    Good videos. This subject bit me in the butt. I left my Prius V sitting while I drove my other car. I would start it up again. Eventually I forgot how to operate some of it. I'd look for the parking brake and not seeing anything just assumed I was remembering one of the ICE cars I used to have. The big "P" button was like the button on the end of the stalk of my Tesla. So it wouldn't move. Even when I looked around the floor, with a powerful LED flashlight, all that stuff is black on black on black. and the parking brake (also black...) just looks like another bump. So I let it sit some more. The 12v battery died. I bought a new one. I still let it sit and that one died too. My mechanic friend said "I'll do you a favor" and took it to be charged. No one said, "This battery is 12.2 volts, it's dead." So this is an important subject. If I charged it, or used the Jump start setting on my charger, the screens would turn on, but as soon as I pressed on the brake to hit the Power button it blinked off. So I assumed I had some other problem....
    So troubleshooting a Prius without any chip reader etc... is a great topic. Now I'm wondering if the traction battery has problems, and what questions to ask the local shop (I'm not going anywhere near the dealer.) to make sure they know and do what you do. Two mechanics advised me to just drive it and see if it sorts itself out. Seems to drive like I remember (but compared with the Tesla.... Had I not bought the Tesla I'd still be happy with my Prius V. Except for one thing. It will get stuck in mud or on ice behind a minor bump easier than any car I've ever driven. (The Model Y? I once drove it into a snow bank to park it. Right up to the windows. No problem)

    Had problems with the 12v battery on a, 2016 gen 3 Auris Wagon couldn't listen to the radio for more than 5mins, with out having to put the car in Ready, as low 12v voltage warning came up on the dash.
    Upon removal of the Battery, I peeled off from the top, the information label and placed it onto the side. Looks like the original battery from New, never been touched.
    Upon removal of the clear plastic anti tamper covers. There are rubber removable covers. Using a flash lamp 🔦 looking into the cells there wasn't any fluid in any of the cells, they where wet and grey in colour.
    Using Distilled water. Each cell consumed over a cup full of Distilled water. Then using a basic battery charger it was charged overnight night.
    The next day using a Hydrometer, i wrote down the readings, all the cells had the same specific gravity but where about halfway on a warm battery.
    I had to top up using more Distilled water each day.
    Using a smart charger with pulse technology the battery was topped off with fluids over a few day's of constant charging.
    Finally a Hydrometer reading was taken, surprisingly all the cells where the same specific gravity for a fully charged battery.
    Upon driving the vehicle i have noticed an increase in MPG with the ICE not coming on as much as before. When stopped.
    Before refitting the 12v battery into the vehicle it was washed down and the rubber covers refitted. A drop off silicon sealant was used on top of each cover. Finally using a strip of Duck tape placed over the top to hold the 6 covers in place sealing off any Gassing, refitted the vent tube into the side of the battery.
    The above maintenance was done a couple of year's ago.
    Since then, I occasionally charge the 12VOLTS with a smart charger with a safe max charge voltage under the operating voltage of the DC to DC Converter.when visiting the parents and checking the fluid levels and Hydrometer readings on each cell. All is still good.

      Useful information, thanks for sharing your experience. 👍 I wonder how many of these AGM batteries have been replaced when the electrolyte was low. 🤔
