John:

 

In this case I would ask manufacturer (thru your purchasing channel)
regarding marking requirements agreed as a certification requirement from
the UL. That should be condition of acceptability. Have that letter or
document available at time of UL inspection.

Other way, I handed was to ask for certificate (or document) of acceptance
(CofA or DofA) of shipment form your supplier, stating quantity part number
order number meets UL component marking requirements. And store it with
incoming inspection.

Subject: [PSES] Lithium Button Cell Battery - NRTL markings

 

Hi guys,

 

We are having a heck of time proving a button cell is actually UR - CR2354.

 

UL IQ says it's UR.  The Battery is not marked.  The Guide Card allows the
marking to be on "packaging".  Our customer purchases the CR2354 on-line.
The packaging it comes in is not marked.  Is it possible the UR mark is on
the Bulk packaging that the on-line supplier would have?

 

Best Regards and Be Safe,

 

John
