How Long Does a Tesla Battery Last?
2 Answers
Tesla's official data on battery lifespan is 450,000 to 600,000 kilometers, roughly equivalent to about 20 years of use. Relevant information is as follows: 1. A Tesla battery unit is composed of over a dozen small packs, with each small pack consisting of more than 70 individual batteries. The higher the electric vehicle's range, the larger the battery capacity. 2. Tesla's battery pack is made up of over 7,000 18650 batteries. The lifespan of 18650 batteries is calculated based on charge-discharge cycles, approximately 1,000 cycles. If charging once every 2 days, the battery would last around 2,000 days, meaning the battery would need replacement roughly every 5 years. Of course, the actual usage of the vehicle will determine the specifics.
I've been driving a Tesla Model 3 for three years now, and the battery condition is still quite good. Tesla batteries typically last 8 to 10 years or around 120,000 miles, depending on driving habits. Personally, I try to avoid letting the charge drop below 20% or charging to 100%, and I mostly use standard charging instead of Superchargers to prevent battery degradation. Temperature has a big impact, so I preheat the battery when parking in cold winter weather. Tesla's official warranty covers 8 years or 100,000 to 150,000 miles (depending on the model). My friend has been driving a Model S for almost five years, and the capacity has only dropped to 93%, with less than 2% degradation per year. Although the battery will eventually need replacement, costing several thousand dollars, there's no need to worry if you take good care of it daily.
