Range Rover batteries?

[trigger7mm]

Can someone please tell me where I can get replacement batteries for my Tru Glow Range Rover single pin sight? I am from Alberta, Canada and expect that I'll have to order them for the U.S.A. I'm new to the forum and am happy to be part of it. By the way Ralph and Vicky, it was an honor to meet you both at Huntfest in Edmonton last summer!! Thank you for the help.......Dean.
