Leisure battery smelling and hot. Advice please

Yes, had that, though luckily not while away touring. Suspect a cell in the Battery has boiled dry and gone short circuit. Halfords usually have a branch in most largish towns, and sell reasonably priced Leisure Batteries.....with good guarantees. Which are easy to use (unlike a lot of cheaper online suppliers). A lot of 'so called'  Maintenance Free leisure batteries are nothing of the kind, and need topping up with distilled water. 

ps Any dog who smells anything like a boiled dry battery has a serious problem and needs to see a vet.

Thanks for all the replies and your help.  After the battery cooled we disconnected it but haven’t tried to remove it yet.  We go home tomorrow so will call at Halfords on the way.

Luckily I wasn’t wearing my flowery dress, hard to do when you don’t have one, and our dog smells of dog biscuits, not rotten eggs thank goodness.

Halfords' staff generally don't know their bum from their elbow. You need a leisure battery & not a car battery, they're not quite the same. You need at the very least a camping shop or preferably a place that just sell batteries & know what they're talking about.

I bought a new caravan battery for a project earlier this month from a battery company on e-Bay and it was brought to my doorstep the next morning. Good I didn't try Half Ords as the local branch has moved and changed into a major stockist of children's bicycles and air fresheners.

Seems good quality - call back in three years for the usage report.

Its not Halfords staff knowledge, but their guarantees and ease of returning a faulty battery that I am recommending, and they DO sell good 110ah Leisure Batteries at most if not all branches.
