Hi Charile,

What does "typical" mean for this battery? Please note that certification 
requirements for that battery will vary a bit with the actual device 
application and the construction of that battery.

For the USA, please note that UL 1642 pertains mostly to individual battery 
cells. UL 2054 would be the safety standard for battery packs here in the US. 
Also if that battery is targeted for the cellular telephone market in the US, 
then be aware that CTIA certification (IEEE 1725) will probably be required 
(also includes the charger or external power supply) if PTCRB certification is 
pursued.

For international, IEC 62133 should suffice, but please note that for the EU, 
EN 62133 might need to be complied with although it is not included in the 
R&TTED harmonized standards list. Please note that some countries have their 
own unique requirements for mobile device batteries.

And, IATA requirements are indeed mandatory and can generally be satisfied with 
successful UN T1-T8 testing.

IHTH.

Best regards,

Ron

Subject: [PSES] Safety requirements for batteries in Mobile Phones

Group.

I have a typical Li-Ion 3.7V 1.4 Ah mobile phone battery, and am trying to 
identify compulsory and recommended safety requirements . . . .

"IATA Guidance Document Transport of Lithium Metal and Lithium Ion Batteries 
(2010)" appears compulsory

Are UL1642 / IEC62133 recommended / optional / required under certain 
circumstances?

Anything else required.

Regards
Charlie
