Re: Battery tester for CR3V on *ist d.
I dont know of any inexpensive testers for 3v Lithium batteries. I test them regularly as part of my business for watches but I would not worry too much these cells will power a complex digital watch 24 hours a day for years. I imagine that the one in the *istD is good for a least ten years.
