PURPOSE: A maintenance-free tube type storage battery is provided to avoid maintenance by designing an liquid electrolyte to be circulated and to prevent temperature rise since the liquid electrolyte is filled inside a electrode material. CONSTITUTION: A maintenance-free tube type storage battery comprises a polypropylene case(12), a cover(14) covering the polypropylene case, a charge-state displayer(16), a positive electrode terminal(20) and a negative electrode terminal(22) which stores voltage in charging and supplies power to the load when voltage is not stored, a plurality of negative electrode plates(24), positive electrode plates(26) installed between the negative electrode plates, a pair of posts with the positive electrode and negative electrode, a strap connector for connecting cells, and a plurality of separators(32) that surround components to prevent internal short. |
