Battery Dead Today



I had installed a brand new AC Delco Professional 75-7YR battery back on the 16th of May.The last time I drove the car was June 10th, a trip of about 75 miles and everything worked just fine. Last week, I pulled the car out of the garage to wash it and then back in.
When I installed the new battery, I checked all of the codes, found nothing really bad (all history) and deleted them all.
After trying to start the engine, the battery volts displayed on the DIC was about 9.8 and while the starter solenoid did click, the lights were very dim. When I first opened the driver's door and got in, I heard a buzzing sound that seemed to come from the passenger side of the interior. It went away as soon as I put the key in the ignition and turned it to the RUN position.
After putting my charger on the car for about 30 minutes, it started right up and the DIC and my DVM showed about 14.4v. After letting the car warm up, I shut it off and checked the codes and got these (all showed as history, nothing current):
40-BCM
B0432 Rear Defogger Relay Circuit
B0503 RH DRL Relay Circuit
B0508 LH DRL Relay Circuit
A0-LDCM Left Door Control Module
B2282 Battery #1 Fault
B2284 Battery #2 Fault
A1-RDCM Right Door Control Module
B2283 Battery #1 Fault
B2285 Battery #2 Fault
No other codes.
I drove around for about 20 minutes and kept an eye on the voltage display on the DIC. Initially it showed 14.2-14.3v and gradually dropped to about 13.5v with an occasional low reading of 13.2-13.3v I felt that was too low so I returned home and checked volts at the battery with the engine running using my DVM. The DVM readout showed 13.8v at idle and was steady. Drove around again for 30 minutes and the volts display on the DIC showed a fairly steady 13.7v. This was just below the 13.9v I saw after the fully charged new battery went in.
At this time, it's been 3 1/2 hours since I parked the car and the battery shows 12.36v with my DVM.
Any ideas what I have going on here??

After putting my charger on the car for an hour, it started right up and my DVM showed about 14.4v. I checked the codes again and got these codes (all showed as history, nothing current):
40-BCM
B0432 Rear DEfogger Relay Circuit
B0503 RH DRL Relay Circuit
B0508 LH DRL Relay Circuit
A0-LDCM Left Door Control Module



After cleaning in the garage which took about 40 minutes, I opened the driver's door to remove the top and popped the hatch to set the top in, then closed the hatch and the door. The hood was up all of this time but the lamp went out as is should. So I went to start it again and got nothing more than clicking.
The DIC indicated "Low Voltage" and the dash lights were somewhat dim. Earlier in the morning, I checked battery voltage with my DVM and I got 12.34v. So I decided to check for a current draw and the DVM showed 1.34mA draw
I re-connected the negative cable to the battery and checked volts again. The meter showed a 10.5v initially. I left the leads connected and voltage started to climb and within a minute it was up to 11.7v but when I tried to start the engine again, just clicking. Didn't get a Low Voltage message this time.
There were no noises inside the car when I re-connected the battery.
Any ideas????????
Sorry about the double post....having problems with my high speed connection....

Make sure that the leads at the battery aren't corroded or ozidized.

I bought mine in Colorado Springs, Colorado from Advance Auto ... I am currently in New Mexico where there isn't an Advance Auto. I called their toll-free number and was told to take it to "so-and-so" in this town. I called them and I need to take the battery to them, they will send it to Interstate, they will charge it and tell me what they will do. I've already done that once, and the battery died in about one week sitting in the garage. DO NOT WASTE YOUR $$$$$ ON THIS BATTERY AND THEIR GUARANTEE go to Sears and buy their Platinum battery for $179.00 and have a 4 year 100% replacement and you can go anywhere to have it replaced.
I am so mad at this Optima Red Top I will make it my life mission to post this on every battery posting on this forum and every other Corvette Forum on the web.

I know I am beating a

None of these changed the amount of the observed draw. Checked as many of the grounds as I could get to and everything was clean and shiny. I can't get to G102 as the coolant lines for the intercooler are directly over it. But everything in that area is clean and dry (no indication of a coolant leak anywhere on the intercooler water lines).
G104 has an extra lead attached to it. My car has a Vortech supercharger and a water-cooled intercooler. There is a relay that powers the electric water pump for this system and the groud wire is attached there. Everything is clean. The negative battery cable at the block is clean and tight as is the positive cable. The grounds on the block (#11 and 12 in the FSM pics) are clean and tight. Battery terminal connections are clean and tight.
The wires at G401 (driver's side rear wheelwell) are clean and tight. My car does not have any wires at G402 (passenger side rear wheelwell).
The new battery I have is good; I even swapped batteries from my 87 (same AC Delco 75-7YR Professional Grade) and still get the same current draw.
