Hi Scoobie, with regard to batteries for starting diesel Disco's it's the CCA or MCA that counts much more than the amp/hr rating. This is because CCA is the rating which shows how much power the battery has - short term - to start the engine.

I used to have a TDi and I put in an Optima battery, only 50amp/hr rated but over 800CCA and that worked great even in the coldest weather - bit pricey though.

If you do a Google search for Tanya Batteries, they do a good battery at 1000 MCA (approx 850CCA) and 90amp/hr from memory, for about £70 delivered.

Good luck

Wot he said^^^^
I got one of these
Numax CXV-X 1000 Amp - Leisure Batteries - Numax Leisure Batteries

I would also clean all main earth cables and I added one from battery to engine.

A few weeks ago I was putting petrol in with the diesel because an old mechanic told me that diesel will get a bit thick and will also freeze in cold weather.
Anyway no problem firing up in the mornings.
For the last 2 weeks I haven't bothered putting a cupfull of petrol in with the diesel.
Twice last week when it was -3, I had to put the power pack to it to get it to fire up.
Yes, it does help to have clean terminals and spraying WD40 into the alt & Starter helps, but I agree - putting petrol into the diesel does help for easier starting on cold mornings.
