  * A fresh battery typically has a voltage ranging from 2.8 to 3.1V (also depends on temperature). The battery discharge rate is fairly flat but once it is discharged it can decay rapidly. Note that when the board is powered, the 3.3V power supply supplies power to the GSC and the battery will not be drained. This should be factored in when determining battery lifetime.

 When a board is powered on, the GSC will draw power from the primary power supply and not it's coincell battery.

 Care should be taken that the board is stored in a way that the battery case (which is the + side of the battery) does not come in contact with a conductive path to ground on the board as doing so would not only drain the battery but if this conduction path persists for ~8 seconds or more it would put the GSC into 'reset' where its current path (even after the battery short is removed) is higher than normal. This is the same scenario described above in the Battery replacement section and can be resolved by powering the board on at least once to get the GSC out of reset.
