Thanks for the reply. Is Swimpure part of Hayward?The Hayward T-Cell-15 and Hayward T-Cell-15-SWP are the same thing.
The T-Cell-15 has a 3 year warranty.
The Hayward T-Cell-15-SWP is a Swimpure branded cell, which has a 2 or 3 year warranty. You would need to verify with the seller to be sure.
The first number of the serial number is the length of warranty.
The TCELL940 is a T-15 "long life" cell with a 4 year warranty.
A T-15-W is a warranty replacement cell with a 1 year warranty. It's not designated as a retail cell. It's supposed to be used as a replacement for a cell that fails under warranty. Some places sell warranty cells as regular cells.

The mismatched serial numbers sounds suspicious. From whom did you buy?On my new one, the label on the box show W3T-cell-15 but the actual unit labeled as T-cell-15. Serial numbers on the box’s label matcheswith the one on the actual unit and starts with 1E. From what I understand, W3 sku (open line) is for online sale with 1 yr warranty where one without the W3 is from pool store with 3 yrs. With that said, am confused as which one I just got.
Oops, I misread your post. Thank you for clarifying.The serial numbers match. The model numbers are different. On the box, W3T-CELL-15 and on the unit, T-CELL-15. Sorry for the confusion. My point was if it’s possible for a T-CELL-15 to have a serial number starts with 1E which is a one year warranty.
