    I posted on here yesterday about the hybrid check engine light on. With a basic code reader, i removed it car was ok. Came on again I reset it.
    I brought a rebuilt battery, it went bad in only... they game me another one.
    While being stumped all night. Thinking maybe inverter or something else and ordering a better scan tool, I remembered i got the Dr. Pruis app.
    I did test today to see if the battery was ok. Test is bad, 33.3% capacity left it says at the end of life, weak block 8.
    Before buying a rebuilt battery, I got some used cells on eBay and installed them. Was better. But later on, I treated myself to a rebuilt battery.
    My question is. I will put in pictures at the bottom.
    Can I last a few weeks like this?
    I can take out and battery apart. Should I just replace 2 cells in #8 block? Happy Thanksgiving, thanks for reading.
    you guys think i will get stuck..i can put cells in myself sunday..advice

    Have you found out why the check hybrid light is on, yet, or are you just assuming that because of the Dr Prius battery life report, that must be what the car wans to tell you about?

    You haven't included any screenshot where Dr Prius shows you trouble codes. I believe it is able to show some trouble codes. It can only show codes from a small fraction of the ECUs in the car, and it miscategorizes some, but it may well show you the codes that apply here.
