I've Got a Numax Heavy duty battery on my 4.6..

1200cca and 120ah it has sat for over 2 weeks and still spins her over like a top...

Hankook are alright, but the 2 year old one on my D2 could barely turn it over...

Are they the same battery trays?

Mf31-1000, is this in your P38 @Datatek? I'm not so sure battery is as good as it should be, I'd changed the fuel filter yesterday and bridged the fuel pump to help start the engine and when I turned the key the engine turned over sluggishly?
After I stopped the pump it and turned the key again it span over quite happily... It's only 720amp 93ah.
It starts great in the morning which contradicts the drain comaint??

I'd be interested in that link. Mine sits at Dublin airport for a fortnight every couple of months and I'm paranoid it will be dead when I get off an 8 hour flight at 5am.

I have the MF31-1000 in the P38, it's the second one, the first lasted 8 years until an alternator fault took it out, I have 2 in the Transit, one in the MR2 and one in the lawnmower. Oh and I just bought one for my daughters Citroen van. Best batteries I have come across in a long time. Last one came I think with a 5 year warranty too.
The P38 will sit for 3 to 4 weeks and still start quickly.

There are supply problems at the moment as all this stuff comes from China, the supplier I have been using has no stock but I have found the same items on the following links. the charge controller is a simple unit but does all that is needed.

I had the opposite luck with their batteries. I went through 3 in a little under a year before I gave up with them and got my money back. Which was a shame because it was a punchy battery, but even with me doing 500+ miles a week they wouldn't stay charged.
I don't even remember what I have no now (I think Yuasa), been on for easily 5 years and only died on me once when I was out of country for a few months and forgot to hook my solar charger.

I'd bet your alternator set point is 13.8 volts.

Hey Keith, how do you go about raising the set point?
