Checking the Car-Battery Adapter

Checking the Car-Battery Adapter

There are two types of adapters but the checkout procedure is the same for both of them.

  1.  Unplug the Car-Battery Adapter cable from the computer.
  2.  Plug the Car-Battery Adapter into the cigarette lighter socket.

    NOTE: If the adapter is already plugged in, reseat it.

  3.  Measure the output voltage of the Car-Battery Adapter cable.


    Pin Voltage (Vdc)
    1 +19.0 to +21.0
    2 Ground


NOTE: If the output voltage from the cigarette lighter socket of the car is less than + 10.5 Vdc, the power-on indicator on the Car-Battery Adapter blinks and a continuous noise can be heard. The condition of the car battery should be checked by appropriate service personal.

The Car-Battery Adapter does not support operational charging.
