Car Batteries: A Buyer's Guide
Choosing the Right Car Battery
The battery is the heart of your car's electrical system. A quality battery ensures reliable starting, stable power supply for all electronic devices, and long-lasting performance.
Types of Car Batteries
Traditional Lead-Acid Batteries
Lead-acid batteries are the most common and proven technology. Reliable and economical, they are ideal for cars with standard electrical equipment. They require periodic checks of the water level.
AGM (Absorbent Glass Mat) Batteries
AGM batteries are the premium choice for modern cars. Maintenance-free, they are more resistant to charge/discharge cycles and are perfect for cars with Start&Stop systems, energy recovery systems, and high electrical consumption.
EFB (Enhanced Flooded Battery) Batteries
EFB batteries represent an evolution of traditional lead-acid batteries. They offer better performance for cars with entry-level Start&Stop systems, at a lower cost than AGMs.
Gel Batteries
Gel batteries are sealed and vibration-resistant. Ideal for special vehicles, RVs, boats, and applications requiring deep discharge cycles.
How to Choose a Car Battery
To identify the correct battery for your car, check:
- Dimensions (LxWxH) - it must fit into the battery compartment
- Capacity (Ah) - expressed in Ampere-hours, indicates the available energy
- Cold Cranking Amps (CCA/EN) - crucial for starting, especially in winter
- Polarity - position of the terminals (right or left)
- Mounting Type - B13, B3, B1, etc.
- Required Technology - check if your car requires AGM or EFB
Car Batteries for Start&Stop Systems
Cars with Start&Stop systems require specific AGM or EFB batteries. These technologies withstand frequent starting cycles and ensure sufficient energy for all electronic systems even when the engine is off.
Capacity and Cold Cranking Amps
Capacity (Ah): indicates how much energy the battery can provide over time. Small cars: 40-60Ah, medium cars: 60-75Ah, large cars/diesel: 75-100Ah or more.
Cold Cranking Amps (CCA): indicates the cold starting capability. The higher the value, the better the starting in winter. Diesel engines require higher values.
Car Battery Maintenance
To prolong battery life:
- Periodically check the charge status (12.6V = full charge)
- Clean terminals of oxidation and corrosion
- Check the tightness of the clamps
- Use a battery maintainer if the car is stationary for a long time
- Avoid deep discharges (e.g., leaving lights on)
- Have the alternator checked if the battery drains frequently
When to Replace the Car Battery
Replace the battery if:
- The car struggles to start, especially in the morning
- The lights are dim when the engine is off
- The battery is more than 4-5 years old
- You notice bulging or acid leaks
- The resting voltage is below 12.4V
- The battery warning light comes on while driving
Car Battery Installation
Replacing the battery is simple:
- Turn off the engine and all electrical devices
- Disconnect the negative (-) terminal first, then the positive (+)
- Remove the securing system
- Remove the old battery
- Clean the battery compartment and terminals
- Insert the new battery
- Secure the battery with the appropriate system
- Connect the positive (+) terminal first, then the negative (-)
- Ensure the clamps are tight
Note: On some modern cars, it may be necessary to register the new battery via diagnostics to optimize charge management.
