What type of battery life might I expect from my SnapShock Plus?
Most single-axis SSP recorders typically draw 1.8 milliamps when active. The triaxial version typically draws 3.4 milliamps. To estimate battery life, take the capacity of the battery and divide by the current draw. This will estimate the number of hours of operation from a brand new battery. Other factors to consider include the temperature of the system in the operating environment, and any current consumed while the system is in COM mode. Never leave a SSP in COM mode for the long-term: IrDA mode draws 3.6 ma of current, and hard-wired COM draws 24 milliamps, whenever the cable is plugged into your computer!
