Hey guess what?  i'm here to tell you how you can get for the price of 1, 2 items. This is the Renata battery tester. It is a great item to have in your store while changing batteries and a great discussion piece when customers come in to say let me test your battery. Here's what some of the functions it does. Watch test button it can do lithium batteries with the flick of a switch. it will do silver batteries as well.  This will test a battery that is already in a watch and it will also test just the battery itself. 2 for 1 for the price of one. Call 1-800-877-7777, ask your friendly sales associate about this and while you're on the phone please ask about the new Stuller battery club. You need to become a member . Have a Stullerific day and as usual I'm in your corner.
