Ok, I've got two calcium-calcium 105amp/hr 550cca batteries in the surf, one as a starter and the other as an Aux. It has been running sweet for ages, and even though the starter still shows good voltage even after 24/hrs rest it's just not cranking the old girl very well anymore. In fact this morning it was about 7c and it turned the engine over about 4 times and went CLICK! So I had to flick the aux over in parralell and start her with the both of them.

Of course if I had been running the lights and firdge etc etc while camping and this happened I'd be in deep doo doo, so I've got to do something about it.

The other problem is that running B100 biodiesel, cold mornings can mean up to 7 or 8 turns before she fire's instead of the 2-4 on normal diesel, so I'm going to need a hell of a battery for those cold camping morning's.

The Excide extreme I was always going to buy to replce the starter, but it's only 620CCA at best and doesn't seem to be much better than the 550CCA I've got.

Any recommendations for a kick ass starter battery? I've got reasonable room for it, had N70ZZ's in there with room to spare...

BTW - Can't afford to spend MEGA $$$ and I'm not interested AT ALL in the Optima's. Seen bad things first hand with those.
