Abstract
A vent cap includes a main body configured to be received within an opening in a cover of a battery cell, the main body including a fluid flow path formed therethrough to facilitate a flow of a fluid to be added to the battery cell, a valve moveably disposed within the flow path to selectively open and close the fluid flow path, and a float coupled to the valve and positioned to float adjacent a surface of a fluid disposed within the battery cell, the float causing the valve to open the fluid flow path at a pre-determined fluid level within the battery cell to permit the fluid to be added to the battery cell to flow through the fluid flow path, wherein the fluid flow path is configured to minimize an impinging on the float by the fluid to be added to the battery cell.
