Britain only ever got one version of this generation, the ES 300h hybrid saloon. There was no petrol-only ES here and no plug-in, so any ES on a UK plate is a 300h. Registration years in this category:
Trim grades sold here were ES, Premium Edition, F Sport and Takumi. The F Sport rides on different suspension and the Takumi carries more equipment, but the hybrid pack underneath is shared across the range. Lexus updated the car for the 2022 model year, so later examples differ from launch cars in places.
Registration year is a starting point, not proof of fit. We read the vehicle record first. See the 2019-2025 Lexus ES 300h battery replacement listing, then call with your registration to hand.

Lexus put the pack under the rear seats on this generation instead of in the boot. Two things came from that. Luggage room went up, and weight moved further forward, which helps the car settle on a motorway. It also means a technician reaches the battery from inside the cabin.
One caution. This model line did not use the same battery chemistry in every market across all seven years. We check the pack against your individual car rather than assuming from the year on the logbook.
Capacity falls away slowly, so the first clues are usually feel and fuel rather than a light on the dash.
| What you notice | What it can also point to |
| Fuel economy well down on normal | Tyres, driving pattern, cold weather |
| Engine running more of the time | A blocked or failing battery cooling fan |
| Weak electric help when pulling away | A fault elsewhere in the hybrid system |
| Charge gauge swinging up and down quickly | A sensor or software issue |
| Braking feels less consistent when slowing | The brake system rather than the battery |
| Warning messages on the driver display | Any number of hybrid components |
The right-hand column is the point. Plenty of ES cars arrive with battery symptoms and a different cause behind them. We test before we recommend anything, and we say so when the pack turns out to be fine.
The battery works as part of a managed system. Its condition is monitored constantly, and the car decides how hard the engine and motors work based on what the pack can deliver. Fit a unit the car cannot manage properly and you get poor running or fresh faults instead of a fixed car.
We test a replacement before it goes in, so its condition is known rather than assumed. High-voltage work also needs correct isolation, the right equipment and people who do it regularly, which is why this is not general garage work. Once the new pack is fitted, the car goes out for a check drive before it is handed back.
Cover is set out in our battery warranty policy, and the terms that apply to your car are confirmed against the pack you go with.
| Stage | What Lexus UK provides |
| With qualifying servicing | Hybrid battery cover up to 10 years or 100,000 miles |
| After that point | Cover extended a year at a time with an annual Hybrid Health Check |
| Upper limit | Until the car is 15 years old |
Lexus does not publish a figure for how long the pack itself lasts. It says life depends on use, driving style and upkeep. Because UK ES cars only start at 2019, most are still on their first battery, and the ones reaching us tend to be high-mileage company cars. Our guide to hybrid battery warranties in the UK goes through how manufacturer cover works in practice.
Hybrid and EV packs are all we do. That narrow focus is the reason ES owners travel to us rather than to a general workshop.
More on how the business runs is on our About Us page, and battery recycling explains where the old pack ends up.
Everything is carried out at our workshop in Trafford Park, Manchester. ES enquiries reach us from drivers in London, Manchester, Birmingham, Leeds and Liverpool.
Details for visitors are on the Manchester page, and the service areas page shows the wider coverage. Ring ahead so we can look up the car and check availability before you set off.

Useful to have ready: registration number, year of registration, rough mileage, and what the car has started doing differently. If a warning message has appeared, note when it tends to show up.
Also worth a look: the full EV and hybrid battery replacement range, or nearby Lexus models such as the IS 300h, NX and RX.

Ben and George are absolutely amazing! I came in after learning my Toyota Hybrid battery needed replacing. They took me through the work that needed doing, took photos of the process and repaired my hybrid battery. Since having the work done, my car drives smoothly and I feel confident driving it again!

I am one of Greentec earliest customers in Manchester. They replaced my Tesla model 3 performance battery. The full range is back to 303 miles. Ben kept in close contact during the process. The car runs perfectly. Highly professional, very skilled and significantly lower cost the Tesla. I highly recommend their services

Meeting Ben and George was a great experience, both incredibly friendly, enthusiastic and clearly knew their stuff – Took me through the whole process and were greatly accommodating as well. Picking the car up was an equally great experience, showed me top to bottom how they’d diagnosed the issue, what they’d found (some components may as well have been charcoal they were that corroded), how they fixed it and included pictures of the whole process. Thanks again guys, great stuff.

Their technical knowledge of Tesla vehicles was very reassuring, and it was clear they knew exactly what they were doing. The cost was also very reasonable, especially considering the quality of the work and the level of expertise involved. Everything was handled efficiently and professionally, and the car was back on the road quickly. Overall, I’m extremely happy with the service I received and wouldn’t hesitate to use Greentech Auto again in the future. Highly recommended for anyone needing reliable and knowledgeable EV service.

A massive thanks to Ben and George We came to you after our bmw x5 showed problems with the charging system BMW at Sheffield wanted to charge us 5k for the repair to the battery safety box. We also tried two independents at Sheffield neither were interested in diagnosing the problem. Ben and his team came way under the quoted price from bmw and talked me through what was needed, kept me informed of every step of the repair We now have a car that is in fully working order. I would highly recommend anyone with a problem with a EV to try greentec Very happy customer

UK Lexus ES 300h cars use a nickel-metal hydride pack of around 245 volts, fitted under the rear seats. Lexus used lithium-ion for this model in some other markets during the same period, which is why the battery should be confirmed against the individual car rather than the model year alone. The pack is charged by the petrol engine and by braking, not from a plug.
Cars registered from 2019 to 2025 are covered, taking in the whole seventh-generation ES sold in the UK. Trim makes no difference to the battery. ES, Premium Edition, F Sport and Takumi cars all use the same hybrid pack, so the F Sport suspension and the extra Takumi equipment do not change the replacement.
Lexus moved the pack from the boot to beneath the rear seats when this generation launched, which freed up luggage space and shifted weight forward for better balance. There is a second benefit for owners. The battery is reached from inside the cabin, so access is simpler than on models that carry the pack in the boot.
A car with a tired pack will usually still drive, but it will use more fuel, feel less smooth, and lean harder on the petrol engine. Any hybrid system warning message should be looked at promptly rather than left, since the same symptoms can come from other parts of the system. Have the car tested so you know whether the battery is genuinely the cause.
Call Greentec Auto UK on 0808 1966398 with your registration number and model year, or send the details through the contact form. The team confirms which pack fits your car and checks availability before you travel to the Manchester workshop. Enquiries come in from drivers across London, Manchester, Birmingham, Leeds and Liverpool.
