FAQ about Car Batteries

General Car Battery Knowledge

Are there different type of car batteries?

At Battery Empire, we carry the following batteries that are suitable for cars, vans, lorries & trucks:

JIS (Japanese Industrial Standard) – Suitable for Japanese & Korean vehicles

DIN (Deutsches Institut für Normung [German Institute for Standardisation]) – Suitable for Continental vehicles

What are the common causes of car battery failure?

  1. Manufacturing Faults
    Typically occur within the first 3 months.
  2. Wear and Tear
    As a battery ages, grid metal corrodes and active material is lost from the plate. Over time this leads to a point where the battery will no longer be able to start a vehicle. High temperature will accelerate the degradation rates.
  3. Physical Damage
    Incorrect fitment, handling and storage often leads to external damage and subsequent battery failure.
  4. Negligence
    Lights or other accessories left on for extended periods.
  5. Sulphation
    Occurs when the battery is allowed to stand in a discharged state for an extended period of time.
  6. Over-Charging
    Often caused if the alternator is incorrectly set or the alternator voltage control fails.
  7. Under-Charging
    Short journeys, stop start driving or faulty alternators will not fully recharge a battery.
  8. Discharge
    Lights or other accessories left on for extended periods.

What are the major difference in the car battery brands?

We carry 4 tiers of car batteries to cater to every driver’s different needs:

  1. Budget Battery – 2nd hand battery for drivers whose car is going to be scrapped or selling off.
  2. Economy Battery – For drivers who have a tighter budget.
  3. Good Battery – For drivers who are looking for the bestselling battery brand in the market.
  4. Premium Battery – For brand conscious drivers.

Can I use any type of car batteries?

All the major brands that we carry are suitable to be used in cars, vans, lorries and trucks.

Is there any official way to test the state of health of the car battery?

Yes, by using a battery tester. At Battery Empire, we only used the best in the market, imported from USA.

What are maintenance free car battery?

A VRLA battery (valve-regulated lead-acid battery), more commonly known as a sealed battery (SLA) or maintenance free battery, is a type of lead-acid rechargeable battery. Due to their construction, the Gel and AGM types of VRLA can be mounted in any orientation, and do not require constant maintenance.

Do you offer car battery testing service?

Yes we do at our workshop, however, advance booking need to be made to avoid disappointment. A service fee of $10 is chargeable without battery replacement.

Car Battery Maintenance Information

Car Battery Maintenance Guide

Regular testing and inspection will help to maximise battery life. A routine inspection at least once a month is recommended to maintain optimum performance.

Use the following as a guide when examining your battery:

  1. Ensure the battery top is clean and dry, free of dirt and grime. A dirty battery can discharge across the grime on top of the battery casing.
  2. Inspect the terminals, screws, clamps and cables for breakage, damage or loose connections. These should be clean, tight and free of corrosion.
  3. Inspect the battery case for obvious signs of physical damage or warpage. This usually indicates the battery has overheated or has been overcharged.
  4. Do not leave lights or other accessories left on for extended periods.
  5. To prevent the inconvenience of a roadside breakdown, make it a point to have a periodic replacement of your car battery, and avoid replacing the car battery only when it has died.

Starting up Car and Turning off the Engine

As a Rule Of Thumb, always turn off accessories before turning off the engine to guarantee maximum battery life and minimum strain on related components. Things like your car stereo, aircon, headlights and other accessories tax the vehicle’s electrical system. Starting the car draws on the same system heavily; if your battery is being tasked with running accessories and your starter motor at the same time, it’s going to have to work a little harder. As an illustrative example: if you start your car with the headlights on, you may notice them dimming as you crank the starter.

Is there any way to preserve the battery life of my car battery?

  1. The lifespan of your car battery depends on where you live, how frequently you drive short distances and how often you keep your gadgets plugged in.
  2. Living in an area that has warm weather year-round shortens the life of your car battery. The battery will also drain faster if you regularly drive for 20 minutes or less, as this does not allow your battery to fully charge. Try your best to keep these short trips to a minimum.
  3. Avoid overusing your gadgets when your car is not running. Using the horn, stereo, headlights or other accessories when your car is off can actually drain your battery life a lot faster.
  4. Make sure all of the car doors are closed and the lights go off after you park your car.

How do I know if my car battery is dying?

Sign 1: Engine cranks but weakly
Sign 2: No crank, no start, and no lights
Sign 3: One day it starts fine, the next day it won’t
Sign 4: Cold cranking is hard work
Sign 5: You’ve jumped it a lot

In-Car Gadgets and Devices

If possible, always avoid using the horn, stereo, headlights or other accessories when your car is off as it is drawing power directly form the car’s battery.

Prolong usage will deplete the battery and shorten the battery’s lifespan.

HELP! My car is unable to start!

DO engage the professionals for help.

DO NOT attempt to do the following as you may damage your car, other’s car, or even worst, injure yourself:

  • Attempt a jump start yourself
  • Attempt a jump start for others
  • Force starting the car
  • Replacing the car battery yourself if you have no experience

We do have cases where our clients’ vehicles got damaged when trying to help someone or being helped by someone when both parties do not have any knowledge in car batteries and the electrical components.

Why is the battery terminal head corroded?

In case of sealed lead acid battery (also known as SLA battery or dry battery), corrosion happens when electrolyte makes its way out to battery terminals through any leaks or joints.

In case of flooded lead acid batteries (wet batteries), electrolyte can jump out while carelessly pouring water into cells. Also, fumes of sulphuric acid which is a part of electrolyte and actually responsible for corrosion keeps arising out of vents of flooded lead acid batteries when battery is charging or hot.

Overcharging heats up the battery and heat increases the volume of electrolyte filled inside it. This electrolyte can leak out of vents of overcharged flooded lead acid battery if it is topped up with too much water and also SLA batteries through loose joints. Posts of lead acid batteries are mostly made from lead.

Lead itself is a stable metal. Its reaction with sulphuric acid is very slow. If contact happens at battery posts, the compound which is formed as a result of reaction is lead sulphate.

Sometimes, it also happens that copper clamps or ringed copper terminals which are used to connect battery with wires corrode. Copper itself is not reactive even if dilute sulphuric acid is poured on it. But when electricity passes, it reacts with sulphuric acid and produce copper sulphate along with water and sulphur dioxide gas.

The white substance which you see around battery terminals is either lead sulphate or anhydrous copper sulphate. Anhydrous copper sulphate changes to blue colour when water is added to it. The bluish substance which you see around corroded copper terminals or copper clamps is hydrated copper sulphate.
