  Test a new set of alkaline batteries. Write down the date of installation and the voltage of the 

batteries. 

  When the batteries fail, please note the date and voltage again.  

  Check the 

distance 

and 

resistance

 between the outdoor sensor and weather station. Outdoor sensors 

at the end of the range may work while batteries are fresh but not after they drain a bit. 

  Check for leaking batteries, which may damage the outdoor sensor. 

  Battery life is over 24 months when using reputable battery brands for both Alkaline and Lithium 

batteries.
