Tesla battery types: NCA, LFP, 4680 — which is more reliable
Guide to Tesla battery types: NCA 18650, NCA 21700, LFP, 4680. Reliability ranking from the Belarusian community's experience.
Description
Tesla uses different cell types and their reliability varies significantly. Knowing the battery type is a key factor when buying a used Tesla.
Battery ranking based on chat experience
- NCA 18650 (pre-facelift Model 3/Y) — tolerable, but on the pre-facelift the contact "whiskers" fall off; on the facelift coolant can flood inside.
- NCA 21700 82 kWh (facelift Model 3/Y) — the most problematic, cell imbalance, degradation.
- LFP (Standard Range) — more stable and reliable, but lower capacity.
- 4680 (Giga Texas Model Y) — AVOID. Zero repairability, astronomical repair cost.
- Certificates on 2023+ cars can quietly die. You can find out the battery type by VIN spec.
