    Tesla Model S vehicles rely on a dedicated 12V auxiliary battery to power essential low-voltage systems independently of the high-voltage drive battery. Without a healthy auxiliary battery, critical functions including door locks, lighting, heating, and the central touchscreen display may fail to operate correctly. This AGM U1 auxiliary battery is purpose-built to meet the specific demands of the Tesla Model S (2016-2019) 12V low-voltage electrical architecture. Constructed using Absorbent Glass Mat (AGM) technology, this battery delivers stable, consistent power delivery with superior resistance to deep cycling and vibration compared to conventional flooded lead-acid units. AGM construction eliminates free electrolyte, reduces gassing, and supports the sustained low-current draw typical of always-on vehicle management systems. This battery is engineered to fit the Tesla Model S auxiliary battery position directly. Dimensions are 197mm x- 131mm - 186mm (L x- W x- H) with a U01 case type, Terminal Type 1, Hold-Down B00, and Standard Polarity (0). It carries a rated capacity of 30Ah (C20) at 12V and weighs 12.1kg. Cross-reference: AGM U1-450LS. Start-stop compatibility is supported by the AGM technology; verify against the product label prior to fitment." No variants are currently available for this product. This battery is supplied with a 1-year warranty covering manufacturing defects under normal operating conditions. " . Tesla 12V auxiliary battery Tesla vehicles have a 12V battery to power essential low-voltage systems such as lights, door locks, heating and the touchscreen display. This setup is safer and ensures these systems remain operational even if the main battery is depleted.

Frequently Asked Questions

Q1- Which vehicles is this AGM U1 battery compatible with?
ANS- This battery is designed for the Tesla Model S produced between 2016 and 2019, where it serves as the 12V auxiliary battery powering low-voltage systems such as lighting, door locks, heating, and the touchscreen display.

Q2- What is the capacity and voltage of this battery?
ANS- This battery is rated at 12V with a capacity of 30Ah measured at the C20 rate.

Q3- What are the physical dimensions of this battery?
ANS- The battery measures 197mm in length, 131mm in width, and 186mm in height including the terminal. It has a U01 case type.

Q4- What is the terminal type and polarity configuration?
ANS- This battery uses Terminal Type 1 with Standard Polarity (configuration code 0) and a B00 hold-down specification.

Q5- Is this battery compatible with start-stop systems?
ANS- The AGM technology used in this battery supports start-stop functionality. However, you should verify compatibility against the label on the battery itself prior to installation.

Q6- Why does the Tesla Model S use a separate 12V auxiliary battery?
ANS- Tesla vehicles use a dedicated 12V auxiliary battery alongside the main high-voltage drive battery. This arrangement powers essential low-voltage systems such as lights, door locks, heating, and the touchscreen display independently, ensuring these systems remain operational even when the main battery is isolated.

Q7- What is the cross-reference number for this battery?
ANS- The cross-reference for this battery is AGM U1-450LS.

Q8- What does AGM technology mean and why does it matter for this application?
ANS- AGM stands for Absorbent Glass Mat. In this construction, the electrolyte is held within glass fibre matting rather than being free liquid, making the battery spill-proof and more resistant to vibration and deep discharge cycles. This is well suited to the continuous low-current demands of a Tesla auxiliary system.

Q9- What warranty is provided with this battery?
ANS- This battery is supplied with a 1-year warranty covering manufacturing defects under normal operating conditions.

Q10- How long will delivery take and what is the returns policy?
