My 9V battery keeps dying, what does that mean?

When Irritrol RainDial batteries keep draining faster than they should (usually they last at least a year or more), it is a sign that the controller is failing, but has not failed completely.

As the parts fail they can degrade slowly and the battery ends up providing power to compensate.  However, this causes the battery to drain faster, meaning it may last a week, or month instead of a year.  Eventually you’ll have to replace it more and more frequently until even a new battery won’t be enough for it to work.

There’s no way to really predict when a new battery will not be enough to make it work. One thing is for sure: “you’re living on borrowed time.”

You can wait if you want, but it’s usually better to get it taken care now, otherwise Murphy’s law usually kicks in and it’ll fail right before you are headed out on a long vacation 🙂   They often are intermittent as they’re failing, so it will not water, but when you notice the dying plants, but when you test it, it’ll seem to be working.  When it’s “on the edge of complete failure” it sometimes works, and other times not.  The temperature often effects the behavior.

Irritrol RainDial timers are well made an with a quick repair can last another 10 years. Repairs are the core of our business and we’d appreciate it if you’d select us to do the it.

  1. You can always water manually by turning on the valves at the valve box, but since you’re close, I’d just swing by my place this weekend and run some errands while I repair it. I’ll followup with an email.

    Thanks,

  2. Hate to do without it for any time as we live in Scottsdale, AZ. Let me know how much to repair and how long it would take. We are not planning being gone for any length of time. Should I consider purchasing a new controller?
    Where are you located?
