Hi, Hi what you have does look the same with this Part #:KJ097 Part Desc.:ASSY,HLDR,MTG,PLSTC,BTRY -> but this is for T310 when I looked up. Hope this helps.   
Is gf521 the correct perc6i  raid battery holder for a pe t310 please. Is there anywhere i can find the product codes and a proper descriptions please. The service tag descriptions must mean something to someone but nothing to me. Regards Graham
