Why do Discover VRLA DRY CELL AGM and GEL batteries have excellent shelf life?

Why do Discover VRLA DRY CELL AGM and GEL batteries have excellent shelf life?

Discover uses higher quality superior grids, premium separators and pure electrolytes, which make the difference in preventing high self-discharge rates. Impurities in the lead alloy, separators and electrolyte cause tiny currents inside a cell, which eventually discharge the battery and shorten its shelf life.

Premium inter-cell welds block the slight cell-to-cell currents that cause self-discharge.
