These are the best lead-acid type battery for most Ham Radio use. They are sealed, won't leak, and can both deliver and charge at higher rates compared to Gel and Flooded batteries.
They are vibration resistant, can operate in any position, and are VRLA (Valve Regulated Lead Acid). They operate by quickly recombining the gases into water, so they don't outgass or lose water in normal operation.
AGM are good for solar systems because they capture more of the charge energy, up to 90%. Flooded and Gel batteries may only capture 70%.
AGM are good for dry camping with RV/Generator systems because they can be charged at very high rates and capture up to 90% of the charge energy. This is much faster and more efficient than flooded or gel batteries.
