Our boat fitter recommended them at the fitting out stage, but I resisted. With hindsight, I am glad that I went with the cheapy Trojans, which are now still working well in their 9th year

Excellent true traction batteries. They'll last for many, many years if looked after. You'd have to really seriously abuse them to kill them. You'd need a mortgage to buy them. I'm not sure they'd offer a boater much more over semi-tractions.

And a weight lifter to install them!

When valve regulated sealed lead acid batteries first began to be used around 1980, BT tried Chloride, Tungsten and Rolls batteries. All were stated to last 10 years.

The Chloride and Tungsten batteries suffered many premature failures,  mainly due to corrosion between the pure lead group bar and the lead calcium alloy plates, but the Rolls which used pure lead plates didn't.  However BT chose to go with Tungsten and Chloride because, despite the failures (which were replaced under warranty) the Rolls simply were too expensive. 

The high failure rate and BT's unrelenting attitude to warranty claims brought Chloride and Tungsten to bankruptcy, and they no longer make batteries for the critical power industry.

Now BT use Yuasa batteries, which perform almost as well as Rolls, but at an affordable price.
