Hello Scott,

You did not mention the type of battery you are using but I am guessing it is
Lithium Ion??

In this case I don't think there really is any easy way to guarantee safety of
a rechargeable Lithium Ion battery pack without extensive testing to current
International Standards. Just an FYI the International Regulatory bodies are
in the process of revising the current standards to try to make them more
stringent due to concerns related to recent field issues.

In addition to the UL standards you mentioned I would look at the IEC/EN
requirements such as IEC/EN62133. I don't believe there is a energy limit in
the UL or IEC/EN standards for required compliance.

Japan (implemented in November 20, 2008) and Korea (effective January 1, 2010)
have also passed new laws regulating Lithium Batteries where any battery which
has an energy density greater than 400W/L must meet specific construction and
test requirements. Batteries below this energy density level are exempt.
Korean requirements are similar to Japan's

Here are the links for the Japan regs

There are also International shipping regulations which have energy level
limits and testing requirements. The manufacturer of the cell should be able
to provide you with an appropriate test report. To satisfy the testing
requirements for the shipping regs.

Subject: How to determine if battery-operated product is safe or not

We have an USB rechargeable battery-operated video clip/MP3 player.  As
battery-operated products do not fall into LVD directive, what can we apply
the basis to determine the product safe or not?  Looking at historical
safety hazard reports on the market, there was not much any recall on this
type of products except the explosion of rechargeable battery pack.
However, the possible explosion of rechargeable battery pack cannot be
picked up by LVD directive or dedicated UL1642/2054 battery cell/pack
standards.  Otherwise, Sony did not need to recall millions of battery packs
and the said standards are not required the review.  What is potential
hazard do we need to look at this type of products? As the safety hazard is
tied with power energy, is there any reference that there is no safety
concern if the power energy is below certain level?

Thanks,

Scott
