This 2023 Model 3 Has Tesla’s Durable Battery. It Still Degraded

Its LFP pack had 90% health at 26,000 miles. That’s not a disaster, but it’s worse than the chemistry’s reputation suggests.

Why this matters
Why now

The increased adoption of LFP batteries in EVs is leading to real-world data emerging, challenging some initial performance expectations.

Why it’s important

Battery degradation is a critical factor for EV adoption, resale value, and long-term sustainability, directly impacting consumer confidence and manufacturing strategies.

What changes

Optimism about LFP battery longevity may need to be moderated as real-world use cases show performance that is not always superior to other chemistries.

Winners
  • · Battery research and development
  • · Battery replacement services
Losers
  • · EV manufacturers relying solely on LFP durability for marketing
  • · Early LFP EV adopters expecting minimal degradation
Second-order effects
Direct

Increased focus on battery management systems and charging behaviors to mitigate degradation in LFP packs.

Second

Potential for slower consumer adoption of LFP-equipped EVs if degradation concerns become widespread.

Third

Accelerated investment in alternative battery chemistries or enhanced LFP formulations that promise superior longevity.
