start to die
It will sulphate up and die. Within a few months usually.
Generally I agree, but not in a few months unless already on last legs. Afteral, they spend at least that time in the shops and warehouses. My van was unused for 3 years and the battery is still able to crank over its 6 cyl engine with ease summer or winter.

If it's in good condition and fully charged it will retain its charge for a very long time. A year should be OK. Lead acid are better than pretty well any other type of rechargeable in this respect.
especially if the battery is clean and dry and not stood on concrete, though why that seems to be a problem I don't know!
concrete is cold and has a habit of causing condensation
It's one of those historic issues from when they where in rubber cases.
James has brought this to us :
That depends upon the condition of the battery and its state of charge when put in the cupboard. If in any doubt charge it up every month.
