[DML] Questionable Optima Battery and voltage problem

["Palatinus, Joe" <jopalatinus@xxxxxxxxxxxx>]

Last Thanksgiving I installed an El-Glo dash kit (from Ryan on the list) and a new optima battery from Pep Boys
 in my daily driver.  I started driving the car and after leaving it for 3-4 days at a time the car battery would be dead, and i could only start it with a jump. I ran the car for a while to charge the battery, but this problem kept repeating. I was convinced that the problem was I had miswired the dash kit somehow and it was somehow draining the battery.  After I would run it for a while it would start right up, so I was under the impression that the battery was still good.  This problem persisted for several months, and I finally decided to take the battery in for a test.  I took the battery to Pep boys and they tested it and within 2 minutes their analyzer said battery bad.  I hadn't even had this battery for a full year!  Luckily Pep Boys exchanged the 130$ battery for free and I have had no problems starting since then.  
I have noticed however that my voltage seems to drop to exceedingly low levels randomly (lower than the first red mark).  (The battery light remains off, and the car still seems to operate fine, but I worry that this is due to the battery being fresh and new.  I have one of 105 amp delco alternators, so I wouldn't immediately suspect the alternator.  If the battery light remains off the alternator should still be ok right?  
Thanks
