Why Your Used Tesla Should Have LFP Batteries
"A used Tesla Model 3 is easily one of the best electric cars you can buyand probably one of the best cars, period. Tesla's original mainstream EV is abundant on the secondhand market, has solid range and charging specs, packs class-leading software and can be bought for well under $20,000 these days. But what's the deal with those batteries? Can you be confident that a years-old Tesla will still perform well? In general, the answer is yes."
"But if you want to make sure your used Tesla's battery stays healthy for longer, Voltest's data shows, consider finding a Model 3 with a lithium iron phosphate (LFP) battery pack. This lithium-ion battery chemistry is known for its low cost, resilience to heat and high voltage, longevity and ability to be charged to 100% without damage. High-nickel chemistries, on the other hand, are far more popular in the U.S., pack more energy density (ie, range) and can support quicker charging, but they degrade faster."
Used Tesla Model 3s are common and affordable, with many available for under $20,000 and offering solid range, charging, and advanced software. Battery longevity is generally strong: Voltest data indicates about 70% of tested vehicles retain at least 80% battery health. Lithium iron phosphate (LFP) packs show greater resilience, tolerance for 100% charging, and slower degradation. High-nickel chemistries (like NCA) provide higher energy density and faster charging but degrade faster. A small Voltest sample compared 20 Model 3s over 100,000 miles—half LFP, half NCA—to illustrate real-world chemistry differences. OBD inspection tools can assess battery health.
