700 + 500 = 1200cca, i dont think there is a problem there, with batteries linked like that, as long as the cabling is up to it, will act like 1 bigger battery, might be time to upgrade the wire from the alternator to the battery as well.

I did look at the wire from the alt but it looked like a shyt job to do.

Nah, should be easy. You only have to do the main "heavy" wire.

Problem is I dont have a crimping tool, for the 2Gauge cable im using big arse 2gauge plugs with alan key screw holding the cable in.
Some of the other terminators ive found that you clamp on your self seem really poor.

I thought the same thing when I upgraded the alternator-> battery cable on my Feroza..... boy was I wrong!
The cable was in a loom with other wires, so I decided to leave the loom alone and just run a thick cable externally by itself (a lot easier than trying to disect one wire from the loom - being an EFI vehicle and all.) After running the new cable various electrical circuits had lost power. It turns out the original cable was spliced somewhere inside the loom and branched off to supply these circuits!!!

Be careful if doing such a mod. [/quote]
Was this due to an external regulator for the alternator?

Why not just leave the old cable in the circuit while supplementing it with the new larger one?
I've run a larger cable (400 amp welding flex) straight from the alternator positive to the battery positive.
Also used the same cable and upgraded most of my earth cables.

1. External regulator- no, an internal IC regulator.
2. I didn't leave the old cable (and run the new one in parallel) because I wanted to use the fusible link in it for the new heavy duty cable. It's very important to make sure that cable is fused!!!
3. I fixed it by joining the two cables together after the fusible link.
4. It is a bad idea to join two disimilar batteries together. Ideally they should both be bought at the same time and be exactly the same battery.
It can cause charging problems (ie. one may be overcharged/ the other under charged) due to them having to sit at the same voltage.
Also, if the voltages they naturally sit at with the ignition off are different the higher voltage battery will partially discharge into the lower one. If you buy two new batteries that are exactly the same you limit the chances of these things happening.
Basically it will make the new battery's life shorter.
Drivesafe (if he's around?) can elaborate and possbily explain it better than me.
