PLC 5/40 Battery

Can anybody tell me what is the Catalog # of battery for my PLC 5/40 1785-L40B/E processor.I searched on AB sites but i found several list of catalog # for PLC 5/40 and i am confused which one is for my plc. The currently installed battery has a code: 95546902 Rev A 9707 PROMARK and made by Matsushita (generic i think). Our local distributor insisted that they the catalog # before they qoute.

Thanks in advance.
