ABSTRACT:
TECHNICAL FIELD OF THE INVENTION
The present invention relates to batteries, and more particularly to a battery and stand system wherein the battery plugs into a stand without requiring external connections such as, for example, cables or bus bars.
BACKGROUND OF THE INVENTION
Typical battery connections are made through cabling or bus bars that are secured to the posts of a battery. The connections are made using screw type connections requiring an installer to properly torque each of the connections to a predetermined value. These connections require a periodic check and validation of the torque to ensure a good connection.
Batteries having posts extending from the surface of the battery require specialized packing for shipping. Under certain circumstances, the battery posts can create safety hazards as the battery can be shorted when the posts are simultaneously contacted by an external cable and debris.
A need has thus arisen for a battery having an improved connection system for connecting a battery to a battery stand.
SUMMARY OF THE INVENTION
In accordance with the present invention, a battery having a top wall, a bottom wall, a pair of end walls and a pair of side walls is provided. A pair of recesses are disposed within one of the battery walls. Battery post contacts are disposed within the recesses and are adapted for mating with post contacts located on a battery stand. The battery post contacts do not extend beyond the recesses.
In accordance with another aspect of the present invention, a battery and stand system is provided. The battery includes a top wall, a bottom wall, a pair of end walls, and a pair of side walls. A pair of recesses are disposed within one of the battery walls. Battery post contacts are disposed within the recesses. The stand includes a pair of stand post contacts which are adapted for mating with the battery post contacts within the battery recesses.
