Définition du message (Fonctionnement, entretien et régénération de batteries au plomb)
Les batteries AGM sont un type de batterie étanche / VRLA. Dans une batterie AGM, l'électrolyte est liquide mais maintenu en place dans un buvard en fibre de verre, d'où son nom: Absorbed Glass Material.

!Avantages
!Inconvénients
|-
|Sans entretien avec un faible dégagement gazeux
|Ne supporte pas la chaleur (perte de l'électrolyte sous forme de gaz - effet définitif)
|-
|Bon maintient de l'homogénéité de l'électrolyte
|Ne supporte pas les surcharges (perte de l'électrolyte sous forme de gaz - effet définitif)
|-
|Supporte bien le froid car électrolyte homogène
|Durée de vie limitée (taux d'acidité obligatoirement élevé)
|-
|Permet de faire passer des courants de crête forts (CCA)
|
|-
|Résiste bien aux chocs car tout est bien maintenu à l'intérieur
|
|-
|Faible autodécharge (1-3% par mois)

!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)
| They have limited shelf-life. (as the acid concentration inside is higher than in others, which leads to faster battery degradation). ) 
|-
|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)
