Electric Vehicle Battery Warranties FAQs - Everything You Need to Know

EVs are relatively new, so finding accurate and relevant information on an EV’s battery warranty can be difficult, especially considering we’re dealing with a piece of technology that begins to lose performance as you drive.

To make things even worse for buyers, a potential battery issue or replacement can total tens of thousands of dollars, so you must have all the information to answer your questions ahead of time for the best, informed decision.

In this piece, we’ll be taking a look at everything you need to know about an electric vehicle’s battery warranty, as well as breaking down each warranty program from every manufacturer selling an EV in Australia in 2024.

What is an Electric Vehicle Battery Warranty?

If you’ve looked closely at the fine print, you’ve likely noticed that electric vehicles are packaged with both a vehicle warranty and a battery warranty.

The vehicle warranty is offered by the manufacturer and will cover the cost of any repairs and/or replacements necessary to fix a factory fault relating to the safety or durability of that vehicle.

What is Covered in an EV Battery Warranty?

An electric vehicle’s battery warranty, on the other hand, is offered by the manufacturer and will cover costs incurred to replace or repair an issue with the battery pack.

Perhaps more importantly, an EV warranty should offer buyer protections in the case of an underperforming or rapidly degrading battery pack that can’t hold a charge over time.

An EV battery warranty gives buyers protections in the case the battery pack underperforms in terms of capacity, with the manufacturer footing the bill for any material and labour costs associated with either fixing your current battery or replacing it with a new pack.

What Voids an Electric Vehicle Battery Warranty?

Neither a vehicle warranty nor a battery warranty includes coverage for damage caused by an accident, misuse or ‘normal wear and tear,’ the latter of which applies more to the vehicle warranty.

That is because an electric vehicle battery is often mounted deep atop or inside the chassis, meaning it would be virtually impossible to damage the battery pack via wear and tear; damage caused would be either the result of questionable driving or a factory fault.

FAQ: What is the Longest EV Battery Warranty in Australia?

Currently, in 2024, China’s MG leads the way when it comes to the longest battery warranties, each offering eight years or 250,000 kilometres of coverage for the battery and high-voltage components, while the commercial LDV eDeliver7 receives the same warranty coverage over the standard 160,000k-kilometre warranty bundled with the rest of LDV’s electric range.

FAQ: Does my Battery Warranty Cover Loss of Charge and Degradation?

Typically, a manufacturer’s electric vehicle battery warranty does provide coverage in the case your vehicle’s battery pack experiences accelerated degradation, causing a loss of charge and less driving range per charge. Typically, this ensures a battery will hold a state of charge above 70 per cent after a certain period of time.

These degradation figures change between manufacturers, however, so it’s important to read the fine print on any model you’re tossing up to confirm whether or not there are specific degradation causes for a warranty claim.

FAQ: How Long Does an Electric Vehicle Battery Last?

The world of battery-electric motoring is rapidly developing, with several breakthroughs in battery chemistry and layouts resulting in significant lifespan increases over the first generation of EVs we saw hitting the market a decade ago.

As a result, it’s difficult to pinpoint exactly how long the battery of an electric vehicle being sold today will last, though a conservative estimate points to a lifespan upward of ten to fifteen years and anywhere between 300 - 350,000 kilometres. These figures do not take into account key factors like charging habits and things like extreme temperatures which have a huge impact on a battery’s lifespan.

FAQ: What is a Solid State Battery?

Solid-state battery technologies are set to provide potentially massive breakthroughs for the electric vehicle world.

A solid-state battery uses a solid electrolyte instead of the liquid or gel electrolytes found in traditional lithium-ion batteries. This looks set to dramatically increase energy density for more range per charge, improve performance in extreme temperatures and reduce fire risks.

For electric vehicles, solid-state batteries promise quicker charging times, lighter weight, and extended lifespan, which could lead to longer trips between charges and better overall vehicle efficiency.
