Here's the story so far, the car doesn't get used much so the battery goes flat quite often and it fails to start, usually ok after it gets charged.
Recently after charged it either just turns over really slow or clicks so I bought a new battery and didn't seem any better so I then bought a new starter and its still the same just clicks the starter however as soon as I put jump leads on it starts instantly.

Any ideas on what else I can try.

Cheers
Norman
