Has a look at my battery today on my DII and was suprised to see that my + terminal connector was all crusty. 10-15mm of white and green crust all over the terminal connector, to the point that is was unreconizable!
Anyone ever seen this and know why this would happen? The truck is 18months and has 16K miles on it. Dealer say that is not covered under warranty...
Also where do you guys mount a second battery on a DII?

Check the charge rate. Check the fluid level.
Clean off the mess with a baking soda and warm water mixture using a brush.
After making sure that the terminal is tight smear some grease or petrolium jelly (vaseline) over the whole terminal.
There are some commercial spray on products that would do the same job.
Only place I can see where a spare battery may fit is between the ABS pump and the firewall.

The buildup you found on the top of your battery is a result of chemistry that if it didn't happen, life as we know it would not exist.
As to why you're seeing excessive amounts on your battery may be due to a number of seemingly unrelated causes. You may have a tiny crack in the battery case near the terminal allowing the electrolyte to creep up and out as the battery charges/discharges. Your alternator may be overcharging the battery thus driving more corrosive fumes out of the battery. It's bad enough the electrolyte is sulfuric acid, but the gas that is evolved is hydrogen which is every bit as reactive with everything on earth.
The battery may have suffered some damage as the terminals were installed, or perhaps some mechanical damage was done to it.
Having said that, it is not all that uncommon to find some crud growing on one's battery terminals, however, it sounds as though yours may be excessive.
As Streak said, scrape it off, wash it off (lots of water will work just as well, it just takes a lot more) and then coat it to try to keep the air away from it. I personally use a compound just for this, but don't know if it is available to consumers, or just available to industrial users.
As for your secondary battery, I am not as familiar with the DII as the DI, but on the DI, the secondary battery commonly is placed in front of the airbox.

You can coat the terminals with petroleum jelly to prevent corrosion. |

Thanks Guy
Shouldn't the dealer coat the battery terminals during servicing? I know they do on my other vehicle...
It looks like I have to remove the battery and jack box on the Disco2 and fabricate a tray for a second battery. Is it advisable to connect two batteries in parallel, or do I need a fancy separation device??? I'm a little concerned about the alternator having to little resistance.

PepBoys sells small chemical coated felt disks that you place around the battery terminals, under the clamp, that help keep the corosion down. They are about $2.
Or, as I have done with all but one lead, use coper ring terminals on the screw-down posts of most deep-cycle batteries. I don't know who's idea it was to use lead blocks and clamps for connectors, but they are silly.
I connected the second battery in my DII in paralell, and have had no problems whatsoever. You can see my installation at http://www.erikburrows.com click on 'My Truck Batteries'. |

I put those felt disks on the red optima in my truck and it seemed to accelerate the corrosion process. ALmost ate the positive clamp through. It was so eaten up I replaced it.
Could just be a strange chemistry thing about me  but I would just go with straight vaseline.
