The remaining battery life can be estimated from the battery life indicator shown on the display. The NODE can operate using either a single 9-volt battery or using two 9-volt batteries. Using two nine volt batteries will yield approximately twice the battery life of a single 9-volt battery. The battery life indicator chart below shows an estimate on the remaining battery life.
Full: 100–60% remaining battery life
Med: 60–25% remaining battery life
Low: 25–0% remaining battery life
Replace battery immediately!
From a battery life standpoint, the answer is not as easy as saying "the batteries will last for two years". The answer really depends upon the number of actuations that the controller operates over a given period of time. The chart below provides the maximum on/off actuations based upon the period of operation. If you want the batteries to last one year, the maximum number of on/off actuations is 7,300.
