This is part 2 of our car know-how series, where we help car owners understand car battery replacement. See part 1 on Engine Oil Change here.
1) What does a car battery do?
Without a functioning car battery, your car engine will not start
The car battery powers all the electrical systems in the car and this includes the engine starter, lights and sound system.
Once the engine is running, the car battery charges, allowing it to perform its functions once again.
2) Why does a car battery fail?
The most common reasons for battery failure are drainage, being worn out, or a faulty charging system
Car battery failure could come unexpectedly and be very disruptive. There are a few reasons why a battery might fail:
The car battery is drained: This commonly occurs when lights are left on without the engine running, draining the car battery of its power. In this case, the car battery will need to be recharged.
The car battery is nearing the end of its lifespan: This is typically 2 years in Singapore, shorter than other countries due to the hot weather. This will result in the battery being unable to hold its charge very well.
The charging system is faulty. This results in an improper charge, resulting in a dead battery.
3) What to do when my car battery fails?
We recommend calling for an emergency car battery service
There are two main options for car owners intending to fix their car battery.
Call for an emergency car battery service: There are 24 hour emergency services that are able to change your car batteries at your location, available here.
Jump start only if you have experience doing so: We recommend jumpstarting your car1 only if you confident enough to do it.
Alternatively, you can ask Steer if you need help urgently.
4) What types of car batteries should I use?
Depends on your car; we recommend checking your car manual
Car batteries can be categorized into “group sizes”, which are typically based on your vehicle’s make, model and engine type.
While some vehicles can accommodate a battery from more than one group size, it is important to use a battery approved for use in your vehicle. This will ensure your battery fits well in your vehicle.
A larger group size typically means a larger battery and consequently higher energy storage.
We recommend checking your car manual or consulting your mechanic for the appropriate car battery to use. Alternatively, you can ask Steer.
5) How much does a car battery replacement cost?
A standard car battery typically costs $100-130 at the workshop and $140-180 for onsite servicing
Commonly included in a regular servicing is a check on the life of your battery. Your mechanic might recommend a replacement if your battery is nearing the end of its lifespan. The price to do so is typically between $100-$130.
Mobile car battery replacement services are also available, sometimes on a 24 hour / 7 days a week basis. As you are paying for the mechanic to get to your location, these services typically cost more, at around $140-180.
These prices are for a standard car battery, suitable for most small and medium cars. Larger car batteries could cost up to $300. Depending on your car make and model, prices could vary.
For quotations and pricing, you can ask Steer.

1 You can jump start your car with help of another car and jumper cables. This can be done by 1) attaching the red cable to both cars’ battery positive terminal. 2) The black cable should be attached to the working car’s negative terminal and a grounded metal component of the car that contains the dead battery. 3) This is followed by turning on the engine of the working car. 4) Wait for five minutes before starting the car with the dead battery. 5) If the jump works, drive the car around for 20 minutes so the previously dead battery charges up.
