OEM 16V Lithium-Ion Battery Part 1598486-00-F

Factory-spec low-voltage lithium-ion battery designed for compatible Tesla Model 3, Model Y, Model S, and Model X vehicles originally equipped with Tesla's 16V auxiliary electrical architecture.

OEM 1598486-00-F · 16V Li-ion · Direct replacement

OEM 16V Lithium-Ion Battery 1598486-00-F for Tesla Model 3 Y S X

🔋

Factory 16V Architecture

Designed specifically for Tesla vehicles built with the 16V lithium-ion low-voltage system rather than the earlier 12V lead-acid architecture.

🎯

OEM Part Number Match

Verified as part number 1598486-00-F and intended as a direct replacement for compatible vehicles currently using 1598486-00-D or 1598486-00-F.

⚡

Stable Low-Voltage Power

Supplies the vehicle's low-voltage computers, safety systems, access functions, and convenience electronics with the voltage architecture they were originally engineered to use.

Why This 16V Battery Stands Out

✅

Exact OEM reference

Part number 1598486-00-F allows fitment to be verified against the label on the battery already installed in the vehicle.

🪶

Lithium-ion low-voltage design

Tesla's 16V lithium-ion architecture provides higher energy density than traditional lead-acid auxiliary battery designs used in earlier vehicles.

🔄

Direct replacement application

Intended for vehicles that were originally engineered around this battery family, avoiding the need to redesign or convert the vehicle's low-voltage architecture.

🧠

Supports critical vehicle electronics

The low-voltage battery supports the electronics responsible for vehicle wake-up, access, control modules, safety functions, and many cabin systems.

🏷️

Label-based fitment verification

Checking the existing battery label before ordering provides a simple way to distinguish compatible 16V vehicles from incompatible 12V configurations.

Important: This Is Not a 12V-to-16V Upgrade

This battery should only be used in vehicles that left the factory with Tesla's 16V lithium-ion low-voltage system. It cannot be used to convert an earlier 12V vehicle to 16V. Always confirm the existing battery part number before ordering.

OEM Battery Construction

Verify Compatibility Before Ordering

Model 3

Compatible production range: 2021.10–2023.

Model Y

Compatible production range: 2021.10–2023.

Model S

Compatible production range: 2021.06–2023.

Model X

Compatible production range: 2021.06–2023.

Part Number Check Required

Production year alone is not enough to guarantee compatibility. Inspect the existing low-voltage battery label and confirm 1598486-00-D or 1598486-00-F before ordering.

Professional Installation Recommended

Battery System Tesla 16V low-voltage

Installation Professional recommended

Compatibility Check Existing battery label required

1. Confirm the Existing Battery

Verify the vehicle uses the 16V lithium-ion system and confirm the existing part number before beginning service.

2. Follow Tesla Power-Down Procedures

The vehicle must be safely de-energized according to the appropriate Tesla service procedure before disconnecting the low-voltage battery.

3. Replace & Verify

Install the replacement in the original battery position, reconnect the vehicle according to the correct service sequence, and verify that no low-voltage or system fault warnings remain.

Safety Notice

Battery service involves critical vehicle electrical systems. Incorrect disconnection or reconnection procedures can cause fault codes or vehicle damage. Professional installation is strongly recommended.
