Model Y 12v Replacement Cost
The new version has just made its debut in the market. So the expected cost is not revealed yet. But the older lead-acid variant follows a similar nature.
It also has unstable costing that is based on different working areas. But the average pricing for the replacement remains between $100 to $200. Additional parts and the labour costing are the actual pricing.
Replace 12v Lead Acid Battery With Lithium 12v In Model 3
When an EV is off, the 12V load is much higher due to the advanced computer systems that are constantly running to maintain the high-voltage battery pack, keep the vehicle connected via remote access features, maintain charging and BMS communications, etc. It can put up to 50 Watts of load on the 12V system when the vehicle is off. This cycle ends up draining the 12V pretty quickly and requires it to be recharged by the high-voltage battery pack regularly.
When turning on an EV, the 12V uses no additional load. While driving, the 12V battery is used for non-driving tasks , while the high-voltage battery pack focuses on the driving part, which extends the driving range. The 12V battery is subjected to relatively low discharge and recharge currents due to the separation of tasks.
**Tesla recommends you leave your car plugged in when not in use. This will further the life of both of your batteries.
The problem:
An EV needs a 12V battery that can handle a high number of cycles and low current requirements, and an ICE vehicle needs the exact opposite: a battery for high discharge and low cycle counts. So, while these lead-acid batteries are doing their job just fine in an ICE vehicle, what does a Tesla need?
The Solution: Lithium batteries
Lithium batteries are typically used for high-voltage battery packs, cell-phones, laptops, medical equipment, and cars where batteries are being cycled frequently, and longevity is important.

Tesla Flat 12v Battery
Each Tesla has 2 batteries, the large expensive battery pack with an 8 year warranty and a traditional 12v battery that runs the cars ancillary systems like any other car. While many people monitor the health of the main battery pack, the 12v battery can fail or run flat, especially if the car is left for a long period of time and the main battery has entered its low energy mode.
If the 12v battery is flat then it can feel pretty terminal for the car, the doors won’t unlock, the computers won’t fire up and more worrying the main car battery will not charge. Tesla charge the 12v battery from the main battery pack, but Tesla also take the view they must protect the main battery pack as much as possible and if it is running low may put the battery into a deep sleep/low energy mode. This minimises any drain on the battery preserving its life, but this equally prevents it topping up the 12v battery and effectively paralysing the car. The 12v battery can run flat within 24 hours once the main battery pack has stopped supporting it.
All is not lost however, and this guide talks you through how to get going again so long as the car is close to a charge port and you have access to a few tools and a the ability to provide a 12v jump start. The basic sequence is:
This is a matter of last resort and the main battery pack running to empty is not advisable.
Tesla Launches New Amd Chip And 12v Li
Tesla has introduced the new AMD Ryzen chip and 12v Li-ion battery in 2022 Model 3 Model Y vehicles.
Earlier this month, we reported on a bunch of new features and changes coming to the Tesla Model 3 and Model Y that leaked through a test program in Europe.
Amongst many things, the leak revealed that new Model 3 and Model Y vehicles coming to Europe, which are made in China, would come with the new AMD Ryzen chip that is powering the media computer in the new Model S and Model X and the Model Y Performance made in China. Also, the lead-acid 12v battery will change to a Li-ion battery system.
As we noted at the time, changes made to Tesla vehicles made in China often end up coming to Tesla vehicles made in the US soon after. Now we learn that Tesla has started production of the Model 3 and Model Y with those changes in the US:
The first Model 3 and Y vehicles with MCU3 are now being produced and delivered in North America!
Its the same for the Li-ion battery system to replace the old 12v system:
New Model 3 and Y vehicles also include the new 12v battery.

Charging The Main Battery
Once you have breathed some life back into the 12V battery the car should be able to power up its computers. Open the charge port and connect a charger. When the main battery is so low, the charge will take some time to get going with any speed. We suggest not using a supercharger as the charge time may be very long and may inconvenience others.Let the cars battery management system charge the car as needed. You should be able to remove the 12v battery charger once the main battery charging has commenced.
The 12v battery may still be at a fairly low level of charge however once the main battery pack has reached a sufficient level of charge it will charge the 12v battery. Unlike internal combustion engined cars, you should not need to go for a lengthy driuve to charge the 12v battery.

Gaining Access To The Battery
To gain access to the 12v battery you need entry to the car. Each car is slightly different and the details of the steps to gain access are include in the user and first responder manuals however we cover the basic steps here.
The battery is accessible in the frunk of the car and so to gain access tot he battery, you need to open the frunk. If course with a flat battery you can’t just open the frunk as normal and you have to follow the emergency frunk opening procedure. Each model has a slightly different process for access and these are detailed in the appropriate guides linked to above, however as a quick start guide:
- On early model S, you may find access through no more than removing the nose cone.
- Tesla are increasingly putting cables behind the towing eye cover. Remove the cover and see if there are two wires that can be pulled forward. Connect the 12v battery charger to these and it should energise the lock.
- If there are no cables behind the towing eye cover, then behind the front wheel arches there are emergency release cords than can be pulled on each side. This should pop the bonnet.

Common Tesla Model 3 12v Battery Issues And How To Solve Them
Even though all vehicles have a 12V auxiliary battery, batteries used in Teslas have a greater tendency of dying out early.
Model 3 owner jcanoe had very interesting insights on the subject matter:
The things that cause a 12V lead-acid battery to fail prematurely are load, heat, vibration and time. You can monitor the voltage of the 12V system from the 12V accessory port with a voltmeter or a USB adapter with a built in voltmeter .
At some point Tesla reprogrammed the charging routine for the 12V battery as they were probably overcharging the 12V batteries and causing the 12V batteries to fail. This change may have helped extend the life of the 12V battery.
As Tesla was continuously trying to fix the rapidly dying 12V battery issue, they were observed getting rid of it with the help of a software update as mentioned in the above comment, but it didnt turn out as expected.
But then Elon Musk, in an interview with Sandy Munro, confirmed that they have finally moved all Tesla models to a lithium-ion battery to nip this issue in the bud for forever.
Elon Musk said,
Were finally transitioning to a Li-ion 12-volt battery. It has way more capacity and the cycle life matches the main battery pack. We should have done that before, but its great that we are doing it now.
Though some minor glitches of Li-ion battery were claimed by some Tesla owners in Europe , causing it to die really soon just like lead-acid batteries and leaving the vehicle stranded and undrivable.
