what size battery do i need for a citroen dispatch van?

[DarrenClarke]

i have a R reg citroen dispatch 1.9td with a 72 ah battery, i think it is knackered as puts out 14 amps when van running but drops to 11.ish when turned off, what size battery do i need to run the van, and would a 50ah battery have enough juice to run the van, as have spare one of them

all depends on the size of the engine but i would guess a duracell size c would do it.
