Compared to other conventional battery systems, lead-acid batteries (LABs) are often overlooked and viewed as an outdated technology with minimal technical potential. Nonetheless, research on LABs have continued from the viewpoint of new features, reliability, and fuel and cost savings, including developments of absorbent glass materials [ [1], [2], [3] ],
A lead acid battery consists of a negative electrode made of spongy or porous lead. The lead is porous to facilitate the formation and dissolution of lead. The positive electrode consists of lead oxide. Both electrodes are immersed in a electrolytic solution of sulfuric acid and water. In case the electrodes come into contact with each other through physical movement of the battery or
AGM batteries are lead-acid batteries that are sealed, non-spillable and maintenance-free. They use very fine fiberglass mats between thicker lead plates to trap the electrolyte. They''re generally more robust than FLAs, but the causes of premature failure are similar. The most common culprits include: Improper charging (overcharging or undercharging)
