How much does Tesla charge for an out-of-warranty Model S battery replacement?

Tesla Service Centers typically charge between $13,000 and $20,000+ for a remanufactured battery pack replacement on 2012-2016 Model S vehicles.

Can an older Model S 85 pack be repaired without complete replacement?

Yes. The Model S 85kWh pack is composed of 16 individual modules. Degradation is often concentrated in one or a few modules. When the degraded module is replaced with a well-matched unit and the pack is rebalanced, usable range and charging performance can usually be restored close to the pack’s original condition.

Tesla Model S Battery Replacement: Module-Level Rebuild vs. Full Pack Replacement

When an out-of-warranty Model S experiences sudden range degradation or a BMS lockout, Tesla Service quotes between $13,000 – $20,000 for a complete pack replacement. Independent EV battery laboratories can restore your original pack for $1,800 – $3,500 through targeted module replacement and precision cell balancing.

MODULE-LEVEL REBUILD

Brick-Level Diagnosis

Instead of discarding 15 perfectly healthy modules, only the single degraded module is isolated and replaced.

PRECISION BALANCING

<4mV Pack Balancing

All 96 series cell bricks are equalized to within 4 millivolts, preventing sudden voltage drop-offs below 20% SoC.

WARRANTY PROTECTION

12-Month Written Warranty

Independent EV laboratories provide comprehensive 12-month warranties on replaced modules and contactor assemblies.

Frequently Asked Questions: Model S Battery

Will the vehicle's full driving range return after repair?

Yes. Once all 96 cell groups are balanced to identical voltage thresholds, the BMS allows the car to safely utilize 100% of usable pack capacity without premature voltage sag cutoffs.

Why is buying a used salvage battery risky?

Salvage packs from wrecked cars often sit uncharged at 0% SoC for months. This causes irreversible lithium dendrite formation and cell degradation, leading to premature failure shortly after installation.
