I have had the battery load tested and it reads right at 6 volts until the load is applied and then it drops to nothing. Should this be my problem?

Sounds like you found the problem. How old is the battery? They are usually date coded on the top or there may be some documentation in the glove box to give you a hint as to the age of the battery.

I am pretty sure he has had the battery for around 6 to 8 years. It is a red top optimum battery. Is it smart to put that back or does anyone have any suggestions?

If you have charged the battery and the battery voltage drops quickly, as low as your saying, when turning the engine over, the battery is BAD! The load test on the battery confirmed this. The two post on the battery are different sizes. One is larger than the other. Some of the replacement battery cables are not made for + ground so the cable terminals do not fit the battery properly, this may be why the battery cable will not go all the way on to the battery post.

If the Optima was rapidly charged, it will not hold a charge. You can get the proper info on their web site. Glass mat batteries are great, particularly in old cars, but can easily be ruined if handled like the common lead-acid type. Fast charging will shorten the life of the Optima, if it doesn't kill it altogether.

Did you charge the battery on a slow charge for 12 hours before you did the load test? If you did, then the battery is bad. You cannot tell if a battery is bad, until you have tried to charge it. Your test shows a dead battery, it could be because it will not take a charge, but you will not know until you try to charge it.

I have put the battery on the charger and within about 10 minutes the storage light will begin to blink. What does that mean?

Is the strage light on the charger? you will have to look in the charger manual for the reason.

You must live in the state of Denial. CPR on your battery ain't gonna do it. You need to just let it go. It'll be ok, man. All things come to an end. Go buy a new battery !!!!!!

It's not a state of denial. The car owner just passed away 3 weeks ago and it's left up to me to keep this car going like it should and I just want to make the best decisions. I am young and I don't know that much about antique cars but I am willing to learn. It was my girlfriends daddy's car that he completely restored so it is very special to me and sentimental. Thanks for the help.
