Today was the first time I went to Wal-Mart for an oil change. Afterwards they gave me a “Battery Test Results” report saying “Battery fails to meet industry accepted standards and should be replaced” The results are: Voltage: 12.79V Measured: 402 CCA Rated: 550 CCA Temperature: …

Putting walmart aside for now, tell us how old the battery is. Vehicle mileage and year? 3.8L V6 engine? IF they measured properly, the battery shows it is/was fully charged. 12.6V is usually the norm. If the charging system is working right, it will likely read around 13-14V when running. When c…

I know, Wal-Mart. I usually go to the dealer but thought I would try W-M. Won’t do that again. Anyway, it has 65xxx miles and is a 3.8L V6 engine. The car’s records indicate it was built in July '05.

Perfectly normal readings for a 4 year old battery. The CCA has dropped a little but that is to be expected. You should be fine for another year unless you park outside in Zero degree weather…

I conclude since you did not mention it no sign of leaking acid was found at the postive terminal side post. For many years (must have been over 5)Delco batteries leaked at this point. Perhaps they have their act together. Sure made a lot of work for me.

Interesting. About three years ago, my original battery on my 2002 Sienna was 5 years old, so I wanted to replace it. I decided to get what seemed like a really good battery, so I got a Delco Professional, thereby wasting lots of money. A few weeks ago, here in Mexico, it failed. Fortunately I foun…

Your battery is fine. Unless you are having any battery related issues, like no-start, etc, I’d just leave it in there until it fails. Unless you’re getting ready to take a trip, and have the money laying around, then a little preventative maintenance won’t hurt anything, the worse it will cause i…

The problem with letting your battery go 'till it fails is that it could also cost you an alternator. Batteries will fail due to heat and vibration … if you seldom use your car, a battery will last for 10 years. Under normal usage (15,000 miles/year)a battery should be replaced every 5 years. There…

I really like the conductance test and this is the test that Wally uses. Tells the batterys ability to take a charge.

There’s nothing wrong with the 12.79 volts except for one thing. That does not tell you what the voltage is when a heavy load is applied; such as a starter motor. The only way to determine this is by load testing the battery and applying a load equal to 3 X the starter current draw. After 15 second…

As far as your CCA goes, I don’t trust any of the tester data. The 12.79 is kind of high because most older batteries don’t go up that high. Most battery testers probably don’t meet any standards. In conclusion: If you aren’t having problems you can disregard the test.
