ABSTRACT:
A rechargeable battery pack for a portable computer or other battery-powered device permits recharging of the battery while it is in the computer, or removal of the entire battery pack and recharging of the battery external to the computer by connecting an AC-DC converter directly to the battery pack. This permits removal of a battery pack and replacement with a charged battery pack, so that the portable computer is not occupied with battery charging and can be taken into the field while another battery pack is being charged. In the battery pack of the invention a DC power jack is located on the battery pack, identical to the DC jack on the exterior of the computer.
