That's true but this person asked for differences between Wall Connectors and Mobile Chargers and I explained it, that’s all. The alternative is having a 40A circuit breaker and multiple Wall Chargers using power sharing at 32A which could use cheaper conductor wiring if you own multiple Tesla...

I believe the latest and greatest Wall Connector allows you to build a 60A circuit which could charge your Tesla car to the maximum of 48A continously (80% of 60A) while the maximum current of Tesla Mobile Charger is 32A or 40A circuit breaker. Plus you can control the Wall Connector via WiFi...

I see too often in many posts not saying whether the cables installed by electricians are made of copper or aluminum. This is pretty important to know. I know copper wires have higher current capacity than aluminum wires using SAME AWG wires. I believe generally speaking in typical residential...

Must be a nightmare for Tesla software engineers to maintain support for older Tesla models without affecting new models and vice versa. Peter

Are you saying because you have an older Tesla model, there are no more software updates maybe because your car is no longer compatible with latest Tesla software updates? Peter

I did the same thing. No permit necessary.

I think I'm beginning to get the picture. Thanks to all giving good explanations about this subject. Peter

So in layman's term, definition of preconditioning is basically heating the cabin area to warm up the battery pack underneath? I didn't think heating the cabin area was enough to warm up the battery quickly enough because I would expect good enough insulation between battery pack and cabin area...

I started the thread to learn how to be prepared to replace 12V battery for my 2020 M3. Currently, the voltage is about 14.8V. I don't yet need a new 12V battery. I have 10 months left of warranty. I hope it fails a month before the warranty expires to get a free 12V battery from Tesla. :cool...

I was only referring to preconditioning the batteries, not necessarily warming up the cabin area. It doesn't take long to warm up the cabin area after entering inside the car. Peter

Oh okay. I just found out we have a local Advance Auto store as well. Thanks, Peter

I looked at Advance Auto web site and you have to return your old battery or you'll be charged for the core. Do you have to pay shipping for returning old batteries? Peter

I wonder if the charger in newer Tesla using Lithium is different than older Tesla using lead acid batteries? If all they did was software upgrade and not change the charger, I wonder if the same can be done for older Tesla to replace lead acid with Lithium batteries using software upgrade? Peter

Thats great news. I see one at O'Reilly web site with vent hole. It's pricey at $240. https://www.oreillyauto.com/detail/c/platinum/super-start-platinum-battery-group-size-51r/ssbq/51rplt/v/a/149433/automotive-car-2020-tesla-3?q=51R+battery&pos=0 This is AGM battery which may or may not work...

I didn't realized 51R batteries are found in some popular small cars like Honda. Looking at my Tesla 12V battery looks tiny compared to the large battery in my Nissan Murano. Still it does not look easy to find 51R batteries with vent holes outside of Tesla. If my local Tesla SC doesn't have...

Why did Tesla make it difficult to use non standard battery? For ICE cars, it's so easy to find them, why can't Tesla do the same? Now, late Tesla cars use 12V Lithium batteries, I bet it's even harder and much more expensive to find them in local auto stores. Peter

That makes sense. Even though over night outside temperature can fall down to 20F, my garage temperature is never below freezing. Thanks, Peter

I've been reading about preconditioning and it's usually for people who goes to work regularly or plan for long trips. I'm retired and I drive at different times of the day or don't drive at all, so what's the best way to precondition to maximize battery life? I live in Reno, NV and winter...

Replaced 2013 MBZ 350SLK with 2020 M3 SR+. I find M3 more fun to drive. MBZ was a very difficult car to work on. For example, spark plugs were nearly impossible to access or replace.

My SC never complained about my display device when they were diagnosing issues with my PCS over heating, it turned out to be air in the coolant system that didn’t cool the PCS anymore. The SC simply purged the air from coolant system and problem was solved. The SC was actually impressed with my...

