AUX18L Auxiliary and Start/Stop Battery, by East Penn

We used the Remy 12V Battery AUX18L

In the US it's important to know that you can use the: Energizer TX24HL AGM Motorcycle and ATV 12V Battery​ as a replacement for the 12 volt. It costs $105 at Amazon. Its been working flawlessly since November of 2023. It may be important to note that in my 2014 the entire car went dead and I had to watch a YouTube to find the emergency hood pull. I had bought the car from a dealer in 2017 so my original 12 volt was between 7 and 9 years old. Absolutely amazing.

I’d caution slightly. This battery seems to be a different physical size than the OEM, and the terminals look different as well. I like this one, because it is a one for one replacement: https://remybattery.com/start-stop-aux18l-auxiliary-battery.html

I worked with Ohmmu to ensure that its LFP battery would work well with an i3. The i3 DC-DC converter's output voltage is ideal for an LFP battery. The 0.5V higher resting voltage of Ohmmu's LFP isn't a problem with an i3's 12V electronics because 12V components are designed work well with the 14.0+ output voltage of the DC-DC converter. The higher resting voltage and the much more flat voltage vs. charge level curve of a LFP battery means that the risk of all of the spurious DTC's being stored when the OEM battery's voltage drops too low when it fails isn't as great with a LFP battery. My Ohmmu LFP battery has been in our former 2019 and current 2021 i3's for about a year without any problems.

If your car still has its original 12 volt battery, your problems may be caused by a 12 volt battery failure. They tend to fail within 4 or 5 years, and, when they do, the car becomes completely inoperable.

Vendors have taken a variety of approaches to the self-driving problem. Tesla's approach is to allow their "full self-driving" (FSD) system to be used in all ODDs as a Level 2 (hands/on, eyes/on) ADAS.[3] Waymo picked specific ODDs (city streets in Phoenix and San Francisco) for their Level 5 robotaxi service.[4] Mercedes Benz offers Level 3 service in Las Vegas in highway traffic jams at speeds up to 40 miles per hour (64 km/h).[5] Mobileye's SuperVision system offers hands-off/eyes-on driving on all road types at speeds up to 130 km/h (81 mph).[6] GM's hands-free Super Cruise operates on specific roads in specific conditions, stopping or returning control to the driver when ODD changes. In 2024 the company announced plans to expand road coverage from 400,000 miles to 750,000 miles (1,210,000 km).[7] Ford's BlueCruise hands-off system operates on 130,000 miles (210,000 km) of US divided highways.[8]

Disengagement

In 2017, Waymo reported 63 disengagements over 352,545 mi (567,366 km) of testing, an average distance of 5,596 mi (9,006 km) between disengagements, the highest (best) among companies reporting such figures. Waymo also logged more autonomous miles than other companies. Their 2017 rate of 0.18 disengagements per 1,000 mi (1,600 km) was an improvement over the 0.2 disengagements per 1,000 mi (1,600 km) in 2016, and 0.8 in 2015. In March 2017, Uber reported an average of 0.67 mi (1.08 km) per disengagement. In the final three months of 2017, Cruise (owned by GM) averaged 5,224 mi (8,407 km) per disengagement over 62,689 mi (100,888 km).[155]

BYD, a company Elon Musk once dismissed by laughing at their products during a 2011 Bloomberg interview, has overtaken Tesla to be the world’s top EV seller. BYD said on Thursday that sales of its battery-powered cars rose nearly 28% to 2.26 million units in 2025. Vehicle deliveries at Tesla dropped 8% year on year to 1.64 million vehicles delivered in 2025.

A place to discuss problems of car centric infrastructure or how it hurts us all. Let’s explore the bad world of Cars!

You should either put chains on the Rear, or on BOTH front and rear. This is something I learned when first driving a front-wheel drive car. If you put chains only on the front and then you put on the brakes your rear wheels will have little control and can easily cause you to spin around. Having chains on the rear wheels provides a safe stop, slowing the rear of your vehicle and allowing the front to stay pointing forward.

HENRY GRABAR: Parking is the largest single land use in many American cities. If we were designing society from scratch, would we have placed car storage on the pedestal that it now occupies?

You know, one of the things that immediately jumped off the page for me when I was reading your book is the fact that, by square footage, there is more housing for each car in this country than there is housing for each person. And on its face, I have to say that statement feels incredibly problematic, but is it?

GRABAR: I don't think it's that surprising when you start to think about it. I mean, there are more - we build more three-car garages in this country than we build one-bedroom apartments. Almost every jurisdiction in this country requires parking as a part of every single building type, whether you're building a school, an apartment building or an office or a restaurant, the law requires a certain number of parking spaces. So we have parking minimums in every jurisdiction in this country, whereas for housing, we often have maximums. We say, on this plot, you can only put one unit of housing. You can only put two units of housing. So the fact that we've ended up with a surplus of parking and a shortage of housing is no surprise. In fact, it's by design.
