另外，蓄电池的电解液液面必须高于极板10 - 15毫米，不足时应及时添加蒸馏水。
In addition, the battery electrolyte liquid surface plate must be higher than 10-15 millimeter, should add distilled water shortage in time.
结果表明，电解液在毛面铜箔表面发生还原反应的程度比在光面铜箔表面显著，其阳极溶解电位比光面铜箔约低0。
The results indicate that the reducing reaction of electrolyte on the foil with rough surface is much visible than on that with shiny surface, the dissolution potential of matte copper foil is 0.
只需要拆开或者直接取下蓄电池盖，就可以检查电解液的液面高度。
Simply unscrew the battery caps or remove the covers to check the level.
