Abstract
A vehicular battery operated charger (202) for charging an electronic device such as a radio (204) includes a controller (218). Controller (218) determines the battery voltage of the vehicles battery (222) and compares it to a threshold level stored in controller (218). Charger (202) will automatically charge radio battery (206) as long as the voltage level of the vehicles battery (222) does not drop below the threshold level stored in controller (218).
