There are several types of car batteries available, each with its unique characteristics and advantages. The most common types are:
- Lead-Acid Batteries: These are the most widely used type of car battery, accounting for over 90% of the market. They are relatively inexpensive and reliable, but may not provide the same level of performance as other types.
- Absorbed Glass Mat (AGM) Batteries: These batteries use a special glass mat to separate the lead plates and electrolyte, making them more reliable and durable than traditional lead-acid batteries.
- Enhanced Flooded Battery (EFB) Batteries: These batteries are similar to AGM batteries but use a different type of separator to improve performance and durability.
- Lithium-Ion Batteries: These batteries are increasingly popular in modern vehicles, offering improved performance, longer lifespan, and reduced weight.
Each type of battery has its unique characteristics, such as:
Capacity: Measured in Ah (Ampere-hours), it represents the amount of energy the battery can store and release.
Reserve Capacity: Measured in minutes, it represents the amount of time the battery can provide a minimum cranking current after being fully discharged.
Cold Cranking Amperage (CCA): Measured in amps, it represents the battery’s ability to provide a high current at low temperatures.
Battery Maintenance and Testing
Regular maintenance and testing are crucial to ensure your car battery remains in good condition and lasts as long as possible. Here are some tips to keep in mind: (See Also: How Long to Charge a Car Battery Jump Start? – Safe Restart Procedures)
