We offer cells that are aftermarket replacements for T-9 and T-15 cells. You would want to check which cell types are available on your control center (page 8 in the aquarite manual https://www.hayward-pool.com/assets/documents/pools/pdf/manuals/aquarite-aqr-owners-manual.pdf). If you have the T-9 or T-15 cell type setting, either should work and be an upgrade in capacity, which is typically a good thing.
