FAQ
What kind of 12V battery does Tesla use?
Tesla Model 3 and Model Y originally use a lead-acid 12V battery, specifically the AtlasBX / Hankook 85B24LS 12V 45Ah for Model 3. Recently Tesla introduced a 12.8V Lithium Iron Phosphate (LFP) battery option in newer models (2024 and later), which offers better longevity and efficiency.
How many amps is a Tesla 12V battery?
The Tesla 12V battery in Model 3 typically has a capacity of around 45Ah (amp-hours). The cold cranking amps (CCA) rating varies by battery model but is generally about 330-450 amps for starting power depending on specifications.
How long does a Tesla 12V battery last after warning?
After a 12V battery warning, Tesla recommends replacement soon as battery life is declining. Typically, a 12V battery might last a few weeks to a couple of months after warning, but continuing to operate risks vehicle shutdowns or system malfunctions.
Does Tesla come with a 12V battery?
Yes, all Tesla vehicles come equipped with an onboard 12V battery to power auxiliary systems, lights, and electronics separate from the high-voltage traction battery.
How To Replace Tesla 12V Battery?
Replacement involves locating the 12V battery (usually in the front trunk), disconnecting negative and positive terminals, removing the old battery, installing the new one (matching size and specs), and reconnecting terminals. Tesla recommends using OEM or compatible lithium replacements with proper reset procedures in the vehicle’s software.
What Is The Tesla 12V Battery Price?
Tesla 12V battery price ranges widely: OEM lead-acid replacements cost about $90 to $150, while aftermarket lithium 12V upgrades can run from $300 to $600 depending on the brand and features like Bluetooth or battery management systems.
Where To Buy Tesla 12V Battery?
Tesla 12V batteries can be purchased directly through Tesla Service Centers, authorized dealers, or aftermarket suppliers online. Lithium upgrade batteries such as from Ohmmu are popular aftermarket choices for Model 3 and Y.
What Is Tesla Model 3 12V Battery Size?
The Tesla Model 3 12V battery corresponds approximately to Group Size 51R or 85B24LS, with dimensions around 185mm x 116mm x 198mm and a 45Ah capacity.
What Is Tesla Model 3 12V Battery Price?
The typical replacement price for Tesla Model 3’s OEM 12V lead-acid battery from Tesla service is about $90 to $150. Lithium aftermarket replacements cost more, usually between $300 and $600.
How To Replace Tesla 12V Battery For Model Y?
Model Y 12V battery replacement steps are similar to Model 3: access the battery compartment, ensure vehicle safety mode, disconnect terminals, replace the battery, and perform the “learn new battery” function in the vehicle software. Lithium battery options require compatible BMS and app support.
What Is Tesla 12V Battery Replacement Cost For Model Y?
Tesla Model Y 12V replacement cost ranges from $90 to $150 for lead-acid OEM batteries via Tesla Service. Lithium upgrades cost higher, around $300-$600, depending on brand and features.
