Thanks. Don't know anything about the Voyager but I'll give them a ring.
Why Freedom I'll tell you. I have two Freedom 60's on the boat, the last one was replaced about 10 years ago, it's still OK the one that needs replacing is at least 15 yers old.
These batteries are maintenance free and hold there charge for a very long period, even if unused over the winter. The ones I use have side terminals which are connected by bolts, very secure. This is an American idea and is standard on many USA cars.
