麻烦大家帮忙看看这句话里面有语法错误吗，错在哪给讲解下吧，非常感谢好心人~！

Question

The walkie-talkie are used so long time that some of them can not work normally, one walkie-talkie needs two battery for charging alternately.

Answer 1

首先，你的名词大哥大是单数的，后面的are却是复数用的，因此大哥大后面应该加s变成复数。
so long前面请加上for。
其实上把time删掉会更通顺，不用怕，没关系的。
normally换成properly会更通顺，前面两条是语法问题，请修正。后面两条只是为了通顺的修改，看楼主自己定夺。
以上。

Answer 2

so long time that 改为 such long time that
some 应该和others搭配，有点重复，从句可直接改为：
some can not work normally,others need two battery for charging alternately.

Answer 3

The walkie-talkies have been used for such a long time so that some of them can not work normally. One walkie-talkie needs two batteries for charging alternately.
