Battery and Battery Charger Details
Battery Pack:
The power source for the Lightweight OCU is a rechargeable 7.4 V Lithium-Ion battery pack
specifically designed for the Lightweight OCU. The battery pack is designed to provide 12-
hours of continuous operation. The battery pack contains an internal capacity monitor. This
monitor will be interrogated to report to the operator the remaining run time of the pack. The run
time report will be shown to the operator via the display at power on and when the status
SOFTKEY F4 is pressed.
The Battery Pack is installed in the back of the OCU. Do not allow any metal to come in contact
with the contact pads of the battery pack. If the battery contact pads do become shorted the
internal protection mechanism will cause the battery to open circuit. If the battery is placed in
the OCU the OCU is going to either not function or report a dead battery. Set the pack aside for
a few moments to allow the protection circuit to reset.
