Abstract

A terminal post seal arrangement for lead acid batteries is provided which may be used both as a moveable post seal or as a static post seal. In a first aspect of the subject invention, a battery is provided with an elastomeric sealing member rigidly fixed to both the cover of the battery and a bushing about a terminal post. Preferably, the sealing member includes a slack portion between its rigid connections which allows for relative movement between the bushing and the cover. In a second aspect of the subject invention, a collar is formed in the cover to bound the terminal post. The collar and/or the sealing member are formed at least partially tapered such that relative movement between the collar and the sealing member causes interferent engagement. It is preferred that interference between the collar and the sealing member become greater with increasing extent of relative movement.
