Types of Car Batteries
There are several types of car batteries available, each with its own unique characteristics and advantages. The most common types are:
| Type | Description |
|---|---|
| Flooded Battery | A traditional lead-acid battery with liquid electrolyte, requiring regular maintenance and topping off. |
| Sealed Battery | A maintenance-free battery with a sealed casing, eliminating the need for topping off or maintenance. |
| Enhanced Flooded Battery (EFB) | A hybrid of flooded and sealed batteries, offering improved performance and durability. |
| Absorbed Glass Mat (AGM) Battery | A high-performance battery with a special glass mat that absorbs the electrolyte, providing improved starting power and durability. |
| Start-Stop Battery | A specialized battery designed for vehicles equipped with start-stop technology, which shuts off the engine during idle periods to conserve fuel. |
| Deep Cycle Battery | A battery designed for heavy-duty applications, such as RVs and boats, which requires deep discharging and recharging. |
Capacity and Size
Car batteries come in a range of capacities, measured in Ah (Ampere-hours) or CCA (Cold Cranking Amps). The most common capacities are:
- 40 Ah: Suitable for small cars and motorcycles
- 60 Ah: Suitable for mid-size cars and SUVs
- 80 Ah: Suitable for larger cars and trucks
- 100 Ah: Suitable for high-performance vehicles and heavy-duty applications
The size of a car battery is typically measured in inches, with the most common sizes being:
- Group 24: Suitable for small cars and motorcycles
- Group 27: Suitable for mid-size cars and SUVs
- Group 31: Suitable for larger cars and trucks
