The invented sealing component uses an acid-resistant thermosol whose softening temp. is less than 190 deg.C as raw material, and uses the characteristics of said thermosol which can be softened at lower temp., and even melted to attain the goal of tightly sealing accumulator (battery) end cover, pole and lead terminal bonding point. Said invention can effectively protect miniature lead-acid battery terminal and lead terminal bonding point against acid corrosion, and can raise the quality of said battery. Said sealing component is easy to manufacture and use. |
