Introduction
Lead selenium alloys possess great conductivity, high tensile strength and great grid density. They exhibit good resistance towards corrosion thereby eliminating inter-granular corrosion. They also have stability under float charge and consistent cell voltages. The alloys have superior cycling and deep discharge performance.
The following datasheet will provide an overview of lead-selenium alloy.
