    Serious 12v battery corrosion. 4,700 miles

    the pH of Pepsi is 2.5, very acid! Not basic to neutralize acid from the battery. Baking soda and water is what you want. It will evolve CO2 when neutralizing acid. then rinse off with plain water.

    Serious 12v battery corrosion. 4,700 miles

    See that thing sticking out to the right of "Part description 12 V battery" on the edge of the battery? THAT IS THE VENT! It pulls off the battery and there is a plug in the new battery that is removed and the vent is inserted. Failure of the seal at the negative post and/or plugged vent line...

    Serious 12v battery corrosion. 4,700 miles

    There is a reason for the corrosion, plugged vent or defective seal at the terminal post. This is not normal.

    Serious 12v battery corrosion. 4,700 miles

    I bet the vent hose is kinked or plugged so internal pressure is building up. Maybe the cap was not removed and hose even hooked up at the factory. Check the hose!

    12volt Battery Replacement - NAPA Auto Parts

    the new "12 volt" battery is really 15.5 volts. Hardware was changed to accomidate it along withthe BMS. According to the Model S owner’s manual, the new battery has a rating of 6.9 Ah and 15.5 volts.

    How urgent is "12V battery degraded" warning?

    There was supposed to be at some point new BMS for the lead acid battery. Time will tell if batteries stop failing at 2 to 3 years.

    Second Tesla Considerations

    Odds are the supercharger is on a much higher distribution line that are above trees.

    Greasing upper control ball

    Anyone know what type of grease was used in the upper control ball joint? Lithium base, calcium base, polyurea or ? I plan on injecting grease into the rubber boot with a hypodermic/zerk adapter and don't want to add an incompatible grease...

    Home on a hill - regenerative braking

    Set navigation to the nearest supercharger, it will precondition the battery for charging.

    one bulb of left headlight projecting purple light...why??

    White is made up of multiple LEDS each with a different color. One is burned out.

    Does this panel gap look normal on the front trunk?

    There is a plastic stop under each side of the frunk you can rotate to adjust height, it that is the issue.

    Changed cabin filters, can't get the panel back on

    They just need to swap ends and locate the screw at the bottom. Are current 3/Y still with the screw on top?

    "Proactive" 12v battery replacement - good idea or overkill?

    ALWAYS remove the negative terminal first and replace it last.

    12volt Battery Replacement - NAPA Auto Parts

    Only on refresh X and S and it is a 15.5 volt battery since Li and Pb cells do not have exactly the same voltage. Do not expect to slap in a Tesla "12" V Li battery in a car designed for 12 V lead acid. Any update to the Tesla BMS can result in Ohmuu batteries throwing error codes, it has...

    Several have reported that they got a warning and then it died soon after. Most get no warning.

    12volt Battery Replacement - NAPA Auto Parts

    One cent cheaper than the OEM battery at Tesla. Good luck with the Hydrogen gas and sulfuric acid corrosion. Doubt Tesla would honor any warranty work caused by corrosion and leakage.

    Texas-Built Model Y to Launch with 4680 Cells

    Will there be a price difference between 4680 Texas Ys and California 2170 Ys? There should be a performance improvement in both charging and acceleration and miles with the 4680s. What's the market value of die cast front, rear and structural battery pack? The last word is Texas is for...

    Model 3 12v battery dead

    Watch Ingenerix at 7:14 where he opens the new Li battery. Look at all the circuitry, the voltage in not 12, it is 16 volts fully charged!

    Model 3 12v battery dead

    In the parts catalog but given all the problems Ohmuu is having to keep from throwing errors, there is no way slapping in any old LI battery is going to work. Tesla BMS is expecting a lead acid resistance and voltage curve which is quite different for a Li battery.
  28. iwannam3

    Model 3 12v battery dead

    NO, they would require a very different BMS which is in the main battery pack to supply charging voltage which is very different than lead acid. I would think the BMS would need different hardware components, but maybe? they could do it with software magic?

