General Questions: Battery
A car battery provides the electrical energy needed to start your engine and powers electrical components when the engine is off.
On average, a car battery lasts 1 to 3 years, depending on usage, climate, and maintenance.
- Slow engine crank
- Dim headlights or electrical issues
- Clicking sound when turning the key
- Dashboard battery warning light
Check your owner’s manual or consult a professional to match the correct size, capacity (Ah), and Cold Cranking Amps (CCA) for your vehicle.
- MF (Maintenance-Free): Sealed, no water refilling needed.
- EFB (Enhanced Flooded Battery): Better for vehicles with Start-Stop technology.
- AGM (Absorbent Glass Mat): High-performance, deep cycle, and best for modern cars with advanced electronics.
Battery Maintenance & Usage
- Avoid frequent short trips
- Ensure the battery terminals are clean
- Check and maintain proper charging voltage
- Avoid leaving electronics on when the engine is off
Yes, but you should follow the correct procedure:
- Remove the negative (-) terminal first
- Then remove the positive (+) terminal
- Install the new battery in reverse order, positive (+) terminal then negative (-) terminal.
Most new car batteries are pre-charged and ready to use. However, it’s good to check the voltage (should be around 12.6V).
At least every 6 months or during routine servicing.
- Leaving lights or electronics on
- Faulty alternator or charging system
- Extreme temperatures
- Short, frequent trips without sufficient charging
Battery Charging & Jump-Starting
- Connect the red (+) cable to the positive terminal of the dead battery.
- Connect the other end of the red (+) cable to the positive terminal of the working battery.
- Connect the black (-) cable to the negative terminal of the working battery.
- Connect the other end of the black (-) cable to an unpainted metal surface on the dead car.
- Start the working car, wait a few minutes, then try starting the dead car.
It depends. If the battery voltage is too low (below 10V) or if it has internal damage, it may need replacement.
- With an alternator (driving the car): About 30 minutes to an hour for a partial charge.
- With a battery charger: 4 to 12 hours depending on the charger’s amperage.
No. Use a compatible charger for your battery type (Lead Acid, EFB, AGM).
Yes, but it’s not efficient. Driving at moderate speeds is better for charging.
Battery Issues & Troubleshooting
Possible reasons:
- Parasitic drain (electronics drawing power when off)
- Weak alternator (not charging properly)
- Old battery (needs replacement)
Do not use it! A swollen battery is dangerous and needs to be replaced immediately.
Yes, a failing alternator can cause undercharging (weak battery) or overcharging (damage).
- Mix baking soda with water
- Use a wire brush to clean corrosion
- Apply petroleum jelly or battery terminal protector to prevent future corrosion
Cold temperatures reduce battery efficiency, making it harder to start the engine. Consider a battery with a higher Cold Cranking Amps (CCA) rating.
Buying & Warranty Questions
Check the purchase receipt and the battery’s warranty period.
- Low capacity: May not start the car reliably.
- Wrong type: Could damage electrical systems.
Cheaper batteries may have lower lifespan and performance. Investing in a high-quality battery saves money in the long run.
It indicates how much charge the battery can store and deliver over time.
No, they use a high-voltage battery system, but many hybrids still have a small 12V battery for accessories.
Miscellaneous Questions
Not recommended. Deep-cycle batteries are better suited for solar applications.
An MF battery is sealed and does not require water refilling.
Yes, but keep it charged and store it in a cool, dry place but it is not recommended as the battery lifespan will drop over time.
Yes, but ensure it’s secured upright to prevent leaks or damage.
Take it to a battery recycling center or an auto shop that accepts old batteries.
General Questions: Lubricant
Lubricant is a substance that reduces friction between moving parts in an engine or machinery. It helps prevent wear, dissipates heat, cleans, and protects components from corrosion.
There are four main types:
- Engine oil (for combustion engines)
- Transmission fluid (for gearboxes and automatic transmissions)
- Grease (for high-friction areas)
- Industrial lubricants (for manufacturing equipment)
Always refer to your vehicle’s manual for the recommended oil viscosity (e.g., 5W-30) and API/ACEA specifications. You can also consult with a trusted mechanic or supplier.
- Mineral oil: Derived from crude oil, less refined, and cheaper.
- Synthetic oil: Engineered for better performance, longer life, and higher resistance to extreme temperatures.
The numbers represent the oil’s thickness and flow at different temperatures.
- The first number (5W) refers to the oil’s viscosity in cold conditions (Winter).
- The second number (30) indicates how thick the oil remains at operating temperature.
It depends on the oil type and driving conditions:
- Mineral oil: Every 5,000 km
- Semi-synthetic oil: Every 7,000 km
- Fully synthetic oil: Every 10,000 km
Mixing oils can alter performance and may void warranties. It’s best to stick with the recommended oil type and brand.
Using incorrect oil can lead to increased engine wear, overheating, poor fuel economy, and even engine failure.
- Better high-temperature stability
- Longer oil change intervals
- Improved fuel economy
- Superior engine protection
- Park on a level surface and turn off the engine.
- Wait at least 5 minutes for the oil to settle.
- Pull out the dipstick, wipe it clean, insert it back, then remove again to check the level.
Lubricant Performance & Specifications
- API (American Petroleum Institute): Sets oil quality standards (e.g., API SN, API SP).
- ACEA (European Automobile Manufacturers’ Association): Defines performance for European vehicles.
- OEM Approvals: Vehicle manufacturers like BMW, Mercedes, and Honda have their own oil specifications.
High-quality oil reduces friction, keeping the engine clean and running smoothly. This improves fuel efficiency and performance.
- Petrol oil: Designed for gasoline engines, contains fewer detergents.
- Diesel oil: Contains higher detergency to manage soot and carbon buildup
- Black oil means it is cleaning carbon deposits and dirt.
- If it thickens or forms sludge, an oil change is needed.
- Contains additives to reduce oil leaks
- Enhances engine sealing
- Provides extra wear protection
Unopened, it lasts up to 5 years. Opened bottles should be used within 6-12 months.
Yes, quality oil provides better protection against wear and sludge buildup, extending engine life.
Low-friction synthetic oils reduce drag inside the engine, leading to better fuel efficiency.
It forms a protective film between metal parts, preventing direct contact and reducing friction.
- Oil additives improve lubrication, cleaning, and engine protection.
- Most high-quality oils already contain necessary additives, so extra additives may not be needed.
Lubricant Troubleshooting & Issues
- Worn piston rings or valve seals
- Engine overheating
- Using the wrong oil type
- Sludge forms due to heat, oxidation, and infrequent oil changes.
- Use high-quality synthetic oil and follow regular oil change schedules.
Drain excess oil immediately. Overfilling can cause foaming and engine damage.
Yes, but ensure the engine is clean and in good condition before switching.
- Low oil level or incorrect viscosity
- Engine wear or a failing component
- Dark, dirty oil
- Increased engine noise
- Decreased fuel efficiency
Yes, oil helps cool the engine by reducing friction. Poor-quality or old oil can lead to overheating.
Take it to a certified recycling center or auto shop. Never dump oil in the environment.
- Driving conditions (stop-and-go traffic vs. highway driving)
- Engine design and oil type used
- Increased engine wear
- Sludge buildup
- Risk of complete engine failure
General Questions: Windscreen Wipers
