Hi Keith; you could replace the battery with the # HM20008 but I would go ahead and replace the entire thing with # 20099. If you replace the whole kit you're getting the battery and a usable battery connection plus you don't have to worry about other parts wearing out (especially since one already did) which would end up costing you more in the long run.
