Hybrid cars use both battery and engine to power the car and they can offer many advantages over conventional cars. However, you might wonder: Can you still drive a hybrid without the battery? In this blog, we will explore this question and answer other similar queries.
Can You Still Drive a Hybrid Without the Battery?
The answer to this question depends on the type of hybrid car you have and the condition of the battery. Hybrid cars have two batteries: a high-voltage hybrid battery and a 12-volt auxiliary battery. You can still drive a standard hybrid car without the battery as the car can still run on the gasoline engine. However, you will lose all the benefits of the hybrid system.
Other hybrid cars, such as plug-in hybrids may not be able to run at all. So, it is not a good idea to drive a hybrid without a battery, as it can be risky and expensive over time. The best way to keep your hybrid car running well is to take care of the battery and replace it when needed.
What Happens If a Hybrid Car Battery Dies While Driving?
Different hybrid cars have different programs that control how the battery and the engine work together.
1. Switching to Internal Combustion Engine
In some hybrids, if the battery is low on charge, the car will switch to the ICE (Internal Combustion Engine) drive and use petrol or diesel to keep moving. It will also recharge the battery by itself. This means that you don’t have to worry about the battery charge as long as you have fuel in your car. This is how most hybrids work when you drive them in normal mode (not electric-only mode).
The mechanism of the car works such that it will not let the battery run out of charge completely. So, even if the car has no gas and is running only on battery power, it will stop with a bit of charge left in the battery, not enough to move the car, but enough to save the battery.
2. Stop Engine
Some hybrids may have different programs that make the car stop if the battery is dead. The car will sense that something is very wrong and will stop everything to prevent more damage. The first signs of a dying high-voltage battery are more gas usage and more engine noise. This can happen gradually, so you may not notice it soon. If the 12-volt battery fails, the engine will not start and that will also make the car stop even if the battery is full.

How Do You Start a Hybrid Car with A Dead Battery?
You cannot jump-start the high-voltage hybrid battery that runs the electric motor, but you can jump-start the 12-volt auxiliary battery that runs the accessories and the ignition system. However, you need to follow the manufacturer’s instructions and safety precautions carefully, as jump-starting a hybrid car incorrectly can cause serious damage or injury.
How to Jump-Start
To jump-start a hybrid car with a dead battery, you will first need the following:
- Either a jump-starting battery pack or another car with jumper cables.
- Locate the 12-volt auxiliary battery and the jump-starting terminals in your hybrid car.
The location of these components may vary depending on the make and model of your car, so you should consult your owner’s manual or a reliable online source.
Here are the general steps to jump-start a hybrid car with a dead battery:
Step 1: Turn off both cars and make sure they are in park or neutral with the parking brake on.
Step 2: Connect the positive (+) cable to the positive (+) terminal of the jump-starting battery pack or the other car’s battery.
Step 3: Connect the other end of the positive (+) cable to the positive (+) jump-starting terminal of your hybrid car.
Step 4: Connect the negative (-) cable to the negative (-) terminal of the jump-starting battery pack or the other car’s battery.
Step 5: Connect the other end of the negative (-) cable to a metal ground point on your hybrid car, such as the engine block or a bolt. Do not connect it to the negative (-) jump-starting terminal of your hybrid car, as this can cause sparks or damage.
Step 6: Turn on the jump-starting battery pack or start the other car and let it run for a few minutes.
Step 7: Try to start your hybrid car. If it starts, disconnect the cables in the reverse order and let your car run for at least 30 minutes to recharge the battery. If it does not start, check the connections and try again.
Step 8: If it still does not start, you may need to replace the battery or seek professional help.

What Happens If You Drive a Hybrid with A Dead Battery?
Driving a hybrid with a dead battery can have negative effects on the performance, efficiency, and safety of the car. A dead battery means that the electric motor cannot assist the gasoline engine, which results in the following:
- Lower power output and higher fuel consumption
- The regenerative braking system cannot function, which reduces the braking efficiency and increases the wear and tear of the brake pads.
- Damage the engine or the electric system, as they may overheat or overload due to the lack of battery support.
Therefore, driving a hybrid with a dead battery is not advisable, as it can be dangerous and costly in the long run. It is better to maintain and replace the hybrid battery properly to ensure the optimal functioning of the car.
How Much Does It Cost to Replace a Hybrid Battery?
The average cost of replacing a hybrid battery for different car brands and models ranges from around $1,000 to $8,000, or more. However, this is merely a rough estimate based on research and the actual cost may differ depending on your specific circumstances.
The cost of replacing a hybrid battery depends on several factors such as the make and model of your car, the age and condition of the battery, the type and size of the battery, and the labor and installation fees.
1. Type and size of the battery: Different hybrid cars use different types of batteries, such as nickel-metal hydride (NiMH), lithium-ion (Li-ion), or lead-acid. The size of the battery also varies depending on the power output and range of the car. Generally, larger batteries are more expensive than smaller ones.
2. The warranty coverage of your hybrid car: Some hybrid cars have a pre-determined replacement interval for the battery of 10 years or 150,000 miles, while others may require you to check for signs of degradation or failure before replacing it.
3. The availability and quality of parts: Some parts may be harder to find or more expensive than others due to supply chain issues or high demand. You may also want to consider buying a refurbished or used battery pack if you want to save money.
4. The labor and installation fees: Replacing a hybrid battery requires specialized tools and skills that not all mechanics have. You may need to pay extra for diagnosis, programming, testing, or disposal of your old battery. You may also need to pay for transportation or towing if your car is not drivable.
Here are the average estimated prices for hybrid battery replacements for different car makers.
- Toyota: £1,500 – £6,000
- Honda: $2,000 – $8,000
- Ford: £4,000 – £7,000
- BMW: £4,000 – £11,000
- Mercedes: £5,000 – £15,000
To get a more accurate quote for replacing your hybrid battery, you should contact your local dealer or mechanic and provide them with your car’s make, model, year, mileage, battery type, and size. They will be able to give you an estimate based on their experience and expertise.

Do Hybrid Cars Charge Battery While Driving?
Yes, hybrid cars can charge the battery while driving. This is achieved by the use of the internal combustion engine to generate electricity and recharge the battery while driving or idling.
Some hybrids also use a process known as regenerative braking, where the energy produced during braking is converted into electricity and used to recharge the car’s battery. This way, hybrid cars can optimize their fuel efficiency and reduce their emissions by using both the battery and the engine in different situations.
A plug-in hybrid electric vehicle (PHEV) has a bigger battery than a regular hybrid. Therefore, it may not be enough to charge the battery by using the engine and regenerative braking while driving, as normal hybrids do. It may also need to be plugged into an external power source. However, Hybrid cars are a smart option for drivers who want to spend less on gas, lower their environmental footprint, and have a smooth and quiet ride.
