E. How do I determine the watt-hour rating for a particular lithium ion battery?
E--在IATA DGR 规定中，如何确定锂离子电池的额定瓦特小时？
The watt-hour (Wh) rating is a measure by which lithium ion batteries are regulated.Section II Lithium ion batteries manufactured after 1 January 2009 are required to be marked with the watt-hour rating. Section I Lithium ion batteries manufactured after 31 December 2011 are required to be marked with the watt-hour
rating.
额定瓦特小时(Wh)是一种规范锂离子电池的计量标准。Section II 中要求 2009 年1 月1 日以后生产的锂离子电池都要求用额定瓦特小时进行标记。sectionI 中要求2011 年12 月31 日后生产的锂离子电池都需要标注瓦时。
You can also arrive at the number of watt-hours your battery provides if you know the battery’s nominal voltage (V) and capacity in ampere-hours (Ah):
如果已知电池的标称电压(V )和标称容量(Ah)，可以通过计算得到额定瓦特小时的数值：Wh= V x Ah 安培乘以标称电压等于瓦时
This information is often marked on the battery.
标称电压和标称容量通常标记在电池上。
Note that if only the milli-ampere-hours (mAh) are marked on the battery then divide that number by 1000 to get ampere-hours (Ah) (i.e. 4400 mAh / 1000 = 4.4. Ah).
请注意：如果电池上只标记有毫安时(mAh)，可将该数值除以1000 得到安培小时(Ah)
(例, 4400 mAh / 1000 = 4.4. Ah)。
Most lithium ion batteries marketed to consumers are below 100 watt-hours. If you are unsure of the watt-hour rating of your lithium ion battery, contact the manufacturer.
消费者使用的大多数锂离子电池其额定瓦特小时都低于100 瓦特小时。如果无法确定锂离子电池的额定瓦特小时，应联络生产商。
