电池容量是通过在指定的能量消耗下保持一段时间的电量的能力来衡量的。这些值以安时（Ah）表示。
例如：供应15安培（A）时，300 Ah电池的使用寿命为20（h）小时。（15A x 20h）= 300 Ah

The Battery Capacity is measured with its ability to maintain power over a period of time with a specified consumption of energy. The values are indicated in Ampere hours (Ah).
As an example: the useful life of a 300 Ah battery when supplying 15 Ampere (A) is 20 (h) hours. (15A x 20h) = 300 Ah
