D. How are component cells connected to form a battery?
D--在IATA DGR 规定中，电池芯是如何进行连接以组成电池的？
Cells in batteries may be connected in parallel, in series, or in a combination of the two. When cells are connected in series the voltage of the battery increases but the capacity in ampere-hours (Ah) does not change. By contrast, when cells are connected in parallel the capacity in ampere-hours of the battery (Ah) increases but the voltage stays the same.
电池中的电池芯可以通过并联、串联或者两种方式组合的方式进行连接。当电池芯串联时电池的电压升高但容量（以安培小时Ah 为单位）不变。相反，电池芯并联时容量增加而电压不变。
