PREAMBLE OF THE DESCRIPTION:
THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE INVENTION AND THE MANNER IN WHICH IT IS TO BE PERFORMED

A) TECHNICAL FIELD
[0001] The present invention generally relates to battery operated devices such as electronic controllers, DC motors or AC motors through inverter. The present invention more particularly relates to an apparatus and method for changing the discharged batteries in electronic devices.
B) BACKGROUND OF THE INVENTION
[0002] The Quick Change (QC) mechanism was built to explore the feasibility of quick battery exchange as an alternative to on-board battery recharging process. The Quick change is a process in which the whole battery is mechanically removed from battery operated devices and replaced with a fully charged battery. Presently the automotive batteries are used for starting engines, in industrial applications to power the electrical and electronic devices which use familiar SAE-type lead post terminals. The SAE-type lead post terminals usually require a lead ring-type connector on the cable. The lead ring is typically tightened by means of a nut and bolt thereby requiring tools for installation and resulting in a cumbersome and inconvenient installation process. Moreover the battery change process consumes time thereby increasing down time of the battery operated devices. Also there are chances of sparking due to the removal and the insertion of battery terminals during the battery change process thereby increasing the hazard to the operating personnel during the battery change process.

[0003] In one scheme, the flat bladed tools are inserted between the batteries and the device housing to pry the battery from a battery compartment. Another technique uses a special gripping tool to engage and to remove the battery. In yet another scheme, a technique is provided for manually lifting a battery from a battery holder or an elongated rod and a carriage is used for inserting and removing the battery from the battery operated devices. Although different techniques have been developed to remove the discharged batteries, significant dexterity is often required to extricate the discharged batteries from the battery compartment of the battery operated devices.
[0004] In light of the foregoing discussion, there exists a need for an improved battery replacement mechanism to replace battery quickly and easily. Also there exists a need for a rapid battery replacement mechanism without using tools such as spanners or screw drivers.
[0003] The above mentioned shortcomings, disadvantages and problems are addressed herein and which will be understood by reading and studying the following specification.
C) OBJECT OF THE INVENTION
