The Comparison of Flooded, Gelled and Immobilized Lead-Acid Batteries

The maintenance free battery has received wide acceptance in a number of applications in recent years. Very recently, large power, maintenance-free batteries have been developed which can be employed in telecommunications applications. Maintenance-free batteries offer advantages in reduction of maintenance and venting requirements and avoid spillage during transit with minimal loss in electric performance. Life performance data on the large power batteries is not yet available although this product has been designed with the same lead components used in 20-year flooded batteries.
