What is the age of my AC Delco Battery?
 

I just bought my 2000 used and I'm going through all the normal checks. I discovered quickly that the coolant probably hadn't been changed...ever by the looks of it! I addressed that issue yesterday.

I suspect the battery might also be eight years old. If so, then I might replace it in the next few months. How do I tell the age of an AC Delco Battery?

Mine is marked :

AC Delco
78-6YR
Serial Number: 833571
There is also a P followed by a stamp that reads 056N

Edit: Nevermind. I found the answer. If anyone is interested. Looks like my battery was made in May of 2006.

How do I read the warranty date code on my battery?

The warranty date code is located on the top label of the battery. The first character is either a P or S. The next two digits determine the month, the third digit is year and the fourth digit indicates the manufacturing plant. For example, P 094N means the battery was made in September 2004 in the New Brunswick factory.

Deciphering codes on ac delco battery
 

At the price of a battery I personnaly never try to outlast them.The first time you get standed you pay for it just in wasted time and ......Its your call but do the math of the cost per year for reliablity.:thumbs::thumbs:

Since it's just barely 3 years old, I would say that it's still good for another 2-3 years of reliable service. :thumbs:

And most importantly the new batteries don't leak

Thanks for all info---jerry

Not True at all

Well known issue around 98-01 stock ac delco batteries that the positive post would come off on the battery causing a leak.

But then this is almost 2013, just how many of those 12 year old batteries are still in service?:eek:

point being stuff happens

98 Battery
 

I have a 98 and my battery lasted 8 years before I put a new AC Delco in. This battery is still in and working fine. I never used a battery tender on them.

:iagree:

:iagree: That was a design flaw particular to those particular batteries used in those particular years. Those things are long gone. :yesnod:

Just pulled battery out of my 2004. It is a ac delco. I think it is original.
Here is all the info I could find.

cat# 0925
590 cca
86-6yr

Prick punched on top were
4021f54

Stamped on side were
4d16by1e

No other ident can be found----looks goofy to me, help---thanks---
I will be replacing battery anyway. Curiosity getting to me.

:iagree: :iagree:


I store my car during the winter, and I know while it's good for the car, it's an "iffy" deal for the battery. I do put a charger on it for 10-20 minutes each week, usually when I've got the snowblower out to clear the driveway, but still, after 4 years, I usually wind up replacing it....

You my friend need to run right down to the Minimart and buy some LOTO tickets. I too rolled the dice on my 98 Coupe battery and won but,,,,,:eek::leaving: After seeing what happens when they FAIL and leak,,, I would installed another battery. SOON!!! :thumbs:

I believe that the LEAKAGE issue has to do with if the POS and or NEG terminmal was abuse. Some were just plain outright defective and leaked right thru the bolt hole.

You have been warned.

On a positive note,, the battery in my 97 F150 lasted 12 years and was in the truck working fine when I sold it.

Didn't anyone notice that this thread is nearly 5 years old? :eek:

If you are a gambler, trust A/C Delco batterys. If you have had the problem of their leakage you would definetly have the intelligence to use another brand. There are several other gel battery manufactueres. Been there did that.
A word to the wise is sufficient.

I guess not...It floated to the top, and we all jumped on it.

Battery date ???
 

I just bought a 2005 and getting ready to go on Hot Rod Power Tour and don't want any problems. I looked at the AC Delco battery and the date code is S104P. Now I know that is was made in Oct but is it 2004 or 2014? The battery looks new with a little dust on it but so does the rest of the car.

Well, it's about to time to see how all those old batteries are holding up
