PURPOSE:To obtain a sealed lead-acid battery having high volume efficiency by arranging a connection rod piercing through the bottom in a battery jar at an adjacent cell or a terminal, connecting the rod to an electrode plate current collecting lead member, and bonding the bottom with an adhesive in a liquid-seal manner. CONSTITUTION:Connection rods 3 and terminals 4 are forcedly inserted into the bottom of a battery jar 1 by ultrasonic oscillations from the outside, then positive and negative electrode boards 5, 6 are superposed through a glass fiber separator 7. A polyurethane connection agent is charged into the electrodes such that the tip ends of the rods may be buried. An electrode group is inserted before they are hardened, and the tip ends of the rods and the terminals are inserted in the spaces of the grids of the positive and negative electrode plates. After a cover 8 is connected, electrolytic solution is poured by opening the cover 8, and a battery is completed after holes 9 are covered by valves 10. It is thus possible to have a sealed lead-acid battery having a high capacity efficiency.
