What is claimed is:

CLAIMS

1. A battery having a flat top cover configuration, comprising:

a battery container including plural battery cells;

a battery cover sealed to the battery container, the primary cover including plural battery cell openings along a centerline of the battery;

plural battery terminals operatively connected to said plural battery cells and extending through the battery cover on a first side of the battery centerline;

a handle having a centerline attachment to the primary cover, the handle configured to be recessed with regard to the periphery of the battery cover and to wrap around the terminals in in a collapsed state on the first side of the battery centerline; and

at least one side vent communicating internal flame arrestor material with atmosphere, the at least one side vent positioned on a second side, opposite side of the battery centerline.

2. A battery in accordance with claim 1, wherein said battery cover includes: a primary battery cover sealed to the battery container, plural terminals operatively connected to said plural battery cells and extending through the primary cover, the handle having a centerline attachment to the primary cover, the handle configured to be recessed with regard to the periphery of the primary cover and to wrap around the terminals in in a collapsed state; and

a secondary cover having at least a portion provided opposite the centerline from the terminals and sealed to the primary cover, the secondary cover including at least one side vent communicating internal flame arrestor material with atmosphere, wherein the primary and secondary covers cooperate to define battery cell vents along the centerline of the battery.

3. A battery in accordance with claim 2,

wherein the primary cover further comprises:

plural cell openings, each of said plural cell openings including a raised wall portion having an upper circumferential wall opening in communication with a cell electrolyte overflow area that is defined by upstanding walls; and

wherein the secondary battery cover further comprises:

plural hollow posts configured to extend from a bottom portion thereof and at least partially within the cell openings of the primary battery cover, the top portion thereof being open to the hollow openings of the posts;

plural gas flow areas complementary to the configuration of the cell electrolyte overflow area of the primary battery cover and including wall channels to permit gasses to flow between such defined gas flow areas; and

at least one frit disposed between and in communication with said gas flow areas and an outside vent in the secondary battery cover.

4. A battery in accordance with claim 1, wherein the handle comprises a full periphery, suitcase handle having an curved section in a middle portion thereof and having two assembly pins on opposing sides of the handle outside of the curved section, the curved section providing an ergonomic handle contour in an upright state relative to the battery cover and a flat profile in a folded, inset state relative to the battery cover.

5. A battery in accordance with claim 4, wherein the curved section is an inwardly curved section between said terminals and wherein the battery cover has a complementary curved profile configured to receive the handle in a collapsed state.

6. A battery in accordance with claim 4, wherein said handle includes internal diagonal cross ribbing between the curved, ergonomic portion of the handle and the opposing, flat portion of the handle along the edge of the first cover adjacent the curved portion.

7. A battery in accordance with claim 3, wherein said hollow posts of said secondary cover are configured to act as an anti-spewing baffle as well as an alignment guide for the secondary cover.

8. A battery in accordance with claim 2, wherein at least one of said first and second covers includes alignment guides.
