aqua-rite cell voltage

My Aqua-Rite cell voltage is a little high when generating, it is reading 26.6 while the manual says that the typical voltage is 22.0 to 25.0 volts.
Any idea what would cause this and should I be concerned about it?

I thought the range was ~ 22 - 27 volts, if I remember correctly so I think you're fine. I would look to the salt level, temp or cell clogged for an explanation or the cell age (I believe older cells draw more volts, this can be partially offset by raising the salt level on an older unit).

I'm doing this out of memory (my wife has been cleaning/ organizing again - so I can't lay hands on my notes :mad: )

I don't think it's a big deal right now, but keep an eye on it.

Thanks for the reply. Yes the water is cold, around 53 degrees and the system is going on 4 years old.
