ABSTRACT:
Exposure or lack of adequate protection for the terminal portion of a battery against the environment is remedied by a protective `boot`, which is formed of a waterproof pliable material and is configured to fit snugly over the casing of the battery and seal the terminal portion of the battery against the surrounding environment. The battery `boot` may be molded from a rubber material or plasticized polyvinylchloride in the form of a cap portion and a sidewall portion integral with the cap portion. The sidewall portion is shaped to conform with an outer surface portion of the battery casing and is dimensioned such that, when the cover is pliably stretched so as to fit over the battery, the cap portion covers the terminals of the battery, while the sidewall portion fits tight against the battery casing and seals the outer surface portion of the battery against the entry of moisture, foreign matter and the like. To accommodate lead connections to the battery, while still providing a protective seal, the cap portion may be molded to include a sleeve portion which is sized to accommodate the passage of terminal leads therethrough, while simultaneously sealing the leads against the intrusion of moisture, foreign matter and the like.
