Abstract
Abstract Disclosed herein is a storage battery heat maintenance unit which in the preferred embodiment comprises an adaptor post, U-tube heating coil and cap which mount over at least one terminal post of a standard electric storage battery of the type generally used in automotive vehicles. The U-tube heating coil is connected to the liquid cooling system of the vehicle's engine thereby circulating coolant about the terminal post. Heat is thereby conducted through the U-tube heating coil, the adaptor post and through the terminal post into the storage battery. In this way the internal temperature of the storage battery is raised to high efficiency operating temperatures under cold weather conditions.
