Galvanic Anode Life

Magnesium Zinc Aluminum
Utilization (percent) =    
Weight (lbs) =    
Current (amps) =    
Anode Life (yrs) =    

Select an anode material and utilization factor
Fill in any two fields and solve for the third.

* Energy capability is based on an efficiency of 95% for zinc, 85% for aluminum, and 50% for magnesium

Formula Used:
L =  years of life
W =  anode weight in lbs
C =  energy capability in amp-hrs per lb
I =  current output in amperes
U =  utilization factor as a decimal
8760 =  hours in 365 days
