger side engine mount due to a buzzy engine vibration. Keep up with synthetic oil changes every 5k miles, coolant flushes every 30-50k, keep the hybrid battery fan intake filter clean, drive the car gently and you'll see many more miles. I would also bypass the exhaust heat exchanger for those of you who are not eligible for warranty replacement ( https://priuschat.com/threads/gen-4-coolant-leak.229705/ ).
