This Tesla Model 3 Battery Chemistry Ages Better Than The Rest

• The CATL LFP pack retained 93.3% capacity after 62,000 miles, the best of four Model 3 batteries.
• The worst performer, a 52.4-kWh Panasonic pack equipping U.S.-built Model 3s, averaged 88.2% battery health.
• Carla’s findings echo earlier Voltest data showing stronger long-term retention from LFP packs.

There are many variations of the Tesla Model 3 with different battery packs that lose capacity at different rates. A large analysis from Carla in Sweden found a meaningful difference in battery degradation between four Model 3 pack variants after more than 100,000 kilometers, or around 62,000 miles.
