780 Ampere-hours per kilogram (Ah/kg) Consumption Rate: Approximately 11.2 kg per Ampere-year Efficiency: 95% or higher Installation and Maintenance Best Practices Replace the zinc anode 620 when: | Parameter
A 620 anode should be replaced when it has diminished to roughly 50% of its original size. Once it passes this point, the surface area is often too small to provide the required current density to protect the surrounding metal. Environmental Considerations These numbers tell an engineer exactly how much
Moving past the chemistry, the will list the electrochemical properties. These numbers tell an engineer exactly how much protection they are getting for their money.
The datasheet for a 620 anode isn't just about size; it's about energy capacity.
