Tesla Batteries vs. Engines: A Debate on Betterment and Insurance Claims

A recent call log with a Tesla owner highlights an interesting situation, raising questions about how insurance carriers should handle claims for electric vehicles (EVs), particularly regarding betterment. The owner was involved in an accident where their Tesla’s battery was damaged. The insurance carrier initially wanted to apply betterment, treating the battery like a standard car battery. The owner argued that a Tesla battery is more like an engine, and betterment shouldn’t apply in this case. After a tough fight, the owner managed to have the betterment removed from the claim. This situation warrants a discussion on the similarities between Tesla batteries and engines and the potential implications for insurance claims.

Tesla Batteries vs. Engines: The Similarities

Essential Components

Both engines and Tesla batteries are critical components of their respective vehicles. While engines are the primary source of power in traditional internal combustion engine (ICE) vehicles, batteries play the same role in EVs like Teslas. In both cases, the vehicle cannot function without these components.

Cost and Value

Tesla batteries are expensive, similar to engines in ICE vehicles. They represent a significant portion of the vehicle’s overall value. Moreover, both components have a long lifespan and require regular maintenance to ensure optimal performance.

Technological Advancements

Both engines and Tesla batteries are subject to continuous improvements in technology. Newer models typically offer better efficiency, performance, and longevity, making older models potentially less valuable over time.

Why Betterment Shouldn’t Apply to Tesla Batteries

Inherent differences

Unlike standard car batteries, which mainly serve to start the engine and provide power to accessories, Tesla batteries are the primary source of power for the entire vehicle. They are not a simple wear-and-tear item, as they have a longer lifespan and are subject to regular maintenance.

Warranty considerations

Tesla offers an extensive warranty for its batteries, which can last up to eight years or more, depending on the model. The warranty covers a wide range of potential issues, which may not be the case for traditional ICE vehicle engines.


While betterment is intended to account for the depreciation of an older component being replaced with a newer one, Tesla batteries typically have a slower rate of depreciation than traditional car batteries. This is due to their long lifespan, warranty, and regular maintenance.

To wrap it up…..

The debate surrounding the classification of Tesla batteries as engines and the application of betterment in insurance claims is a complex one. Given the similarities between Tesla batteries and engines, as well as the inherent differences between EV batteries and standard car batteries, it is reasonable to argue that betterment should not apply in cases like the one discussed. Insurance carriers need to reconsider their policies and adapt to the changing landscape of automobile technology, ensuring fair treatment for EV owners in accident claims.
