Abstract
Abstract An improved battery, an improved battery contact assembly and an improved method for attaching a battery to a substrate are provided. The battery includes a housing and a cover for attachment to the housing by crimping. During the crimping process a portion of the housing is bent over a portion of the cover such that a portion of the housing is substantially co-planar with a portion of the cover. Thus the two co-planar surfaces provide the positive and negative contact surfaces of the battery on a single side of the battery. The receiving portion of the contact assembly includes a substrate having a pair of contacts formed thereon. The contacts are shaped and sized to match the contact surfaces of the battery. The battery is attached to the substrate and traces using an electrically conducting adhesive.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
90 words
A method for mounting a battery on a substrate comprising the steps of: providing a substrate; providing a battery for mounting on said substrate, said battery having a first contact surface and a second contact surface; forming a first contact on said substrate; forming a second contact on said substrate; insulating said second contact from said first contact; and attaching said battery to said substrate using an electrically conductive adhesive to electrically connect said first contact surface to said first contact and said second contact surface to said second contact.
Claim 2
Independent Claim
90 words
A method for mounting a battery on a substrate comprising the steps of: providing a substrate; providing a battery for mounting on said substrate, said battery having a first contact surface and a second contact surface; forming a first contact on said substrate; forming a second contact on said substrate; insulating said second contact from said first contact; and attaching said battery to said substrate using an electrically conductive adhesive to electrically connect said first contact surface to said first contact and said second contact surface to said second contact.
