The CaliMar® CMARCHA40-2Y salt cell is a generic replacement for the Hayward T-CELL-15, meant for use in Hayward Goldline AquaRite, Aqua Logic and Pro Logic salt systems. CaliMar® replacement cells are proven to provide reliable performance after being tested under rigorous conditions. We are proud to offer these products to our customers as a more economical alternative to OEM (original equipment manufacturer) models and other generics.
If your Hayward salt system was built prior to 2009 you can use an OEM factory T-CELL-15 or generic equivalent like this replacement cell. Replacement salt cell CMARCHA40-2Y is compatible with Hayward systems made before 2009. If any of the following applies to you, the CaliMar® CMARCHA40-2Y replacement salt cell is the proper generic replacement cell choice for your Hayward salt system:
  • Your system was made prior to 2009 
  • Your pool is larger than 25,000 gallons in volume 
  • You are replacing a T-CELL-15 salt cell
The CMARCHA40-2Y is a plug-and-play unit, meaning it fits perfectly with existing plumbing and Hayward equipment, replacing the T-CELL-15 seamlessly with no additional installation or plumbing required. It is designed to chlorinate pools up to 45,000 gallons in volume. It comes with a 15-foot cord, providing flexibility in connecting to your existing power center.

Is there a release version that is needed for this Cell T-15?
Chuck w on Apr 27, 2016
BEST ANSWER: I am Not sure what "release version" refers to, however I bought and replaced my 6 year old "Hayward T-cell-15" with this product (Calimar CMARCHA40-2Y) and it has performed perfectly for the last 2 month of our swimming season in 2015) I did remove the new cell and replace with the old cell for storage only, during winter month here in Michigan. My pool advisor encouraged me to do this so the new cell was not laying dormant in old water, all winter.

What is the difference between 2Y and 3Y?
A shopper on Feb 22, 2016
BEST ANSWER: I bought the 3 y hoping it would last longer than the Aqualogic brands that I have had over 10 years. I bought the 3y over 2y for peace of mind and hope the company will stand behind the product, which in fact seems to be the case so far! Love it this far.

good economic solution
the item arrived quickly. easy to install. plugged in and it worked great. good replacement for T-15 cell. note it can take several hours to a day for all the display data to reset, but the next day it was spot-on. my old cell was saying 700 salt level when I knew from testing it was about 2800. after 24 hrs this gave a level that perfectly matched the measurement at the pool store

Install it yourself, don't let anyone else do it!!
So far so good. I had a bigger problem with installation.
I had to remove the unit for cleaning. When I went to remove it, apparently the technician that installed it forgot it was plastic and torqued it so tight.
I almost broke the nut just trying to remove it. When it comes to this salt water unit...install it yourself. Tighten it only as much as you need so it don't leak.

Very satisfied
When I purchased this replacement cell I was apprehensive about not going with the OEM. That said, the cell fit perfectly, was immediately recognized by the circuit board and has functioned flawlessly for the two weeks I have had it installed.
