Salt Cell Life Remaining Calculator

Estimate the remaining service hours and months of your chlorinator cell before replacement is required.

Quick Conclusion
Most salt chlorinator cells are rated for 8,000 to 10,000 hours of operational life. For an average pool season, this equates to 3 to 5 years of service before the ruthenium coating depletes and the cell requires replacement.

Technical Comparison

Cell Model Rated Hours Avg Lifespan (Years)
T-Cell 15 (40k Gallon) 10,000 hrs 4 - 6 Years
T-Cell 9 (25k Gallon) 8,000 hrs 3 - 5 Years
T-Cell 3 (15k Gallon) 5,000 hrs 2 - 3 Years

Actionable Steps

Pro-Tip

The "Reverse Polarity" Secret: Modern salt systems reverse current flow every few hours to shed calcium scale automatically. To maximize life, use a Variable Speed pump at low RPM; this allows the cell to produce chlorine steadily for 24 hours at a low output percentage (e.g., 20%) rather than 100% output for 4 hours, which is much "healthier" for the plates.

Frequently Asked Questions

What kills cells?

High calcium, frequent acid washing, and running at 100% output constantly.
