16V lithium low-voltage battery — not the drive pack, not a 12V upgrade

This is the small auxiliary battery under the frunk that keeps the computers, locks, and safety systems alive. OEM part 1598486-00-F (silver-case 16V NMC). It only fits cars that already run Tesla’s 16V lithium architecture. Year alone is not enough.

Do not install this in a 12V lead-acid car

Connectors, charging logic, and voltage are different. A mismatch can leave the car unable to wake. Professional installation is required — follow Tesla’s low-voltage isolation procedure. This is not a jump-in “plug-and-play” accessory.

Will this fit?

Check the car, then the battery label. US, EU, and China use the same 1598486 family — there is no separate regional battery. Highland / Juniper / HW4 cars may use a different lithium pack with a black case.

1

Check the screen. Controls → Software → Additional Vehicle Information → Low Voltage Battery Type. You need Lithium-ion. If it says Lead-Acid, stop — this battery will not fit.

2

Read the label in the frunk. The pack sits under the front trunk access panel. You want a silver case stamped 1598486-00-D, 1598486-00-F, or 1598486-00-G.

3

Reject the lookalikes. A black-case pack numbered 1875662 is LFP (common on Highland and some HW4 Model Y) — different pins and communication. A traditional 12V lead-acid pack is 1129182. Neither uses this listing. Photo of the label + VIN to if unsure.

Highland, Juniper, or HW4

2024+ Model 3 Highland, 2025+ Model Y Juniper, and some HW4 Model Y cars may have either a silver 1598486 or a black 1875662. Do not order by model year. Send the label photo before you buy.

12V cars and black LFP packs

  • Screen says Lead-Acid

Key features

OEM number 1598486-00-F

Direct replacement for the silver-case 16V pack Tesla fitted as 1598486-00-D / F. Match the stamp on your current battery before you install it.

Keeps the low-voltage system alive

Powers computers, locks, windows, and safety modules while the high-voltage pack is asleep. A weak LV battery is a common reason the car will not wake or shows “schedule service.”

Not a 12V lead-acid swap

16V lithium cars use a different connector and charging strategy. This pack is not an upgrade path for early Model 3 / Y or pre-refresh S / X.

Install with the service procedure

Isolate low-voltage power as Tesla specifies, then fit the pack in the frunk location. Incorrect reconnection can set faults. Professional install is strongly recommended.

Frequently asked questions

Can I put this in a 12V Tesla?

Details
No. If Additional Vehicle Information shows Lead-Acid, or the frunk pack is 1129182, this 16V battery will not fit and must not be installed.

My label says 1598486-00-D or 00-G. Will F work?

Details
D and F are the same silver 1598486 family; this listing is revision F and is the usual replacement for D. G is the later silver revision of the same family. If your label is G, send a photo of the full label to confirm before ordering. Black-case 1875662 is not this family.

I have a 2021 Model 3 / Y. Is that enough?

Details
No. Tesla switched from 12V lead-acid to 16V lithium mid-production (about late 2021, factory-dependent). Use the software screen and the battery label. Do not order by calendar year alone.

Highland, Juniper, or Hardware 4 — can I buy it?

Details
Only if the pack in the car is silver 1598486. Many of those cars use a black LFP pack 1875662 with a different connector. Photograph the label first.

Is this the big battery that drives the motors?

Details
No. This is the small low-voltage auxiliary battery. The high-voltage traction pack is a different part and is not sold here.

How do I know the LV battery is failing?

Details
“Schedule Service to Replace Low Voltage Battery,” restraint or electrical alerts, doors/windows acting up, or the car not waking. A fully dead LV battery may prevent the car from unlocking — use Tesla’s jump-start points; do not treat it like a conventional 12V starter battery.

Is installation DIY?

Details
We recommend a shop that follows Tesla’s low-voltage isolation steps. Incorrect disconnection can throw faults or damage controllers. Contact us before removing a suspected defective unit if you need after-sales help.

Can you ship this worldwide?

Details
This is a lithium-ion battery (~99Wh). Some countries restrict air shipment. If your destination cannot accept lithium by air, we will ship by an allowed method or contact you before dispatch.
