(JP9120846-A)      The battery (1) has a case (3), a cover (4), and an electrode group (2) comprising positive and negative electrode plates with separators between them in the case. A specified volume of electrolyte is immersed into the electrode group. Positive and negative poles (7,8) are connected to lead tags (10) of the two plates of the group, and a safety valve (9) is fixed in an air tight and liquid tight fashion to the cover.    The cover fitting part and the case upper edge are bonded to form a monoblock structure. A tube (6), which has a bottom protruding towards the inside of the cell, is joined to the cover, with the tube pointed end as close as possible to the upper central part of the group or in direct contact with the lead tab of one of the plates. A temperature sensor is inserted and fixed inside the tube so that the temperature sensing part is in direct contact with the inner surface of the tube pointed end.    ADVANTAGE -   Provides long-life sealed rechargeable battery with simple structure, which maintains state of hermetic seal for long time and has high reliability. Facilitates measurement of temperature in cell from outside in good response, thus controlling charge and discharge.
