Key Tesla battery stats at a glance
Model 3/Y Long Range degradation: Tesla has reported about 15% average capacity loss after 200,000 miles (≈ 85% retained).
Model S/X degradation: Tesla has reported about 12% average capacity loss after 200,000 miles (≈ 88% retained).
Warranty retention floor: Tesla’s Battery & Drive Unit warranty includes minimum 70% retention over the warranty period (coverage is 8 years, with mileage limits depending on model/trim).
V4 Supercharging (North America): Tesla states V4 can deliver up to 250 kW for Model S/3/X/Y and up to 325 kW for Cybertruck (at V4 Superchargers).
Energy storage deployed: Tesla reported 46.7 GWh deployed in 2025 (vs. 31.4 GWh in 2024).
Degradation is typically measured as capacity loss over time and mileage. Real-world range can also vary due to temperature, speed, tires, elevation, and software estimates, so treat these as benchmarks.

Charging network stats that shape battery usability
Battery performance matters more when paired with convenient charging access. Tesla reports annual Supercharger network expansion in its quarterly update materials.
Tesla also reported 77,682 Supercharger connectors at year-end 2025 (up from 65,495 at year-end 2024).
