General Questions
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.
