OEM 16V Li-ion Battery (Part 1598486-00-F) for Model 3/ Y/ S/ X
OEM 16V Li-ion Battery (Part 1598486-00-F) for Model 3/ Y/ S/ X
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.
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
Part number 1598486-00-F allows fitment to be verified against the label on the battery already installed in the vehicle.
Tesla's 16V lithium-ion architecture provides higher energy density than traditional lead-acid auxiliary battery designs used in earlier vehicles.
Intended for vehicles that were originally engineered around this battery family, avoiding the need to redesign or convert the vehicle's low-voltage architecture.
The low-voltage battery supports the electronics responsible for vehicle wake-up, access, control modules, safety functions, and many cabin systems.
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.
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
Verify the vehicle uses the 16V lithium-ion system and confirm the existing part number before beginning service.
The vehicle must be safely de-energized according to the appropriate Tesla service procedure before disconnecting the low-voltage battery.
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.
Battery service involves critical vehicle electrical systems. Incorrect disconnection or reconnection procedures can cause fault codes or vehicle damage. Professional installation is strongly recommended.

Quick Answers
Can I use this to upgrade a Tesla with a 12V battery? +
No. This battery is only for vehicles factory-engineered around Tesla's 16V lithium-ion architecture. It cannot be used as a drop-in conversion for a 12V system.
How do I verify that it fits my Tesla? +
Inspect the label on your existing low-voltage battery. This replacement is intended for compatible vehicles using part number 1598486-00-D or 1598486-00-F.
What are common signs that the low-voltage battery may be failing? +
Possible signs include low-voltage battery service warnings, restraint-system alerts, unusual door or window behavior, or a vehicle message instructing you to schedule low-voltage battery replacement.
Is professional installation recommended? +
Yes. Correct Tesla power-down and reconnection procedures should be followed to avoid electrical faults or vehicle damage.
What are the battery's electrical specifications? +
The battery label identifies it as a 16V lithium-ion battery rated at 6.9Ah and 99Wh.
