In an era where the value of a car is heavily influenced by fuel prices and environmental impact—especially with Singapore’s goal to phase out Internal Combustion Engine (ICE) vehicles by 2040—hybrid cars have gained popularity in recent years.
Like regular Internal Combustion Engines (ICE) vehicles, hybrid cars require maintenance.
However, they also contain a critical component that owners should pay special attention to: the hybrid battery pack. If left unmaintained, it can significantly affect the car’s performance.
In this article, we’ll share tips to help you determine whether your battery needs replacement and what to do next.
Signs that your hybrid car battery need replacement are :
Hybrid system warning light
If you have a modern hybrid vehicle, the easiest way to identify issues is through the dashboard. The first light that will typically appear is either the Check Engine light or the Check Hybrid System light. The Check Hybrid System light varies between different models, so be sure to check your manual for specifics.
Decreased battery charge
If you notice that the battery is recharging more slowly, especially during frequent braking, like in traffic, it may indicate that the battery pack has bad cells or is experiencing serious degradation due to age or usage. Another sign of this issue is if the battery struggles to reach 100% charge or loses power rapidly during electric-only drives.
Slow Acceleration & Decreased Power
Hybrid cars are known for their torquey acceleration, thanks to the assistance of electric motors. However, if you’re experiencing sluggish starts or a lag when accelerating, it could indicate that the hybrid battery is not delivering full power to the electric motors.
Poor fuel economy
Since hybrids rely on both the electric motor and engine to conserve fuel, it’s important to monitor your mileage. In Singapore, the average fuel consumption for hybrids ranges from 18 to 26 km/l, depending on the model. A good way to track this is by observing how frequently you need to refill your gas compared to your usual weekly average.
Strange noises
Typically, hybrid cars are quiet. So, if you hear unusual clicking or humming from the battery compartment, it might indicate that the battery is having trouble cooling itself. These noises can be subtle, so be sure to pay close attention.
What to Do Next?
If you’ve noticed any of the signs mentioned above, it’s essential to take action to prevent further damage and ensure your vehicle remains safe and efficient. Here are the steps you can take:
1. Consult Your Vehicle’s Manual
Before you start panicking about the issues on your car, you should look up your owners’ manual to seek guidance on interpreting the warning lights that may flicker on your dashboard.
2. Visit a Certified Mechanic or Dealership
Hybrid batteries are complex components and should be handled by a professional. You can do so by going to your dealership, or you can contact a specialist near you.
3. Consider Reconditioning vs. Replacement
Depending on the severity of the battery, you may not need to get a full replacement. Some hybrid batteries can be reconditioned, which involves restoring the battery to its original state by recharging, deep-cycling, and replacing defective cells. However, this is not a permanent solution.
4. Research Replacement Costs
If the battery needs replacing, do your research by gathering quotes from certified shops and dealerships. Battery replacement for hybrids can be expensive, ranging from SGD 2,000 to SGD 6,000 or more, depending on the model and battery type.
FAQs
How often should I get my hybrid car battery checked?
It is recommended to have your hybrid car battery checked once every year or about once every 20,000 KM. This is done to identify any issue early before it turns into anything serious.
How can I extend the life of my hybrid battery?
Frequent maintenance, avoiding extreme temperatures, and not letting the battery charge drop too low can help extend its life.
Can I perform hybrid battery maintenance myself?
No, Unless it is just for cleaning the battery. Complex repairs for the battery is recommended for those with expertise in the matter as it can be very hazardous.
Can I Drive A Hybrid Car If The Battery Is Completely Dead?
Most hybrid vehicles have a backup internal combustion engine that can still operate the car if the battery is depleted, but it’s important to have the battery checked and repaired as soon as possible to maintain optimal performance.
Is it worth replacing a hybrid car battery?
Whether it’s worth replacing depends on the overall condition of the car. If your vehicle is in good shape, replacing or reconditioning the battery can extend its lifespan significantly. However, if the car is older and requires additional repairs, you may want to consider the total cost before deciding on battery replacement.
