where abouts are you?

 

Greenock just outside GLasgow !

 

would say the batt is nackard, the alternator is sticking 13 volts in, but it aint holding it,

 

It's the battery, if it were discharging through the alt due to defective diodes it would not be anywhere near as quick to do so as this.
I would clean up all connections anyway, as the batteries age the plates break up and the broken bits fall to the bottom causing a permanent short in that cell, years ago some were washed out then refilled and got a bit more life out of them, but most are sealed these days.
I always use Varta Blue myself, expensive but get what you pay for.
carbatteryshop.co.uk is a good site
