What kind of battery is in the Lexus HS250H starter?
The Lexus HS250h, a hybrid luxury sedan, combines a gasoline engine with an electric motor to deliver efficient performance. One of the key components of this hybrid system is the starter battery, which plays a crucial role in powering the vehicle's electrical systems and starting the engine. In this article, we’ll explore the type of battery used in the Lexus HS250h starter and provide insights into its maintenance and replacement.
Understanding the Lexus HS250h Starter Battery
The Lexus HS250h uses a 12-volt auxiliary battery to power its starter and onboard electronics. Unlike traditional vehicles that rely solely on a lead-acid starter battery, the HS250h’s hybrid system also incorporates a high-voltage hybrid battery for propulsion. However, the 12-volt battery is specifically responsible for starting the car and running accessories like lights, radio, and navigation systems when the engine is off.
Specifications of the 12-Volt Starter Battery
The 12-volt battery in the Lexus HS250h is typically an AGM (Absorbent Glass Mat) battery. AGM batteries are preferred in hybrid vehicles due to their durability, efficiency, and ability to handle the frequent charging and discharging cycles associated with hybrid systems. Here are the key specifications:
- Type: AGM (Absorbent Glass Mat) battery
- Voltage: 12 volts
- Capacity: Approximately 45-55 Ah (Ampere-hours), depending on the model
- Location: Trunk area, typically on the passenger side
These specifications ensure that the battery can reliably support the vehicle's electrical demands and hybrid system requirements.
Signs Your Lexus HS250h Starter Battery Needs Replacement
Over time, the 12-volt battery in your Lexus HS250h may degrade and require replacement. Here are some common signs that indicate it’s time to replace the battery:
- Difficulty starting the vehicle or a complete failure to start
- Dim or flickering interior and exterior lights
- Warning lights on the dashboard, particularly the battery or hybrid system warning
- Unusual electrical issues, such as malfunctioning accessories
If you notice any of these symptoms, it’s essential to have the battery tested and replaced if necessary to avoid being stranded.
Tips for Maintaining Your Lexus HS250h Starter Battery
Proper maintenance can extend the life of your 12-volt battery and ensure reliable performance. Here are some tips:
- Regularly inspect the battery terminals for corrosion and clean them as needed.
- Ensure the battery is securely mounted to prevent vibrations that can damage it.
- Avoid leaving lights or accessories on when the engine is off to prevent draining the battery.
- Have the battery tested during routine maintenance to monitor its health.
By following these tips, you can maximize the lifespan of your Lexus HS250h starter battery and avoid unexpected issues.
Conclusion
The Lexus HS250h relies on a 12-volt AGM battery to power its starter and electrical systems. Understanding the specifications, recognizing signs of wear, and maintaining the battery properly can help ensure your vehicle operates smoothly. If you suspect your battery needs replacement, consult a trusted auto service provider to ensure the job is done correctly.

Frequently Asked Questions
Which battery does a hybrid use to start?
12-volt battery
Hybrid vehicles use both a conventional 12-volt battery and a high-voltage battery pack. If the 12-volt battery dies, the car won't start. However, jump-starting a hybrid car is similar to jump-starting a traditional vehicle, requiring only a few tools and precautions.
What type of battery is a starter battery?
lead-acid battery
What starter batteries are there? The most common battery is and remains the lead-acid battery. This battery type consists of six cells which are made up of positive and negative electrodes. Positive electrodes are made of lead oxide, while negative electrodes are made from pure lead.
Why did Lexus stop making the hs250h?
In an e-mail response to an Inside Line query, Toyota said: “Production of the HS 250h ceased in January, 2012. Lexus continues to monitor sales for each product and we make adjustments to make sure that we meet market demand, and the discontinuation of HS was part of that adjustment.
What kind of battery is in a jump start?
Lithium-Ion battery
Jump starters work by using a special high current Lithium-Ion battery to provide enough power to start your engine. These batteries are rechargeable, and newer products should be able to not need a recharge for over a year (unless they've been used multiple times).
Will a jump starter start a completely dead battery?
A good quality portable jump starter can typically start a completely dead battery, thanks to modern technology advances. Today's jump starters use powerful lithium-ion batteries that can deliver the significant cranking amps needed to start a vehicle with a fully discharged battery.
Does the Lexus 450H have two batteries?
To recap, Lexus hybrids generally contain two batteries: a 12-volt battery (which powers systems such as the headlamps and audio) and a high-voltage hybrid system battery (which supplies the power to start the combustion engine and drive the electric motors).
How many batteries does a 2010 Lexus HS250h have?
The HS250h contains a sealed lead-acid 12 Volt battery. The 12 Volt auxiliary battery powers the vehicle's electrical system similar to a conventional vehicle.
Does Lexus hybrid have two batteries?
Fortunately, most hybrids have two batteries: a hybrid battery and a much smaller battery to operate the electronics in your vehicle.
How much does it cost to replace the battery in a Lexus HS250h?
The average cost for a Lexus HS250h Battery Replacement is between $318 and $325. Labor costs are estimated between $26 and $33 while parts are typically priced around $292. This range does not include taxes and fees, and does not factor in your unique location. Related repairs may also be needed.
What type of battery does Lexus hybrid use?
nickel-metal hydride batteries
Lexus primarily uses a 12-volt lead-acid battery for its conventional vehicles and incorporates high-voltage nickel-metal hydride batteries for its hybrid models.
