I just got this email from Canon USA:
It has been confirmed that counterfeit Canon lithium-ion batteries and chargers for Canon digital cameras and digital video camcorders are in circulation. In addition, it has been reported that counterfeit batteries have been considered the cause of some battery ruptures.
In many cases, counterfeit batteries and chargers are not equipped with protective devices required to meet international quality standards. Therefore, when these batteries or chargers are used or charged, they can cause abnormal heat or leakage, ignition, rupture and other malfunctions in the batteries, chargers, and digital cameras and video camcorders. There is concern that, in the worst case, not only could digital cameras and digital video camcorders be damaged, but fire, burns, blindness and other severe accidents could occur. Thus, to ensure customer safety, we urge our customers not to use counterfeit devices.
Please be advised that Canon is not responsible, and will not be liable, for any malfunctions, damages or injuries caused by non-Canon genuine lithium-ion batteries and/or battery chargers including, without limitation, counterfeit devices.
Recently, both in Japan and overseas, counterfeits of Canon's genuine lithium-ion battery packs and chargers have been frequently offered for sale on the Internet. Accordingly, please use caution when purchasing Canon lithium-ion battery packs and chargers on the Internet to ensure that they are genuine Canon brand.
Canon's genuine lithium-ion batteries have security labels on their packaging that identify them as genuine Canon products. When purchasing battery packs, please refer to this information. (See the following image for the labels.)
