Used to be very expensive but still worth every penny. They were handled by Barlow World one time !!!!!!!!!! that explains that.
Now I think that you can buy them direct in the UK I believe that the price is now about 15K Sterling but don't hold me to that.
Look them up on the Internet --- Honestly for sulphation they work. More importantly you get exact information on the battery condition so you don't have to take a chance, or if you do at least it is a calculated one.
If you have any trouble getting info I will find a contact in Sweden for you
I am away for the next 10 days but if you want to contact me on ndamery at trident dot ie I will help you on my return.
