This part number is the same part number on a Jacuzzi cell and cheaper than buying that cell. Same warranty. I believe they are the same re-branded.
Even the cord is blue.
Will see how it works.

What is difference between Aguarite T-Cell-15 $463.47 & Calimar T-cell-15 $329?
A shopper on Oct 23, 2015
BEST ANSWER: I cannot give the technical differences. Used the HC-40G-3Y to replace the generator cell that came with the Goldline Aquarite Electronic Chlorine Generator for my 40000 gallon concrete pool. The replacement cell fit perfectly in the waterline and the electronic plug did also at the control box. There was no problem ever with the interface with the control box; it worked smoothly from the get-go to the present. Put in service May 1, 2015 and operates 10-12 hours per day, every day. So practically, it is identical.
Which direction does this get installed?
Cooky on Jul 3, 2016
BEST ANSWER: There should be an arrow on the body of the generator that points to the direction of water flow through the device. That is the arrow should point in the direction the water flows through the generator.
In Which direction should the cell be installed?
Cooky on Jun 29, 2016
BEST ANSWER: I went out to check mine expecting to see a direction arrow on the cell. I don't see one. Looking through the user manual the only direction specified is for the separate flow switch. The cell does not appear to be flow-direction dependent. Having said that, mine flows from left to right in the direction of the label text. It is installed in the pipe that leaves the bottom of the filter (output).
Aqua Rite claims the software of the Cali Mar will result in incorrect readings as it does not match up to their product. is this correct?
bill t on Dec 17, 2015
BEST ANSWER: Hello Bill. I cannot answer your question with 100% certitude. I have never trusted entirely the meter readings on the control box, even when using all Aqua-Rite gear. My pool guy (guru) suggested this path.. Salt readings are pretty accurate and I check once a month with a test kit. Temperature reading is accurate also and, after all that is a curiosity issue anyway; our bodies tell us if the water is cold or hot or like goldilocks, just right. If you have pool heaters, their thermostat will rule the day independent of the control box readings. As to the other chemical readings and ratios, I pay no attention to them. Take a water sample to a good pool supplies store and have it tested once a month and cross check with the water test strips that test for the several important ratios. There are also solution-based water tests for these ratios. I had to use that for Total Alkalinity testing when even the pool store test showed unreasonable levels.

With almost a whole summer of use, my CaliMar replacement cell has worked well and we have had several very heavy rainfalls and dry spells where the well water used to fill the pool is of very high Ph' leading to chemical changes that require remediation. Hope this helps.

BEST ANSWER: They usually ship ground and it takes up to 4 business days to receive.
Does the Cali mar Hayward t-15 replacement work on revision 1.4 ?
Ralph P on Oct 14, 2018
BEST ANSWER: Yes this cell will work for that revision.
Does this cell require 1.5 firmware on the Aqua Rite?
Wayne N on May 24, 2017
BEST ANSWER: The T-Cell-15 works on all firmware.
How can I tell which software mine has?
Andrew I on Jul 30, 2016
BEST ANSWER: You will have to hit the Diagnostic button 7 times until the revision is shown. It will say R.1.**. If it is R.1.55 or higher, you can you any cell. If it is lower, you can only use the T-15-Cell and T-15 generic replacements.
is the warranty through you or the manufacture. who would i contact if it had any problems?

Great Service
This was painless and when they sent me the confirming email they double my purchase which pointed out I had selected the wrong size cell from the options. They processed the credit and got me the right part.
Installed and working great. Also appreciate the 3 year warranty!

CaliMar Replacement Cell
I've had a Hayward salt system in my pool from day one. For the past 4 years the Hayward cells were only lasting about 1 year before giving out. The 1st cell would be covered by warranty but a year later I was buying another as the warranty didn't extend to the replacement. The CaliMar has worked fantastic from day 1 and is considerably more cost effective.
Make sure to disconnect the unit when you add salt to the pool to extend it's like. Thought that might have contributed to the first cells failure, but now think Hayward cut corners somewhere.

Perfect Replacement
Had my Hayward system since '09, my pool service guy recommended I looked for a replacement t-cell-15 online. Saved myself $150, cell works perfect on my system, I have no complaints.

T-cell replacement
I would definitely recommend this product as it does what it's supposed to do. However the socket where the cord enters has deteriorated. I'm anticipating a leak where the cord goes in at any time rendering this thing useless. Other than that it make chlorine everyday. Hope this helps...
