This year when I started up my pool which uses the Zodiac Duoclear 130 chlorinator system I noticed the Chlorinator settings were not being saved when turning off the power to the system. I intend on getting a timer for my pool but in the meantime I’ve been turning the power off weekday mornings and turning it back on late afternoon.

This weekend I finally took the control cover apart to find the “long-life rechargeable battery” is a ML2032 button cell which has leaked.
