Sure, it's just a battery. It's not even one of those big name brands you see on your local store shelves. But what you'll find is the OPT Varta brand lasts every bit as long!
Why waste precious gas and time getting the batteries you need for your astronomy equipment when you can simply order them at the same time? You'll find our value brand even saves money, so putting back a few in your telescope or accessory case means never having to worry about getting "caught in the dark"!
