Sealed Deep Cycle Lead Acid AGM 12V Battery, is use in solar panel power application for storage and backup. Has a longer life cycle comapred to flooded battery. Designed with a 30% discharge and has a cycle life of 2 to 3 years.

The lead acid battery is the oldest type of rechargeable battery. Despite having a very low energy-to-weight ratio and a low energy-to-volume ratio, its ability to supply high surge currents means that the cells have a relatively large power-to-weight ratio. These features, along with their low cost, makes it attractive to continue to dominate the solar market.

As they are inexpensive compared to newer technologies, lead acid batteries are widely used even when surge current is not important and other designs could provide higher energy densities. Large-format lead acid designs are widely used for storage in backup power supplies in cell phone towers, high-availability settings like hospitals, and stand-alone power systems. For these roles, modified versions of the standard cell may be used to improve storage times and reduce maintenance requirements. AGM absorbed glass-mat batteries are common in these roles, collectively known as VRLA (valve-regulated lead-acid) batteries.
