(2) J8: External Battery Connector
The J8 allows the users to connector an external 4.5 to 6 VDC battery to the AR-B1380/AR-B1380A. If the
on-board battery is fully discharged, the SRAM disk will draw the battery current. The battery charger on
AR-B1380/AR-B1380A doesn’ t source charge current to the external battery which connects to J8.
