What type of batteries does the WaterGuru SENSE S2 use and how long should they last?

The WaterGuru SENSE S2 and SENSE S1 use 4 alkaline "C" cell batteries.

Alkaline C cell batteries are available everywhere, have a long shelf life and provide a constant voltage until the internal cells are used up. 

Note:  The WaterGuru SENSE ships with 4 C cell alkaline batteries that should last about 4-6 months.  These batteries do not have extended battery life as that of Duracell and Energizer alkaline batteries.

When it is time to replace your SENSE batteries, choose Duracell or Energizer alkaline batteries which will provide long battery life with steady constant voltage.  Do not use any other brand, i.e. "Green" or "Amazon" batteries which will not provide extended battery life.

As the SENSE battery strength depletes, Alerts will be displayed in the WaterGuru app:

• Battery low - This is an indication that there is 33.3% battery strength left 
• Battery very low - This is an indication that there is 16.7% or less battery strength left

Important:  If your SENSE S2 device batteries are not lasting 6 months and instead are lasting only a few weeks or a couple of months, this is not normal.  This means there may be a problem with your device, click here to submit a Support Request and we will respond.
