The battery is the main source in the car’s electrical system. In Indonesia itself, several types of car batteries are commonly used. The following is a brief explanation of the types of car batteries that are often encountered:

1. Maintenance-Free (Dry) Battery

Maintenance-free (dry) batteries do not require additional maintenance, such as the addition of water. The electrolyte fluid in this type of MF battery contains calcium, which means it has a relatively lower evaporation rate. It is suitable for those with high mobility but limited time for maintenance, as this type of battery simplifies car maintenance for owners. Additionally, this MF battery type is equipped with “Sealed” technology that reduces the risk of battery water spillage due to shocks, thus minimizing corrosion on the vehicle.

2. Wet Cell Battery

Wet cell batteries are a type of car battery that requires periodic water addition. These batteries are more economical but require extra attention in maintenance. Users must monitor and adjust the electrolyte water level to maintain chemical balance in the battery. Wet cell batteries are commonly used in conventional cars and require regular maintenance to ensure optimal performance. This battery type is a starter battery, designed specifically to meet the high electrical supply needs for starting a car.

3. Absorbent Glass Mat (AGM) Battery

AGM (Absorbent Glass Mat) batteries are a type of car battery that uses a glass mat separator to absorb the electrolyte. Its design makes it resistant to vibrations, ideal for cars with advanced features such as start-stop systems. AGM batteries are usually more expensive but offer good performance and a long lifespan. They are suitable for use in modern vehicles with high electrical demands.

4. Gel Battery

Gel batteries are a type of car battery that uses electrolyte gel as the conductive medium. Similar to MF batteries, gel batteries are resistant to position changes and vibrations, making them suitable for off-road vehicles or those frequently exposed to vibrations. Although more expensive, gel batteries are known for their reliability and ability to operate in extreme conditions.

5. Calcium (Ca-Ca) Battery

Calcium, or Ca-Ca (Calcium-Calcium), batteries are a type of car battery that contains calcium in its grids. Calcium increases the battery’s resistance to corrosion. Calcium batteries are commonly used in vehicles in areas with high ambient temperatures. Their main advantage is better corrosion resistance, making them a good choice for hot conditions.

6. Hybrid Battery

Hybrid batteries are specially designed for use in hybrid vehicles, which combine an internal combustion engine with an electric motor. These batteries are typically designed to handle the additional electrical load from the electric motor and support features like energy regeneration during braking. Hybrid batteries can provide power for the car when running on an electric engine or work in conjunction with the internal combustion engine. Their design can vary depending on the specific model and manufacturer of the hybrid vehicle.

When selecting a car battery type, it’s best to match it to the vehicle’s needs and the user’s preferences. Be sure to check the battery and car manufacturer’s recommended usage and maintenance instructions.
