I have just placed on board two 140amp Varta LFD140. They replace two Banner originally installed by Bavaria, this were in fact 135amp starter batteries and although they worked was not really built for the service battery job. Also starter batteries have base clamps. Like others I have put a timber beading around the base and a clamp across the top. These new batteries are sealed and don't need ventilation hoses either. I went to Tayna but actually got them locally in Torquay for the same price and the next day.
