EV batteries are fascinating innovations, but this excitement quickly fades when facing electric car battery replacement costs. 

Luckily, replacing your battery isn't always as expensive as it seems. 

In this article, we'll discuss the average electric car battery replacement cost in the UK, factors that influence battery prices, warranties, and how to prolong battery life. Let's jump straight in!

How much does an electric car battery replacement cost?

The average electric car battery replacement cost is around £7,200 in the UK. 

Electric car battery replacements are usually necessary due to battery degradation, accidents, or faulty manufacturing.

Factors affecting the cost include battery size, type, vehicle make and model, labour costs, and advancements in battery technology. Also, batteries for premium cars tend to be more expensive to replace.

These elements will all affect your final fee. You can get a more accurate quote from a professional mechanic or dealership representative.

Electric car battery cost by car make

The make and model of your car significantly affect the price. So, it can be helpful to look at estimates for popular brands.

Here’s a quick overview of electric car battery replacement cost per car make in the UK:

Why is there a large difference in costs?

You may have noticed a big cost difference in the table above — but why?

Alongside car make, a significant factor in electric battery costs is battery size. For example, a large battery with over 100 KwH can easily cost over £11,000. In contrast, a smaller battery with as little as 50 KwH will cost around £5,000. 

Expect to pay more for a Tesla battery replacement than a Fiat 500e or Nissan Leaf!

Factors that affect electric car battery costs

Alongside make and model, you also need to consider the following factors:

• Type of battery (e.g. Lithium-ion)
• Battery size and capacity
• Availability of battery parts
• Battery manufacturing costs
• Labour and installation costs

Understanding these factors before shopping helps you make informed choices and manage expenses, keeping your EV in great shape without overspending!

What is the cheapest electric car battery replacement cost?

The Citroen Ami likely has the cheapest electric car battery replacement cost, as you can purchase a new one for around £600.

However, it’s critical to note that this short and sweet car only has 5.5 KwH. 

It has a maximum speed of 28 mph and isn’t legal for use on motorways or roads with speed limits above 30mph.

Great if you want to pop to the shops, but not an ideal candidate for road trips!

If you’re looking for a cheap electric car that can take you from A to B without speed restrictions, the Honda E is an excellent candidate. 

A Honda E electric car battery replacement costs around £3,000, making it much more affordable than most other models. Plus, you’ll likely have a warranty, so you won’t need to shell out for a replacement unless this period is over. Easy!

How often do you need to replace an electric car battery?

Most electric cars have a 10,000-mile or eight-year battery warranty since they’re built to last a long time. 

If your battery experiences a mechanical fault before the warranty expires, your manufacturer will completely cover the cost. 

Most manufacturers also tend to guarantee their batteries will retain about 70% of their original capacity after eight years. Most electric cars remain functional at this level, meaning you might not need a replacement for over a decade unless you own a small EV with a lower range. 

Even more good news—the technology keeps evolving. Maybe in the future, car batteries will outlast vehicles completely!

How to keep your electric car battery cost down

Finding the cheapest electric car battery replacement cost isn’t only about looking for fewer KwH. Maintaining your electric vehicle can also minimise potential repair costs. 

Here are our favourite extra tips to prolong your battery life:

• Regularly monitor the battery to identify issues earlier
• Make sure you service your car regularly to keep it in optimal condition
• Drive responsibly to ensure your car avoids damage
• Follow the proper charging instructions
• If a new battery is needed, compare costs from different suppliers to find a competitive rate

Can you repair an EV car battery?

Yes, in some cases, you can repair an electric car battery rather than just replacing it. 

For example, if the fault is minor, a specialist may be able to repair a single module. Mechanics with expertise in EV batteries will be able to identify the problem and offer tailored solutions. 

You shouldn’t try to repair an EV battery yourself if you have no experience. Always go to the experts for a safe and reliable repair!

Does car insurance cover an electric car battery replacement?

Most EV car insurance policies include coverage for battery replacement costs. 

However, you must check your policy details to know for sure. Some policies may only cover specific situations, such as theft or accidental damage — not battery replacement due to years of use. 

Remember, if your electric battery is still under warranty, you won’t have to pay for the replacement. Check your warranty and insurance for the best picture!
