Don't know why you wouldn't be able to. Radio Shack sells a repair kit with both connectors that are already wired. Actually they sell two kits, one for 7.2v and another for 9.6v with the only difference being the wire guage. They probably sell the connectors seperately so you could make the battery leads any length you want.
7.2v part # 23-444 so 9.6v is either 23-443 or 23-445
