Three hose timers put into service four months ago. Now on their third set of Duracell alkaline batteries. Temperature here never goes below 40, and the timers operate once every 10 days.
Has anyone replaced their battery-eating timers and gotten normal battery life?
Edit: Regarding distance from hub to timers: My hub is one floor below the timers in a wood frame building, 35’ away from two of them and 15’ away from the other.
