They look like AGM batteries. Is your charger set for AGM?

How can I find that out? If it isn’t, how can I fix that?

Original Gem chargers do not have an agm setting.  
From what others on here say, AGMs only last about 9 months if not charged correctly.

Can the Gem charging system be programmed to correctly charge AGM batteries?
