This invention relates to electric storage batteries, and particularly to a quick connection and mounting of the battery within a holder.
Most present automotive batteries used for starting the engines use the familiar SAE-type lead post terminals. Such 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 relatively difficult and inconvenient installation process.
It is the object of this invention to provide a mounting base for an engine starting battery in which the battery may be easily connected to the vehicle ignition system and snapped into the base without the use of tools. The mounting base completes the necessary electrical contact of the battery terminals to the electrical system of the automobile and also securely mounts the battery.


According to the invention, a battery mounting base has an upright at one end with two spring loaded contacts that mate with the terminals of a battery when the battery is inserted in the base. The mounting base has a locking mechanism that aligns the battery with the contacts and firmly anchors the battery without the need for further hold down hardware. A release lever on the base allows the battery to be withdrawn from the base.
The invention also resides in the combination of a battery and a mounting base in which the battery has a housing with a pair of spaced terminals extending from one face and the base includes a floor with an upright at one end having a pair of spaced contacts adapted to engage the terminals. Interengaging members on the battery housing and the base releasably lock the housing in the base.
The mounting base is particularly useful in mounting thin metal film batteries.

The spring loaded contacts insure a low resistance connection to the battery terminals so that available power to the ignition system is maximized.
The present invention eliminates the requirements for tools, increases the convenience for the installer, and decreases the likelihood of minor hand injuries or other injuries resulting from scraped or bruised knuckles, wrist strains, or electrical arcing caused by unintentional short circuiting of battery terminals by wrenches or other tools.
The foregoing and other objects and advantages of the invention will appear in the detailed description which follows. In the description, reference is made to the accompanying drawings which illustrate a preferred embodiment of the invention.


Fig. 1 is a view in perspective of a battery mounting base in accordance with the present invention;
Fig. 2 is a view in perspective of a battery to be mounted in the base of Fig. 1 ; and
Fig. 3 is a view in side elevation and partially in vertical section of a battery mounted in the base.


Referring to the drawings, the invention is shown in connection with a thin metal film lead- acid battery of the type that is illustrated and described in co-pending

U.S. application serial no. 09/008,719 filed January 19, 1998, and assigned to the assignee of this application. The disclosure of the co-pending application is hereby incorporated by reference as though fully set forth herein.
The battery 10 has a case which contains a plurality of spirally wound thin metal film cells (not shown). The case includes a body 11, a top 12, and a bottom 13 that are heat sealed to the body 11. As shown in the drawings, the edges of the top and bottom 12 and 13 project beyond the sides and ends of the body 11 to define rims. The body 11 includes integral, laterally projecting terminal housings 14 and 15 adjacent the lower portion of an end wall 16.
The cells within the body are serially connected to each other and to terminals

20 and 21 that are received in the terminal housings 14 and 15. The terminals are each formed of a body 22 of lead or a lead alloy that has a projecting face 23.
The mounting base, indicated generally by the numeral 30, is formed with side rails 31, a floor 32, and a front upright 33. A pair of contacts 34 are mounted in the face of the upright 33. The contacts 34 each include a copper plate 35 to which resilient conductive members 36 are attached. Each copper plate 35 is electrically connected to a wire 37 or 38 that is part of the vehicle electrical system. The copper plates 35 are received in recesses 39 in the upright 33 and are biased toward engagement with the battery terminals by springs 40. The wires 37 and 38 have metal ferrules 45 through which pins 46 extend to limit the outward bias of the springs 40.

The base 30 includes clips 50 rising from each side rail 31. The clips 50 have ledges 51 that overlie the floor 32 of the base. The ledges 51 are spaced above the floor 32 a distance equal to the height of the rim of the bottom 13 of the battery 10.

The base 30 also has a latch 55 connected to the bottom 32 by a living hinge section 56. The latch 55 includes an upright face 57 and a release lever 58 extending away from the face 57.
The battery 10 is inserted in the base 30 by sliding the battery bottom 13 beneath the ledges 51 of the chips 50. The faces 23 of the terminals 20 and 21 engage the contacts 34 which will yield until the rear of the bottom 13 of the battery 10 seats against the face 57 of the latch 55 which firmly holds the battery in the base. The battery 10 is removed by lowering the release lever 58 to allow the battery to be slid out of the base 30.
