Ok, so problem #1.  Randomly I go to crank the truck and there isn't enough juice in the battery to crank.  The odd part is It can happen 2-3 times in a day or none in a week.  And it can happen after 3 minutes of being turned off!  I don't know of a parasite drain that can drain it that fast.  A simple jump or battery charge and it will crank right up.

 

#2 periodically I'll go to unlock using my key fob and it will instantly lock it again, as soon as I unlock, over and over and over. Occasionally it relocks while I'm driving as well... this problem is also periodic.  
 

#3. battery source has tested battery and alternator 3 times and reports them both fine.

 

#4. upon inspection of battery there seems to be a small spill of an oily liquid on it, no clue where it came from but only maybe a teaspoon worth

 

#5 inside the distribution box on top of the battery, one of the small squares of plastic on the corner closest to driver (no terminals here) appears to have been melted... or more so dissolved by this liquid which isn't appearing anywhere else inside distribution box.

 

6. lifting distribution box up reveals scarring and melting / disintegration of bottom of distribution box by this liquid.

 

7. battery source insists that it can not possibly be battery acid, as the acid can't come out of top of battery.

 

any ideas here? I just want it to stop killing battery and leaving me stranded

My moneys on a bad battery. 

That's what I keep saying and thinking. But I bought it at battery source, and I have returned there 4  times now. And every times they Tell me that the battery and alternator test good.  That's where I got them to take the cover off where I noticed the melted still gewey pieces of plastic that you see in the pics.  I had noticed a small amount of liquid on top of battery, and whatever the liquid is seems to be disintegrating the distributor box.  The employees insist that it can't be battery acid and that battery acid can only come out the battery's side overflow ports and not out of the top.  But I can find absolutely no ideas regarding why the battery has this liquid on it or how it got there.  
 

the glob of black left on the sticker of the battery was eating away at the sticker, however there really wasn't any battery damage.  Whatever it is ate thru the distributor cap but not the battery

You might want to have the battery tested by another place thats a little more objective. Alternator is easy, if the truck shows anything over 13volts while running the alternator is good. 

Make sure they "load test" the battery, not just throw a meter on it.

I’ve had a bad battery start my truck and still be bad. To the point of effecting my transmission. It would be in tow-haul mode and not shift out. It was to the point I was checking out rebuilding prices. One day it wouldn’t start. Put a battery in all better. That was on my 02 avalanche.

I took it to the dealership today for the diagnostic apt You guys made for me. They said that if I leave the truck with them today then they will hopefully be able to do the diagnostic next week, but it may be the week after that. Once that's done then they can determine how much longer they will need the vehicle. Unfortunately I don't have another vehicle, I can't just leave my truck here that long. I asked her if it was possible for me to drive it for this upcoming week and drop it off when they were actually able to look at it. She said no, that it has to be on the lot ready when they are ready. So I'm back in the same boat I was earlier, except now wasted a week. And when I had to jump it off yesterday it did something to my dashboard, now those lights don't work at all either.

      PF63 Oil Filters Going Away?

      Some Assembly is Required

      By Grumpy Bear · Posted

      Missing pieces of the Assembly   Detergency vs Solvency   Not the same thing. Detergency is the mechanism that surrounds solid particulates preventing amalgamation. Usually accompanied by a Dispersant whose job it is to keep those encapsulated particles in Suspension. Solvency keeps things that can be dissolved in solution.    Salt is a solid that can be dissolved. Pepper is a solid that cannot be dissolved. A detergent/dispersant is effective on pepper but a solvent is more effective on salt. As long as the solids remain in either state, dissolved or dispersed then they can be be removed with the oil upon change.    How many wranglers does it take to herd cats? Depends on how many cats your herding. How much sponge does it take to soak up water? How much water is there to soak up? Point is most oil blends start with some herding ability and next to zero sponge and recently even fewer wranglers are being sent to do the same job.    So you start with a dozen cowboys and zero cows but at the drive progresses you pick up cows along the way, but not cowboys. At some point you have more cows that the wranglers can handle and some leave the herd. Deposits. And the API has an acceptable number of cows they are willing to let loose. In the ideal world zero is the right number for he rancher but to the butcher....a few lost is fine. This cow is beat to death. Let's move on....   Solvency isn't something oils on the Walmart shelf care about AT ALL. Problem is, you motor does. Fuels driven varnish sticks rings and only a solvent can keep them in check. The bet is that the solids driven portion that plug the expander rings and the oil drain backs and VVT screens and AFM screens will be an issue long before varnish is. Not that it wont be but if they market well enough the consumer can be kept ignorant enough to either believe it is "normal" (A quart in 1 or 2K is normal) OR is kept at bay longer than the first owner is likely to hang on to the unit. Solvency cost money.    Now the OEM's have John Q. Public buffaloed into the belief that the number cows accumulated along the trail is a known and predictable CONSTANT. It isn't. Nor is the rate at which they crossed paths with them. Only the number of wrangles is constant. Or was. Each new generation of oil sees fewer and fewer of them.    So what happens when the number of cowboys is lower (lower TBN) with each seasons trail but the trial is longer (OCI) and the number of cows along that trail continues increase? (Conditions that promote deposits).    For awhile the blenders were on to something. Better bases are harder to degrade (fewer cows) but that was overtaken by a longer trail (OCI) and improved breeding (More cows) while continuing to reduce the cowboy staffing levels (TBN/Aniline #).    Marketing has been successful. We've fired most of the staff, cows breed line bunnies, the trail is ten times longer and we've convinced the boss his ranch is in better shape that it ever was.    That kids is just the cleaning side. The side few pay attention to.
