LFP Wins This Tesla Model 3 Battery Degradation Comparison
InsideEVs testing finds Tesla's LFP cells outlast NMC chemistry in long-term capacity retention.
A new comparison by InsideEVs puts Tesla's Model 3 battery chemistries head-to-head on degradation, with LFP cells showing stronger long-term capacity retention than the automaker's NMC batteries.
What Happened
InsideEVs conducted a comparative degradation test between two Model 3 variants—one equipped with lithium iron phosphate (LFP) cells and one using nickel manganese cobalt (NMC) chemistry. The testing tracked capacity loss over time and mileage accumulation to evaluate which battery type holds up better in real-world conditions.
Why It Matters
Battery longevity is a critical factor for Model 3 owners and prospective buyers weighing the standard-range LFP variant against the longer-range NMC options. Faster degradation means reduced range, lower resale value, and potentially earlier replacement needs—all costly outcomes for consumers. This comparison helps clarify real-world trade-offs between Tesla's two battery strategies.
The Bottom Line
The InsideEVs testing indicates that LFP chemistry in the Model 3 shows superior long-term capacity retention compared to NMC cells, offering buyers concerned with longevity a clearer picture of what to expect from each variant.
