    Wrong battery group causing it to go bad?

    Back earlier this year, I bought a battery for my CTS, exact same cranking amps and just about 1/2" taller, but it was a different model- a group size 78 instead of the 101 the CTS normally has. I did this to save $100 on the cost. It's gone bad, and the tech who tested it won't honor the warranty because it's not the battery that's supposed to go in the car. Is this really an issue, do different group sizes charge/discharge differently depending on the vehicle use, or is the store just using a technicality to not honor the warranty? It's the same battery used in same-year Escalades....

    Shouldn't make a wit of difference, sounds like an unfortunate coincidence and that tech is full of it.

    Assuming you got it at some sort of chain store, I would try another location. As Iceman said, the tech's claim is BS. There are plenty of folks who have use the group 78 instead of the group 101 for exactly the reason you stated - more readily available and cheaper.

    You might also try finding the battery company's warranty, see what it says, and bring that as proof that your claim is legit.
    '05 Stealth Grey CTS-V, Hyper Silver Linea Corse Venetos w/Continental ExtremeContact DWs (summer), black Team Dynamics ProRace 1.2 wheels with 275/35-18 R-compounds (track), Hyperblack Rota Torques (winter), KW Variant3s, V2 front brakes, Hotchkis rear sway bar, EPS cam, TEA-ported 243 heads, FAST92 intake w/LS2 TB, JBA Camaro/G8 1-3/4" shorty headers w/JBA cat pipes, Corsa exhaust, UUC motor and tranny mounts, UUC shifter, MAPerformance trailing arms, Specter cradle bushings, etc...

    Thanks for the confirmation! We were able to convince the management to honor the warranty, but it will be the last time I buy a battery from Wal-Mart. I realize Johnson makes them, but this is the second failure in two years.

    glad to hear to hear it worked, it seems to me CTS have some kind of an electrical problem the kills the batteries often (and Group 101 is some kind of a money grab scam IMO) a lot of people are witching over to Group 78 Optimas with good results.

    Mine is failing right now, I went to Wal-Mart to verify the serial number and manufacture date. It's 6 months over the 3 year free replacement. So I'll be looking for the receipt over my weekend. Nevertheless, my battery has a 3 year free replacement and 108 month (9 year) prorated after that. The batteries that are on the shelf at Wal-Mart now has a 5 year warranty, period. Meaning 3 year free replacement and 2 year(24 month) prorated. Talk about a huge difference in warranty period.

    Hopefully I can find the receipt, if not I'll have to eat the lost money.

    Just for your information, when I bought the battery I never told them what it was for. Nor will I tell them what it's for now when I swap batteries. And I haven't step foot in a Wal-Mart in over a year because I am tired of reading horror stories on how they treat their employees. I don't know why it took me so long as I worked for them for maybe 3 months way back in the late 90's. Saw it then too, obviously.

    Ikera, you may be right- I've had a few electrical issues over the past few months that had various mechanics telling me I had a bad starter or a bad alternator, and in the end neither diagnosis was right. I'm out of the warranty period on my car and I don't know if the car is ruining the battery, but if it is, I'd rather buy a $100 battery every three years than spend hundreds on unneeded repair.

    KOT, same here- I worked for them for 5 years in the 90s- not fun then, I can only guess how awful it is now. Even if they weren't so bad, they started shutting down auto centers- There are only a handful of stores now around here with them. My next battery purchase will have more research behind it.
