Abstract:
A terminal for a battery has a mounting section and a contacting section. There is a torque ring between the mounting section and the contacting section. The mounting section is for holding the terminal within a battery cover, into which it preferably is injection molded. The terminal is a hollow body, which has an outer wall and an inner wall. At the contacting section, the outer wall is conically shaped. At the mounting section, the outer wall has at least one labyrinth ring forming a labyrinth. The inner wall comprises at least two sections. An upper section is essentially surrounded by the contacting section, and preferably has a conical shape. A lower section is essentially surrounded by the mounting section. The lower section preferably has in a lateral sectional view a concave shape. Between the upper section and the lower section, there is an edge. The edge at the inner wall is essentially surrounded by the torque ring at the outer wall.
Abstract:
Provided is a fluid type lead acid battery wherein charging is performed intermittently for a short duration each time, and high-rate discharging to a load is performed in a partial state of charge, said lead acid battery improving the charge acceptance and the life characteristic under PSOC relative to the prior art. A positive plate is used that has a positive active material total surface area per unit plate group volume set in a range of between 3.5 and 15.6 m 2 /cm 3 .
