F A Q
How to calculate the WH of a Battery?
nominal Voltage) x Capacity in Ampere-hours
V x Ah = Wh oder V x mAh / 1000 = Wh
IATA requires, that for Lithium ion batteries of over 100 Wh that are being produced after 31. Dezember 2011,
that the WH are printed on the Battery. For Lithium ion batteries of or under 100 WH produced later than
01.01.2009 also the WH has to be printed on.
What are “Buttoncells“ and how to treat “Battery Packs“?
Button cells are referred as a “single cell battery“ therefore it is not considered as a Battery for this
understanding. So we would like to speak in this matter about performance limitations for cells and not
batteries. A Battery has more than one cell. Button cells containing in equipment (for example in a Watch) are
not restricted in the IATA DG Regulation; this also includes Overpacks. A Battery Pack contains more than one
Battery and is considered as a Battery. Example: a “Battery Pack“ with 6 Batteries of each 40 WH equal a total
of 240 WH; therfore, it becomes a regular DG Class 9 Shipment.
