Trimble's AA Battery Module for its Nomad rugged handheld computer allows users to run the Nomad an average of four hours using two AA alkaline batteries without affecting its rugged performance capabilities. With the AA Battery Module attached, the Nomad retains its MIL-STD-810F rating for drops, vibration and temperature extremes. And unlike other rugged handhelds that reset if dropped while running on AA batteries, the Nomad uses a special capacitor to prevent the unit from resetting after a drop or other shock.