    Salvage title model 3

    It was totaled. That means if you pay a shop to fix it, it will cost more than the vehicle is worth. The only way to come out ahead is to do the work yourself. Are you able to do the work yourself? Otherwise its a parts car.

    12volt Battery Replacement - NAPA Auto Parts

    A standard battery has vents for each shell otherwise they would pop off due to hydrogen gas generation. When you put a std battery on a charger you should remove the caps so the hydrogen doesn't accumulate. You can see it bubbling on the lead. When you add water to top off the battery , the...

    12volt Battery Replacement - NAPA Auto Parts

    Tesla does not want acid fumes and hydrogen in the frunk area. All standard lead acid batteries release them through the VENTED caps on the top of the battery. I watched a battery blow its caps off when a guy yanked the charger leads of a charging battery and the sparks ignited the hydrogen...

    12volt Battery Replacement - NAPA Auto Parts

    NOT AGM, it is a vented conventional battery. AGMs are SEALED, no vent, can be mounted upside down! Why does that keep coming up? There is so much misinformation on the 12 volt battery. AGM may give you errors like the $500 Ohmuu each time Tesla updates the BMS for the conventional battery...

    12volt Battery Replacement - NAPA Auto Parts

    Good thing Tesla replaced it, some my use it as the final solution. The Atlas battery will vent Hydrogen gas and sulfuric acid fumes in your frunk area. I assume you have seen corroded battery posts and rusted out battery supports? That happens under an ICE hood with all the air flow, imagine...

    Did the replacement battery have a vent hose fitting? How much did it cost?

    12V battery replacement: Tesla Li-ion

    In stock over the counter at my Serv center. No core required, no core charge. You would think they would have a core to promote recycling the Pb.

    3 years >100K miles Battery and Service Status for those curious how its holding up

    I was thinking about the 12 V vent. The vent and price prove it is not an AGM battery.

    How urgent is "12V battery degraded" warning?

    OMG! It is true! Here is a vendor selling a cable to hook to your BMW to your laptop with their purchased software and schedule an appointment for their tech to access your car when you have install your new battery! Says it saves a lot of money compared to having the dealer do it. I believe...

    How urgent is "12V battery degraded" warning?

    Battery charging voltage is based on temperature, if they are so clever to do something different based on the age, why do the batteries fail so quick? If I disconnect and reconnect the same battery does it think it is a new battery? Has anyone see a ranger "calibrate" something to the new...

    How urgent is "12V battery degraded" warning?

    Don't believe the "warning will let you know" Most failures are sudden and no warning.

    Petition for changes/improvements on Tesla vehicles on this TMC site?

    I wasn't looking to start another list of complaints, but to get some interest on TMC for a place to vote on already identified issues to help Tesla set priorities.

    Petition for changes/improvements on Tesla vehicles on this TMC site?

    Is there a "change.org" type forum on TMC where changes or improvements can be suggested and voted on? A TMC wish list? Help set Tesla priorities. If not can one be created? It seems the only way to point something out to Elon is Twitter. I am sure TMC has Tesla's attention and it would be...

    Tesla auto wipers is a real danger

    Try sporadic mists and light showers like in the PNW. No excuse not to have sensitivity adjustable by voice or slider.

    [Do] Wheel Spacers Void Warranty?

    I would think the wheel and the wheel bearing assembly might not be covered by warranty. Wasn't designed for the new load. Maybe even brake rotors etc. Anything affected by the modification is yours. Who knows, they could claim a drive motor failed due to the non-OEM equipment. Good luck...

    How urgent is "12V battery degraded" warning?

    This just in, looks like new update doesn't like non OEM battery again! Yesterday at 11:47 PM I'm starting to have constant 12v warnings with my ohmmu battery. It'll work fine for a few days after doing hard reset, then the warning pops up. Started after getting the 2021.40.x update. Anyone...
