Abstract
The invention concerns a battery jar having a modified interior side and end wall structure that both increases the electrical rating of the battery and reduces the quantity of material required to produce the battery jar itself. The interior of the jar is divided into upper, middle and lower sections and the wall thickness in each is different. The side wall thickness in the middle section is reduced by about 36-40% of the side wall to 60-64% of the thickness in the upper section and the side wall thickness in the bottom section is reduced by about 16 to about 20% of the upper to 80-84% section sidewall thickness. A plurality of ribs are also used on the end walls to maintain the length dimension within the jar between opposing end walls.
