What is the difference between AGM and EFB batteries?

[CollinLee]

AGM batteries are ultra-fine glass fiber batteries, while EFB batteries are start-stop batteries. The structure of AGM batteries is different from ordinary batteries, offering better performance and a longer lifespan. However, AGM batteries are sensitive to high temperatures, making them suitable for placement in the trunk, whereas EFB batteries are better suited for the engine compartment. Here is some relevant information about batteries: 1. Battery function: Batteries are a crucial component in a car. Without a battery, the engine cannot start. When the engine is not running, the battery supplies power to all electrical devices in the vehicle and is also responsible for starting the engine. During engine startup, the starter motor, fuel supply system, and ignition system all require electrical power. 2. Extending battery life: Maintaining proper driving habits can effectively extend the battery's lifespan. It is recommended not to use electronic devices in the car for extended periods when the engine is off. During engine startup, avoid turning on power-intensive devices such as the air conditioner and headlights. In winter, try to park in a garage or underground parking lot to protect the battery.
