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:
Where
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
