  • Patent number: 5212025
    Abstract: A battery container is provided with a battery cover having side walls so that a gap is formed between the side walls of the container and the side walls of the cover. The upper end portion of a bottomed heat-shielding case is inserted into this gap so that the heat-shielding case is detachably attached to the battery container and covers the container and forms a space between the container and the case. The space between the container and case is closed to air outside the case and air convection between the outside air and the air inside the space can be prevented thereby increasing the heat-shielding effect for protecting the storage battery from high temperatures. Additionally, the heat-shielding case is designed to be attached securely to the battery container (1) to make one body therewith, making it easier to mount and dismount them in an automobile engine compartment.

  • Patent number: 4724190
    Abstract: A storage battery including a container and a cover. The container is partitioned into a plurality of cell chambers by a plurality of partition walls. Each cell chamber has a cell therein which is composed of positive and negative plates. The negative and positive plates are connected by negative and positive straps, respectively. An intercell connecting conductor connects negative and positive straps from adjacent cells through an opening in the partition wall. Each intercell connecting conductor includes a horizontal base attached to one of the straps, and an ear which extends obliquely upwardly from the base to the opening in the partition wall. The opening in the partition wall and the ear are laterally offset from the base so that they are vertically unaligned with the base.
