Nearly all users prefer purchasing a dual-purpose AGM battery as it has an ideal blend of starting and deep cycle types, being packed of power but still sustain deep recharge and discharge cycles of the batteries. Nonetheless, due to the diversity of functions it has, it would require more investment to be purchased.

  • Primary Types of AGM Battery

The latest AGM batteries types are based on its basic functionalities, which means that the AGM battery types is related with the vehicle for which it is meant to be used for such as golf cart, solar store, recreations, bikes car or marine. Let’s get to the point, RV AGM designs are utilized for leisure vehicles and have high CCA and deep cycle batteries are used for more reserve capacity. While the AGM marine battery needs high CA and MCA rating to turn on, the engines motorcycle AGM battery is apt for motorcycles which helps it function for a long time without charging. The AGM batteries for solar storage are joined through wires with the help of a converter in the solar panel. Car AGM battery or automotive batteries are quite bigger in size to generate high power burst or CCA.

  • AGM Battery Plates

The AGM battery plates should be thick like the life duration of the batteries, as it right away puts an impact on the electrolyte and warped around the glass mates. So, one should check the thickness of the plates prior to purchasing the battery. The latest AGM batteries are absolutely vibration proof as this increases the reserve capacity and deliver the best performance like never before. Also, a shock resistant battery can easily prevent the battery damages and battery dead situation.

  • Productivity and Inner Resistance

Usually, an excellent AGM battery should generate high currents with no major or upsetting voltage falls. The inner resistance of this type of battery is as low as 1 to 2 %, protecting AGM battery from warming up speedily and not getting affected by the thermal runaway which is damaging for your battery.
