Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
191 words
A storage battery having a plurality of cells in a container and a cover therefor with each cell comprising positive plates, negative plates, separators between the positive and negative plates, and electrolyte, said container or cover or both the container and cover being polypropylene, said battery having 2 polypropylene lifting ears located on opposite sides of the battery, each lifting ear extending above the top of the battery with the portion above the battery having a hole therein adapted to removeably receive the end of a carrying strap, said lifting ears being located diagonally from each other so that when the carrying strap is inserted in the lifting ears the center of gravity of the battery in an upright position falls approximately under the center of the carrying strap, and both of said lifting ears being flexed at the time they are made so as to orient the molecules to provide a tough pliant hinge section which is located just above the top of the battery whereby the portion of the lifting ears extending above the top of the battery can be folded down repeatedly upon the top of the battery.
