2. The battery terminal bushing of claim 1 , wherein the anti-torque region comprises a surface area of at least approximately 200 mm2.
3. The battery terminal bushing of claim 1 , wherein the bushing has a resistance to torque which is greater than 150 inch-pounds of torque.
4. The battery terminal bushing of claim 1 , wherein the bushing has a resistance to torque which is at least 200 inch-pounds of torque, before reaching a failure mode.
5. The battery ter final bushing of claim 1 , wherein the battery terminal bushing is a side terminal bushing is configured to mount in a battery housing sidewall.
6. The battery terminal bushing of claim 1 , wherein the battery terminal bushing is configured to mount in a battery cover.
7. The battery terminal bushing of claim 1 , wherein the anti-torque region comprises a first anti-torque feature comprising an anti-torque ring proximate the exterior end and a second anti-torque feature comprising an anti-torque pattern proximate the insertion end and spaced apart from the first anti-torque feature.
8. A lead acid battery comprising the battery terminal bushing of claim 1 .
9. A battery terminal bushing comprising:
a body having an insertion end and an exterior end opposite the insertion end;
one or more sealing rings on the body; and
a plurality of anti-torque features on an outer surface of the body configured to fixedly engage with a battery housing material, wherein the plurality of anti-torque features comprise a surface area of at least approximately 200 mm2 and provide a resistance to torque which is greater than 150 inch-pounds of torque.
10. The battery terminal bushing of claim 9 , wherein the bushing has a resistance to torque which is at least 200 inch-pounds of torque, before reaching a failure mode.
11. The battery terminal bushing of claim 9 , wherein the battery terminal bushing is a side terminal bushing configured to mount in a battery housing sidewall.
12. The battery terminal bushing of claim 9 , wherein the battery terminal bushing is configured to mount in a battery cover.
13. The battery terminal bushing of claim 9 , wherein the plurality of anti-torque features comprise a first anti-torque feature including an anti-torque ring proximate the exterior end and a second anti-torque feature comprises an anti-torque pattern proximate the insertion end and spaced apart from the first anti-torque feature.
14. The battery terminal bushing of claim 13 , wherein the first anti-torque feature includes a pattern of alternating peaks and valleys in a form of teeth configured to engage and be contained within the battery housing material.
15. The battery terminal bushing of claim 13 , wherein the second anti-torque feature comprises a pattern of peaks, valleys, curves, and undulations to form a variation in dimension on a surface.
16. The battery terminal bushing of claim 15 , wherein the pattern surrounds a connector segment, the connector segment configured to attach to a battery terminal post.
17. The battery terminal bushing of claim 13 , wherein the second anti-torque feature comprises a pattern of ribs separated by valleys extending in opposite directions from a central segment, the pattern of ribs further comprising two end regions having a substantially semi-circular shape.
18. The battery terminal bushing of claim 13 , wherein the second anti-torque feature comprises a pattern of ribs extending in perpendicular directions from each other and surrounding a central segment, the pattern of ribs configured to include a notch.
19. A lead acid battery comprising the battery terminal bushing of claim 10 .
20. A battery terminal bushing comprising:
a body having an insertion end and an exterior end opposite the insertion end;
one or more sealing rings on the body between the insertion end and the exterior end;
a terminal post connector segment on the insertion end of the body; and
an anti-torque region of increased surface area on one or more surfaces of the body configured to fixedly engage and be contained within the battery housing material, the anti-torque region comprising a first anti-torque feature having an anti-torque ring proximate the exterior end and a second anti-torque feature including an anti-torque pattern proximate the insertion end and spaced apart from the first anti-torque feature, the first anti-torque feature including a pattern of alternating peaks and valleys in a form of teeth and the second anti-torque feature including a pattern of peaks, valleys, curves, and undulations to form a variation in dimension on the one or more surfaces.
