Like @mstatkus above, I trickle charged with a lithium trickle charger until complete. It read about the same 14.5 volts as above. Installed (V4 not +) attached a bluetooth Lithium monitor. After 4-6 hours VCFront errors occurred. 2 "soft" errors meaning not active then a 3rd that remained...

Every battery I've installed goes into a constant charge for that 4-6 hours then starts winding down the charge. That's when I've had the Lithium errors. Fingers crossed.

14.41v is about the highest charge voltage I get with an AGM. You should start seeing any issues after 4-6 hours

Good data. There has been an update to the Tesla app to version 4.13.3 which corrected frequent (several times an hour) wake ups. If it threw a VCFront message at 13.3 volts then that thesis goes out the window. Now I am running a DiehardEV battery which is an AGM at charged voltage settles...

One question: What was the voltage while charging was working? When I tested a V4 (not V4+) the full battery voltage was at or lost to the charing output voltage so effectively not much charging taking place. After about 6 hours (when first installing 12 volt the system going into 12 volt...

This is a very helpful topic. Knowing the issue, being careful it still broke (probably from changing filter every 6 months instead of 2 years). Fortunately thanks to the diligence of all on here I already had the clutch plug and the pins on the shelf. Extracting the broken plug wasn't too...

Most tire shops that work on Tesla will have them. They can be had overnight on Amazon. The puck pin is to help with the jack at the proper jack point and can be used with floor jacks that have irregular lift pad. It can be jacked without a puck as long as the jack has a FLAT surface is...

Like you observe, it looks to me like Tesla is experimenting. One group with FSDBeta charging and one without. Here is a graph of charging taken today with 2022.20.18 (10.69.2.3). This profile has been fairly consistent with earlier profiles (looking at July) all with a peak around 14.3V...

I notice today the LithiumMoto.com Model 3/Y battery is unavailable until the battery builder finds a solution for "the problem Tesla created". Sounds like similar issues as followed on this thread.

I found it very helpful to install a battery monitor on my V4 to get the picture what the charging system was doing. Something like this: https://www.amazon.com/dp/B07NSVMY4S?psc=1&ref=ppx_yo2ov_dt_b_product_details It ism also possible right now the charging routine is different for the...

Not quite. Error messages will be generated. The procedure also requires turning power off, disconnecting main battery under rear seat and also removal of USB devices. Just removing terminals and swapping will work but procedure.

None of those issues were present in early 2020 and didn't start appearing for about a year later. So incompatibility issues were not known.

I looked and that’s correct. The way Tesla keeps tinkering with 12 volt charging profile that could be a negative game changer. I understand Ohmmu reasoning but since there is no way to predict Tesla future actions I would have to say no and I have been a strong advocate. Now it appears...

If coolant, did you run over anything? There have been cases where a fitting at the rear of the battery pack is broken off draining coolant from road debris. If so, a battery pack need replacing. Check insurance. A video by Electrified Garage on you rube shows how they repaired such a case...

What is the non charging voltage reading? Still 13.3V?

Keep posted if any VCFront messages. How long has it been since purchase?

I have noted with every battery I tried with a monitor module, the car goes into a charge cycle for about 4-6 hours so I wonder if that is why shipped with a low state of charge? What was the charge percentage after a few hours?

I see in the app store it says "This app is also used to perform battery resets and will be used to reprogram BMS settings in the future." I have a V4 sitting on the shelf and have requested the V4+ to test against then latest FSDBeta software. I also asked if they are collecting the data for...

Lots of questions with this app. "Enable Charge/Discharge"? Advanced? I like it. But any messages yet and if so, is it resettable using the app?

Make a service request and put in the part number. See if they can ship it to you.

What firmware version? I'm on FSDBeta 2022.20.17 waiting to do a swap when more data.

I have a Jeda Hub no issues with a 1TB SSD.

What brand of third party hub?

They may have tinkered with the charging profile again. With the latest FSDBeta, the charging profile changed. Before FSD update: After :

My 3 engages as soon as the car is stopped and the hold symbol appears. In settings pedals and steering do you have stopping mode set to "Hold"? Vehicle Hold When Model 3 is stopped, Vehicle Hold can continue to apply the brakes even after you remove your foot from the brake pedal. When...

As mentioned later firmwares should fix but also try a reboot, check for USB properly seated (sometimes removal and reinstall fixes). USB drives can fail. IF you have another try it. Don't forget to format the drive (the safety page now has a format button). Also in addition dash cam on auto...

Which software version?

Do you have in IOS Settings>Tesla> Calendar off or on? In the Tesla app itself settings Calendar Sync on or off? Thanks

Report it. Also, try signing our and back in.

Which software version are you running?

IOS 4.13.1 is now out. Don't know if this .1 is the fix yet.

IOS 4.13.1 just out. Don’t know if it’s a fix or not.

Try turning off calendar access in IOS>Tesla>Tesla app Calendars - Off AND Calendar sync in the Tesla app itself under settings. (per Tesla app folks- not sure if fishing or on to something).

One thing to try. Tesla app folks asked if I could turn off calendar sync in the Tesla App. In my case it was off BUT I also went into IOS Settings for the Tesla app and turned off Calendar access. Yesterday before those changes it cycled wake/sleep every 6 minutes today wake enters sleep...

IOS 4.13.0 out. All it says is bug fixes and improvements.

Tesla App just had an update IOS 4.13.0 All it says is bug fixes and improvements.

On a different thread I posted the charging graph measured with a monitor module both before IOS 4.12.x app and after. Each "wake" the charge voltage would go from resting to approx. 14.1 volts then drop back to rest in a few minutes. Then the cycle repeats.

Or anyone have the latest FSDBeta 2022.20.15 and an Ohmmu (any Versions)? Any messages or warnings?

Probably the thread I started. Bottom line, I'm seeing reports like this from all over the US and the EU. Open a service request, pick something else, and put in about the behavior with IOS app 4.12.x. They are working on it but the more data the better. If they offer a mobile visit pick that...

That is what Tesla had me do even though My only software (Watch for Tesla) had been removed. Didn't work. Then I removed the module and software that monitored the battery (and was the early warning about this). Problem persisted. Tesla got the logs and is still active on it today.

Which Tesla says is normal. So let's see if they find a solution.

For now leave everything as factory. Once this is done I will reinstall my AGM battery or possibly my Ohmmu. They want app in background running and bluetooth on. I did notice just now the app will say phone key connected when parked and outside with sentry off and unlocked. But my bluetooth...

FWIW Tesla is still actively looking into this. They have asked me to set the car up without charging overnight and leaving app running like normal in background with bluetooth active overnight.

None. I temporarily put it on the shelf for the Atlas only because I have (in another thread) constant wake and sleep behavior with the IOS app 4.12 and I wanted the charge cycles to go the the original battery not my new battery. I ran it for a month with a battery monitor and very smooth and...

I have that battery and they are SAE standard posts. The incorrect review was looking at a similar battery that had marine posts.

2/32 minimum for dry/wet. 4/32 minimum for snow. I start shopping at 5/32. Michelin Pilot Sport All Season 4's start at 10/32.

ANY 12 volt battery 51R with a minimum 33Ah rating (per the manual). Most 51R's exceed that. The factory AtlasBX is 45Ah. Advance Auto has a DiehardEV battery (it's an AGM battery) and is sized the same as the AtlasBX. I had a 51R AGM and the clamp was all the way down. Snug but not tight...
