Koh, UL2054 applies to only the batteries themselves and not to the equipment. If your question relates to the equipment, then I am sure that 60950 is the appropriate standard. Moreover, 60950 (in whatever guise) is based on an international IEC standard, so working to that can potentially give you access to more markets than just the US providing that you take into account the relevant national variations and obtain an IEC CB report.

These batteries can either be user replaceable or non-replaceable. These batteries are being charged when the players is connected either to PC USB port or mains AC/DC power adaptors. Which UL standard that it must conform to? UL 2054 or UL60950? What are the common test and difference test called by both standards? Like to know of the general test called by each standard before we proceed to purchase the UL2054 std. If testing just to UL60950, is it sufficient? Can we still assume product is still safe.
