    Minor update:
    -VW vent grommet wasn’t useful
    -2012-2017 Prius C vent tube has two different part numbers and the parts are indeed different. One has the elbow that looks like every other elbow I’ve seen. The other has an elbow with a larger end that fits the Duralast battery. After some splicing and dicing, my temporary battery is now vented.

    Long-term update:
    The aftermarket 2012-2017 12V battery is still installed in my 2018 Prius C. We've only used it for shopping and around town, so probably 500mi since early March. It works, but I wouldn't take it far. I finally have a correct Toyota battery on order, but with no ETA. They are supposedly being produced by Interstate and now cost ~$250 vs. $450 for the previous (OEM) Yuasa.

    The new part # is: 00544-H3LN0-TS

    FYI.

    We just bought a nice 2019 certified used Honda Fit so that we now have a reliable vehicle in case of emergency etc. and that we feel comfortable taking anywhere. We were planning to buy a second car at some point. If the new battery doesn't arrive by soon after the new year, we're going to unload the C and probably get another Fit. Simple, reliable and I can buy a replacement battery in any number of places (including OEM at the dealer) within 5mi of my home. Right now if I wanted. I can't say that for my Toyota...

    I know that the supply shortage is an ongoing problem, so there may be nobody to really blame for battery availability. I just have to wonder why the 2018+ Prius C has a battery with a form factor that is not found in any other car sold in North America. Bad design choice. We feel abandoned and will never buy another Toyota.

    Anyway...

    Before I put the OEM battery back, I'll take/post photos of the 2012-2017 battery cage and venting system that I cobbled together.

    there have been a lot of problems replacing prius 12 volts over the years. they are always a proprietary size, limiting aftermarket options andoften scarce even at dealers.

    definitely one of those issues toyota turns a blind eye to

    That’s unfortunate. If I had done sufficient homework, I wouldn’t have bought the car. I’ve written to Toyota and will cc: NHTSA asking for a recall to retrofit these cars to accept the older model battery for which there are several aftermarket options. I’m sure it will go absolutely nowhere.

    Edit: Just filed my complaint with NHTSA. I’m not sure it qualifies as a safety recall, but we’ll see if they respond. My complaint # if you’d like to follow up: 11442218

    I am sure that it is NOT.
    And you are doing all of us a dis-service by cluttering up their system with your personal gripe.

    That’s a bit of a stretch.

    One might argue that’s a safety issue if I have to engineer and build a cage to accommodate a different battery in order to keep the car functional to buy my family groceries.

    It’s not personal. It’s strictly business.

    Carry on…

    No it isn't.....on either count.
    As long as a "plug and play" battery is available anywhere, they have met their obligation.
    Your unwillingness to USE the right battery is 100% personal.
    And if there is any safety concern, YOU are creating it.

    Sigh…

    the correct battery is not and has not been available since I starting looking (everywhere) in early March. Anywhere. At any price. There is no plug and play. Read the thread.

    Here is the NHTSA complaint:
    Check for Recalls: Vehicle, Car Seat, Tire, Equipment | NHTSA

    Curiously, I’m expecting a call from Toyota ‘Brand Engagement’ today. I’m not sure what they want. All I want is to spend $250 on the correct battery, which doesn’t exist. Stay tuned.

    So.....please refresh my memory with what makes the batteries that ARE available "not correct"?

    Taken at face value, I would be pissed too........and would like not to have this problem when my '17 C and my daughters '18 C needs a new 12 V battery.

    But having said that, stories like this almost ALWAYS are missing a critical detail.......like "Oh yes, THAT battery will work but I don't like how it fits." or something similar. After all, some people are using wheelchair and lawn mower batteries.

    Please keep us updated.

    I’ll have the H3 battery tomorrow. I removed my jury-rigged battery and restored the brackets etc. back to original, so tomorrow it will indeed be plug and play. ;)

    Battery installed and everything seems fine. Except that the release cable failed when I went to check under the hood. Something else to sort out.
