No store we check sells it online; the maker lists where to buy or who installs it.
Pros
- Drop-in replacement for an IC20 cell on an existing IntelliChlor power center
- Shows the salt level in ppm and shuts off in cold water on its own
- Certified to NSF/ANSI 50 and works with Pentair automation and app
Cons
- Needs the PC100 power center, sold separately online (about $450)
- LT warranty is 2 years or 6,000 hours, shorter than the Plus models
- Bought online, Pentair’s warranty shrinks to a short parts-only cover

| Warranty and models | |
| Warranty | 2 years |
| Warranty terms | TradeGrade product: 2 years or 6,000 operating hours, whichever comes first, when bought from and installed by a pool professional (LT cells). Pentair's warranty page gives TradeGrade products bought online a much shorter limited warranty (60 days on the product page; 1 year, parts only, on the warranty page), so DIY online buyers get far less cover. |
