Abstract
Abstract This invention relates to improvements in electrical connections provided between the terminal connectors on a battery casing and their respective intercell connectors which pass through the intercell walls in multi-cell batteries. The improvement is directed towards the prevention of leakage of electrolyte through the peripheral wall of the battery casing as well as between the cells positioned therein. This is achieved mainly by deformation of the battery casing and intercell walls so that the contact surface between the battery casing and the cell wall and the respective connectors is increased.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
102 words
A battery construction for electrically connecting the plate elements of a storage battery comprising, a pair of intercell connectors, one connector having an offstanding protubErance, the second connector having a circumferential recess, a partition between said connectors, said partition having means defining an aperture therein and an offstanding collar surrounding said aperture and including a terminal portion, the means defining said aperture in said partition encompassing the protuberance on said one connector with the terminal portion of said collar being forced into the recess in said second connector, the protuberance on said one connector contacting and being welded to said second connector.
Claim 2
Dependent Claim
102 words
A battery construction for electrically connecting the plate elements of a storage battery comprising, a pair of intercell connectors, one connector having an offstanding protubErance, the second connector having a circumferential recess, a partition between said connectors, said partition having means defining an aperture therein and an offstanding collar surrounding said aperture and including a terminal portion, the means defining said aperture in said partition encompassing the protuberance on said one connector with the terminal portion of said collar being forced into the recess in said second connector, the protuberance on said one connector contacting and being welded to said second connector.
Claim 3
Dependent Claim
28 words
A battery construction as claimed in claim 1, wherein the second connector includes an offstanding protuberance which contacts and is welded to said protuberance on said one connector.
Claim 4
Dependent Claim
20 words
