What does AGM on a battery mean?

[Jon]

Automotive AGM battery is a valve-regulated sealed battery that uses glass fiber separators. Automotive battery, also known as storage battery, works by converting chemical energy into electrical energy. The application models of AGM batteries and maintenance methods for automotive batteries are as follows: Application models of AGM batteries: Most AGM batteries are used in cars with automatic start-stop systems. AGM batteries have superior cycle performance and charging acceptance compared to traditional lead-acid batteries. They perform better than lead-acid batteries in low-charge states and have a longer service life than most lead-acid batteries. Most AGM batteries can last 7 to 8 years without any problems. These batteries are suitable for cars equipped with engine start-stop technology and also meet the requirements for cars with more electronic systems. Automotive battery maintenance methods: Avoid parking the car in open parking lots for extended periods to prevent the battery from freezing and getting damaged; car engines are harder to start in winter, and each start attempt should not exceed 5 seconds, with an interval of at least 15 seconds between attempts.
