The battery connectors appear identical to the stock parts in every respect, fit easily and worked well in my 189. They are very expensive for a few bits of bent metal, but Fluke can't (or won't) supply the parts so this is the only way to bring a meter that has had a severe battery leak back from the dead. There are cheaper far-east copies available, but I wasn't prepared to gamble on those - these work and fit properly. Recommended. (Reminder - don't leave AA batteries in a Fluke meter!)
