A: These cells have the same performance, size, fittings, and cord connections. They are just produced by another manufacturer, who also handles the warranty. Additionally, this cell is clear, so you can see it working and inspect it without taking it apart.

Q: What is the typical life span?

Asked by: Deadeye - 5/4/2020
A: It depends on your pool size and how you use it. But its made to the same specs, so it should last just as long. I would estimate average 2-5 years across the board.

Q: Will this cell fit the 66120rc? I see this question has been ask before but not a clear enough yes that I would order it. A yes is what I would prefer.

Asked by: Ernie - 8/8/2019
A: Ernie, this cell is only marked to be compatible with any cell labelled T-15 or T-Cell-15. Upon doing a little research, unfortunately the model you are referring to appears to be an unknown overseas manufacturer and there is a fair chance it will only work with its own labelled products.

Asked by: dennis - 1/30/2020
A: Yes, if you currently have a cell marked "T-Cell-15", than any of the T15 cells on our site will be compatible. There are options with shorter and longer warranties.
