The most common battery for marine, RV and solar applications is the lead acid battery. These batteries are not sealed and have to be kept in a vented area as fumes can occur during charging. This type of battery also requires maintenance of fluids in the battery.
Absorbed Glass Matte (AGM) batteries are the latest and greatest in lead-acid batteries. An AGM battery uses a separator consisting of fiberglass between the plate and wrappers to hold the electrolyte in its place with capillary action. Due to the tight packing of an AGM battery, it is also the most impact resistant, and boasts the least internal resistance. The lower internal resistance increases the output voltage and decreases charging time. AGM batteries then bring the trump card to the table; they are maintenance free. No acid leaks, no mess while charging, no corrosionon surrounding parts. You plug in these batteries and walk away and no maintenance.
