Sealed AGM Batteries
AGM (absorbed glass mat) batteries are a sealed-cell variety of lead acid batteries. They're sealed because they don't require watering, making them appropriate for intermittent off-grid solar use like backup power systems or vacation cabins, and opening them up for more mounting options for added convenience.
While AGM batteries' cycle life is shorter than gel cell batteries (the other sealed lead-acid format), they're also less expensive.
