  1. Gokhan replied to the thread AGM battery for Gen 4/Gen 5 Prius/Prius Prime and observations on the 12-V charging system.

    No, the voltage never stays at 14.2+ V at idle unless it is doing aggressive charging, which has nothing to do with putting the car at...

  2. Gokhan liked Mr.Vanvandenburg's post in the thread AGM battery for Gen 4/Gen 5 Prius/Prius Prime and observations on the 12-V charging system.

    My 2020 Prime once again charged fully yesterday, and it wasn’t any 20 hours since the last time. It had been colder. Without the...

  3. Gokhan replied to the thread AGM battery for Gen 4/Gen 5 Prius/Prius Prime and observations on the 12-V charging system.

    The voltage at idle is 13.53 V, and the charging current is small as a result. I wouldn’t bother leaving the car at idle to charge the...

  4. Gokhan replied to the thread AGM battery for Gen 4/Gen 5 Prius/Prius Prime and observations on the 12-V charging system.

    So, after the once-in-every-20-driving-hours-full-charging event (it looks like once in every 40 driving hours in practice), the AGM...

  5. Gokhan replied to the thread Is the final "grunt" on stopping normal?.

    If you can hear any brake noise over the Prius pedestrian-warning sound, it is not good. And don’t try to fix your brakes by braking...

  6. Gokhan replied to the thread Is the final "grunt" on stopping normal?.

    It is not. My 2021 Prius Prime Limited brakes are always whisper-quiet, and I didn’t hear brake noises when I test-drove a Gen 5 Prius...

    The once-in-every-20-driving-hours-full-charging event took place tonight. The DC–DC-converter voltage stayed at about 14.25 V (reached...

    Yes I was pleasantly surprised that repair revived a motorcycle battery the was below 11V and I got about a year more out of it. I knew...

  9. Gokhan replied to the thread AGM battery for Gen 4/Gen 5 Prius/Prius Prime and observations on the 12-V charging system.

    Yes, the repair mode is different, and that’s in which it produces a higher voltage to reduce sulfation than in the mild desulfation...

  10. Gokhan liked kiwiscoot's post in the thread AGM battery for Gen 4/Gen 5 Prius/Prius Prime and observations on the 12-V charging system.

    Mine is a bit different to that one as it's only a 5 stage charger and only 6A . Mine does do the 15.5 or 15.7V charge (memory a bit...

    It goes up to 15.5 V according to the specs. https://m.media-amazon.com/images/I/C1+wjw4oqlL.pdf

  12. Gokhan replied to the thread 2024 Prius Prime dead battery.

    I don’t think there is a simple way. Interestingly, the Gen 5 new-car features manual mentions that when the 12-V-system load is high,...

  13. Gokhan liked Mr.Vanvandenburg's post in the thread 2024 Prius Prime dead battery.

    Do you think there is a way to change the programming of the 12 volt charging? It should always try to charge to 100%, like old cars do....

  14. Gokhan replied to the thread What brand tires do you have on your Gen5?.

    In my 2021 Prius Prime Limited, if set the DRCC to 57 mph on the freeway, I get 75–80 mpg on the display for the trip with no...
