Abstract
A method and apparatus for a mobile battery charging arrangement (100, 104, 114) utilizes a controllable power switch (306) to selectively switch power from a vehicular power source (114), such as a vehicle battery, to a battery charging circuit (101) to provide a charge to a rechargeable portable battery (104) for a portable battery operated device such as a portable communication radio (106). A battery present detector (102) controls the controllable power switch (306) to switch in the power from the vehicular battery power source (114) to the battery charging circuit (101) only while the rechargeable portable battery (104) is electrically coupled to the battery charging circuit (101) for receiving a charge therefrom.
