How many kWh battery is in the Lexus ES 300h?

The Lexus ES 300h uses a nickel-metal hydride (NiMH) battery with a capacity of about 1.3 kWh. This pack provides the electric assist to the hybrid system and is not designed to be plugged in for charging.

Battery specifications

Key numbers at a glance

Details of the ES 300h's high-voltage battery are listed below to describe its role in the hybrid system and how it's configured.

• Battery type: Nickel-metal hydride (NiMH)


• Capacity: Approximately 1.3 kWh


• Nominal voltage: Around 200 V (commonly cited around 201.6 V in Toyota/Lexus hybrids)


• Chemistry and design: Built for rapid charge/discharge via regenerative braking and engine assist; sealed construction for durability

In short, the ES 300h relies on a compact NiMH pack that largely serves to smooth transitions between electric and gasoline power and to boost efficiency.

Driving implications

Plug-in vs. non-plug-in operation

The ES 300h is a self-charging hybrid and does not offer plug-in charging. The high-voltage pack recharges during braking and when the engine drives the wheels. Electric-only driving is limited to low speeds or light throttle, with the gasoline engine taking over at higher speeds or heavier acceleration.

• Plug-in charging: Not available; battery recharges through the hybrid system.


• Electric-only range: Limited to short distances, typically a few miles or less.


• Fuel economy impact: The battery helps improve efficiency by enabling torque assist and smoother engine operation.

Thus, the battery's primary role is to enable efficient hybrid operation rather than to provide extended electric-only driving.

Summary

The Lexus ES 300h uses a compact 1.3 kWh NiMH battery as part of its self-charging hybrid system. This pack supports the electric motor for fuel-efficient operation and regenerative charging, but it is not a plug-in battery and does not offer long-range EV driving.

How long does a Lexus 300h hybrid battery last?

A Lexus 300h hybrid battery typically lasts between 8 to 15 years or 100,000 to 150,000 miles under normal conditions, though factors like climate and driving habits can impact its lifespan. Proper maintenance, such as regular service checks, avoiding extreme temperatures, and ensuring the battery is securely fastened, can help extend its life. 
Factors affecting battery life

• Usage and conditions: Driving habits, the climate you live in, and whether the car is stored indoors or outdoors all play a role. 
• Maintenance: Regular inspections and keeping the battery securely fastened can help prolong its life. 
• Battery health: A battery's performance may degrade over time, leading to reduced electric range and fuel efficiency. 

Extending battery life

• Secure the battery: Ensure the battery is mounted securely to prevent damage from vibrations. 
• Control temperature: Store the vehicle indoors when possible to protect the battery from extreme temperatures. 
• Drive regularly: Consistent use is better for the battery than letting it sit idle for long periods. 
• Perform maintenance: Have your battery inspected at service intervals and clean any corrosion from the terminals and posts. 

What is the range of the Lexus ES 300h EV?

Lexus ES 300 Electric Mileage
For the range, expect to get between 567 to 581 miles on a single tank of gas thanks to the hybrid powertrain, which runs on a 2.5L inline 4-cylinder engine generating 215 hp.

What is the best year for the Lexus ES 300h?

The best year for a Lexus ES 300h depends on priorities: the 2013-2018 models are often cited for their reliability and value, while the 2019 and newer models represent the latest generation with more modern styling and technology. For value, consider the 2016 facelift, which brought updated styling but less modern tech, and for the newest features, look at the 2022 or 2023 model years for features like the updated safety system and touchscreen, respectively.

Best for value

• 2013-2018 (6th Generation): This generation is praised for its reliability and, for older models, is often available at a lower price point. 
• 2016 (Facelift): If you want a more modern look without the higher price of the newest models, the 2016 refresh is a good compromise with updated interior and exterior styling. 
• 2019-2022: These are part of the most current generation and offer a great balance of modern features and proven reliability at a price point below the newest models. 

Best for latest technology and features

• 2022-Present (7th Generation): These models are in the most recent generation and feature updated safety systems and technology.
• 2023 and newer: These years offer a new touchscreen interface, which some drivers may prefer over the previous touchpad controls. 

Key factors to consider

• Price: Older models (2013-2015) can be found for significantly less than newer ones. 
• Technology: Later models have more advanced features like a new infotainment system and updated safety features. 
• Styling: If you prefer the more modern and updated styling, you'll want to look at models from the 7th generation (2019 and newer).
