When most people think of AGM batteries, they probably think of deep cycle battery applications. However, not all AGM batteries are deep cycled. While a popular choice for deep cycling, because AGM batteries have a depth of discharge (DoD) of 80% compared to 50% DoD for standard flooded batteries, it is also a popular choice for starter batteries. This is because it has low internal resistance and can quickly supply large current loads. AGM batteries are also used as start-stop batteries in modern cars because the flooded batteries are not strong enough. Can't handle repeated loops in start-stop apps. This can cause the battery to fail after only a few years of use.

    Each cell in an AGM battery has 2 volts, so AGM batteries are available in a variety of voltages, including the popular 6V and 12V models.

    AGM technology has many benefits over its older flooded battery structure. One of the great things about fiberglass mats is that since the mats contain acid, the batteries are less likely to be sulfated. This feature allows it to reach deeper mods than submerged equivalents.

    The lower internal resistance of AGM batteries also has a lower self-discharge rate, so top-charging is not required as frequently as a water-filled battery under long-term storage conditions. It is important to note that AGM batteries must still be charged prior to storage, and maintenance charging will be required during long-term storage but will charge faster than fully charged batteries.

    Some advantages of AGM over flooded batteries (and faster charging) are increased cycle life and vibration resistance. That's because the combination of the tightly packed AGM battery and internal pad acts as a damper, features ideal for powering sports applications. Another benefit of the pad is that the battery requires less electrolyte than a submerged battery, which saves weight.

    However, one of the downsides of an AGM battery is its cost - slightly more than a flooded battery, you'll pay more for a battery that doesn't require the same maintenance as a flooded battery.
