AGM batteries are a type of sealed/VRLA battery, in which the electrolyte is a liquid but it is held in place in a fiberglass blotter, and hence its name: Absorbed Glass Material. View the inside of an AGM battery Advantages Disadvantages Maintenance-free with minimal release of gas They do not perform well in hot conditions (loss of electrolyte in the form of gas at higher temperatures) A temperature above 49°C (120°F) is very dangerous for the battery life. They maintain the electrolyte homogeneity well. They are sensitive to overcharging and high voltages (loss of electrolyte in the form of gas) /

Withstand colder temperatures well because of their homogeneous electrolyte (Since the electrolyte is held in the glass mat separators, it won't expand when frozen like it will in a flooded battery Durée de vie limitée (taux d'acidité obligatoirement élevé)

Allows high peak currents (CCA) to pass Shock-resistant (Vibration-resistant) (Because of the fibre glass mats are woven tightly and the plates are packed tightly, making them immune to vibrations) Low self-discharge (1-3% per month)
