2.4. Battery Charger Tests
2.4.1. Connect battery charger module to C&I main board connector (JP2) and verify that the voltage
across BAT + and BAT- on the charger board is set to 6.9 Vdc with 680 Ohm resistor connected
across battery leads. Otherwise, adjust R7 Pot to set battery voltage to 6.9Vdc.
Pass__Fail___
2.4.2. Connect battery leads to the battery terminals and verify that voltage across battery terminals
has reached to 6.9Vdc (fully charged).
Pass__Fail___
2.4.3. Disconnect AC power to C&I main board and verify that the LEDs stays on (good indication that
UUT is powered by battery only).
Pass__Fail___
2.4.4. Remove battery charger module from C&I board with battery leads disconnected from battery
terminals. Then connect a dc power supply to battery leads and slowly increase the voltage from
0-6.5 Vdc while monitoring battery status pin (JP1-4). Verify that battery status pin goes high at
5.25 Vdc
Pass__Fail___
2.4.5. Then, lower the dc Power supplies voltage slowly and verify that battery status pin (JP1-4) goes
low at 5.0Vdc.
Pass__Fail___
