In theory, a 21 amp hour battery draining at the rate of 0.103 amps would last 203+ hours, or about 8.5 days. In reality, it will last less. First, once below a certain voltage threshold, it will not operate the Spyder's systems some time before it is completely dead, so the entire 21 amp hours may not be useable. Second, a battery's capacity deteriorates with time, so while a fresh battery may have 21 amp hours or more of capacity, an older battery could have less. Finally, this is not the only current draw on a Spyder. The computers, clock, etc., have a tiny draw, so there is more than 0.103 amps likely being drawn overall.
:agree: + 1 more factor that will cut into the theroretical 21 amp hr spec. As voltage drops due to the drain, amps used will go up further reducing the time.
