Hybrid Battery Replacement Cost Guide

Hybrid battery replacement costs sit around £2,000+ for UK drivers. Sales of these vehicles have jumped in the last few years, making them one of the fastest-growing car choices. But battery technology remains their biggest limitation.

So, how long do hybrid batteries last, and what does it cost to replace them in the UK?

This blog breaks down the facts and answers to the key question: Is replacing a hybrid battery worth it?

Key takeaways

How much does a hybrid battery replacement cost?

In the UK, replacing a hybrid battery typically costs £2,000 or more, depending on the car’s make, model, and age.

While smaller and cheaper than full EV batteries, hybrid batteries are still expensive to replace. They also require specialist tools and expertise due to their high voltage, making DIY replacement dangerous.

Is it worth replacing a hybrid battery?

Replacing a hybrid battery is usually worth it if the rest of the car is in good shape.

If you’re unsure, compare the cost of a new battery with replacing the car entirely. You should also bear in mind that second-hand hybrids may come with hidden issues.

High mileage or multiple repair needs could tip the balance, but because hybrids are generally expensive to buy, investing in a new battery often makes sense. And if the upfront cost is a concern, you can spread the expense with car repair finance. This separates the cost into interest-free monthly payments.

Hybrid battery replacement costs by make and model

Replacing a hybrid battery can be costly, but prices vary depending on the make and model.

Toyotas are generally the cheapest hybrids to replace batteries for, but you can use the table below to compare typical costs in the UK.

Let’s take a closer look at popular models and the reasons behind the hybrid battery replacement costs.

Toyota Hybrid battery replacement cost

Replacing a Toyota hybrid battery varies by model and age.

On the Prius, costs range from £1,500–£4,000 for the second generation and £2,500–£6,000 for the third. Other models like the Auris, Yaris, Corolla, and RAV4 are typically more expensive (£3,000–£9,000).

The Prius, popularised over 22 years with 86,000+ UK sales, is one of the cheapest hybrids to replace, thanks to parts availability and multiple service options.

Older models are easier and cheaper to repair, while newer ones can be costlier due to limited service access and more complex technology.

Lexus hybrid battery replacement cost

Replacing a Lexus hybrid battery typically costs anywhere from £2,200 to £6,000.

While Lexus shares some parts with other luxury brands, hybrid batteries are mostly car-specific, so Toyota batteries don’t fit directly. Despite this, there’s a strong network of independent and specialist services offering replacements.

Lexus also provides a 15-year warranty if serviced at a dealership, which can cover costly hybrid system parts, making maintenance more predictable and potentially cheaper.

Mercedes hybrid battery replacement cost

At the higher end, replacing a Mercedes hybrid battery typically costs £7,000–£15,000.

Mercedes’ luxury hybrid models combine complex electrical systems with high-priced parts, making replacements significantly more expensive than most other brands.

Labour costs at Mercedes dealerships are also among the highest, adding to the overall cost of battery replacement.

How long do hybrid batteries last?

A hybrid battery typically lasts 100,000–200,000 miles with proper care.

Unlike fully electric vehicles, the battery shares the load with the petrol or diesel engine, reducing strain. The car’s computer manages power use, and the engine often recharges the battery.

Similar to a smartphone, keeping the battery topped up, avoiding full drains, and charging gradually helps extend its life.

Breakdown of hybrid battery replacement costs

If you’re searching for how much does it cost to replace a hybrid battery, you might also be interested in why they’re so expensive.

Here’s a quick rundown of what’s included in a battery replacement job.

• Material costs (E.g., for cobalt, lithium, and nickel)

• Manufacturing time and labour costs

• Research and development costs

• Distribution costs

• Disposal costs (some materials require specialised disposals)

Signs your hybrid battery is failing

It’s very uncommon for a battery to die without any signs, so learn the precursors below and keep them in mind.

• The battery is taking longer to recharge

• Losing charge very quickly

• Your car burns through petrol faster than it used to

Batteries tend to slowly degrade over time. Keep an eye on your car’s fuel efficiency and remember the signs of hybrid battery failure to stay ahead of repairs.

Do hybrid batteries have warranties?

Most hybrids include an 8-year/100,000-mile battery warranty, with some offering 10 years. Always check your warranty and insurance before booking a garage appointment, or you may not get the best deal.

How many batteries are in a hybrid car?

Most hybrid cars have two batteries: a standard 12-volt battery to power electronics and start the engine, and a high-voltage hybrid battery that stores energy for the electric motor and improves fuel efficiency.

Always check your car’s specifications or consult a professional garage to avoid booking the wrong service.

Can you drive a hybrid car with a dead battery?

No, you shouldn’t drive a hybrid with a dead battery.

If the high-voltage hybrid battery is dead, the car may still start using the petrol/diesel engine in some models, but the electric motor won’t function, fuel efficiency drops, and some hybrids won’t operate at all.

Always have it checked or replaced by a professional to avoid damage and ensure your car remains safe to drive.

How to check the battery health of a hybrid car?

To check a hybrid car’s battery health, start with the dashboard indicators and warning lights. Many hybrids provide a battery status display.

Familiarise yourself with the signs of a dead hybrid battery (listed above on this page), as these can help you notice any symptoms before the battery breaks.

You can also have a professional garage run a diagnostic using specialised tools, which measures voltage and capacity to ensure the battery is in good condition.

Can you jump a hybrid battery?

Jump-starting a hybrid’s standard 12-volt battery is usually possible, but the high-voltage hybrid battery cannot be jump-started. Attempting to do so is dangerous and can damage the car.

Always follow the manufacturer’s guidelines and, if unsure, have a professional garage handle any hybrid battery issues safely. Don’t tamper with what you don’t understand!