Can you change the "UI" to "UI2" and see if the clock remains at 12 hour format? You need to set time zone to GMT - 8. Are you tall? Can you lower the steering wheel? I'm 5' 8" and can see the display clearly. Peter

I see 3 different languages for this display device. I think there are 2 different Chinese dialects or one Chinese and one Korean plus English languages and that’s it. Peter

Thank you for pointing this out about vent hose and I was wondering about it. So I guess this battery is not recommended even though Duracell makes excellent car batteries. I have Duracell battery in my 2006 Nissan Murano and it has been wonderful. Peter

@Shorey1, why haven't you send me the firmware update that Tesery sent you? If you're not comfortable sending the firmware update publicly, please send it to me via Private Message (PM). Thanks, Peter

Bump. If you have a firmware update that works with 12 hour clock format and using "UI2" interface, please tell us the firmware version number so I can ask Hansshow to send me the same version number. @Storey1, why haven't you send me the firmware update that Tesery sent you? Thanks, Peter

Mine (very early 2020) originally came with 12V lead acid battery. I've been reading that replacing 12V lead acid batteries with 12V lithium can be problematic because it can confuse Tesla computer thinking the new 12V lithium need replacement even though there's nothing wrong with it which is...

I could but why can't they sell me the battery and let me install at my convenience? Wouldn't it be cheaper since I'm doing the labor myself? Peter

https://www.batteriesplus.com/productdetails/SLI51RM?utm_source=criteo&utm_medium=display&utm_campaign=similar I really like Duracell car batteries. I'm not interested in lithium based 12V batteries, just a simple replacement 12V lead acid battery since it seems difficult if not impossible to...

This is regarding to a minor issue using 12 hour clock format. If you have 12 hour clock format working using "UI" option set to "UI1", what about setting to "UI2"? If my "UI" option is set to "UI2", the clock format is always stuck in 24 hour clock format (13:XX instead of 01:XX) even if the...

Personally, I find Hansshow display device night mode brightness reasonably fine and Tesla screen night mode too dark using auto brightness. Peter

When the display device THEME option is set to AUTO, I believe the display device uses Tesla’s computer data to switch between day and night mode. Peter

@Shorey1, it's strange that Teresy doesn't post firmware updates at their web site. Peter

@Shorey1, can you please post the firmware here? I'd like to try it. Thanks, Peter

Looks cool. I've never order anything from Aliexpress and I'm skeptical of them. I know others like them. Peter

The problem with my TPMS is they measure 3 PSI less than several of my high quality digital tire pressure guages. So I think I would rely on tire pressure guage more than Tesla TMPS. YMMV. Peter

You're suppose to pump the tires to 42 PSI first thing in the morning because you're supposed to pump the tires to the recommended tire pressure when the temperature is at the coldest. When the tires warm up, it's okay for the tire pressure to be higher than recommended. Peter

The firmware posted at Hansshow web site works for me. You need to set CAN option to 2. The Plaid animation firmware contains 12 hour clock format fix. You need to install headlights status indicators firmware first and then the Plaid animation firmware and then set CAN option to 2. See post#...

I don't know because my car is not wired for heated steering wheel. https://www.hautopart.com/collections/tesla-model-3-y-x-s-yoke-steering-wheel/products/model-3-y-full-carbon-fiber-steering-wheel According to the above link, you can include heated steering wheel option. I don't know how well...

Or get carbon fiber steering like mine from Hansshow. It will never wear out. Very easy to install.

Must be Tesla haters. Peter

Ah, thanks. Peter

Anyone seen this annotated icon in Tesla app as shown below? This happened when batteries were charging. Thanks, Peter

It's small enough not to block airflow from vents. Depending on skill level, 30 to 60 minutes. If I had to do it all over again, probably 15 minutes. If you're car has AMD Ryzen CPU, it's much easier to install. This CPU is in late model, either 2021 or 2022 or later, not sure which year. Peter

The one with Plaid animation has 12 hour clock format fix. The other has headlights status indicators fix (CAN option must be set to 2). Peter

So do I. Hansshow shows two different firmware updates at their web site and I'm using a combination of both. See post #83 of this thread. Perer

I think Chinese engineers are excellent but seems to be terrible organizing firmware version numbers. It looks like like your version numbers are slightly ahead of mine. Mine still works great. Peter

Once you have a good understanding of reading three posts, I would concentrate on post# 83. Peter

It looks like your firmware version is a little bit behind. See posts #74, #83 and #93 of this thread. If you feel intimidated, let me know the details of what you're not understanding. Please re-read the three posts repeatedly until you really understand it. Peter

Can you take a picture of the settings so I can see the version number of the firmware installed? This is mine: Try set CAN option to "2". If that doesn't help, I can show you how to install appropriate firmware. For securing the clips at steering wheel column, you really have to compress...

I have this carbon fiber steering wheel. Much better and cheaper than Tesla stock steering wheels. The grip is really nice and has sports car feel. Very easy to install...
