Flooded lead-acid batteries are the most cost-effective option but require regular maintenance, while sealed lead-acid batteries (AGM and gel) are more expensive but do not require regular maintenance.

    AGM batteries are vibration resistant and can handle higher charge/discharge rates, while gel batteries can withstand high temperatures and work best with slow, deep discharges.

    Sealed lead-acid batteries are very similar to submerged batteries, but do not have access to the internal compartment. This means you don't have to add distilled water. The electrolyte is sealed inside, and there is enough volume to allow the battery to complete the calculated number of cycles.

    Absorbent glass mat batteries are the most popular VRLA batteries because they can work in a variety of conditions. The electrolyte is suspended in thin fiberglass mats located between lead plates. This makes the batteries resistant to vibration, which makes them a great choice for RVs and other mobile applications.

    They can also be mounted in any orientation. It is common to see them mounted on the side for easy placement and wiring.

    AGM batteries are more expensive than submerged lead-acid batteries and don't last as long. But for that extra price, you don't have to maintain the battery or deal with as much gas released during the charging phase.

    They are ideal for mobile applications, where acid leaks, remote areas where regular maintenance is not possible, and where batteries can be exposed to extremely cold temperatures.
