Just my .02 cents..


AC DELCO BATTERIES ARE JUNK!! <-- still got a 4 letter word in, not the one I wanted.

My wifes new Suburban at 3 years lost the positive cable, warrantied the battery and the second one did the same thing. Under the hood is spotless except for all the rust and lost paint under the battery case.

NEVER replace your Bonny'* battery with an AC/DELCO! I am extremely worried about loosing all the paint under that back seat. Cranking times have been slowing down so hopefully soon, we're off to get a descent battery.

Whew, glad to get that off my mind.....

ALL Battery Manufactures have their "crappy" battery lines. AC Delco included. I've had good luck with their "Professional" battery line.
Maybe I'm just lucky? :wink2:

I've only had the positive terminal fail on the battery once, and that was about 10 years ago. When I was researching a replacement I asked about that failure as it surprised me. The salesman at the battery shop said that it is caused by the cables being over-tightened. He said the AC-Delco seemed to have a slightly higher failure rate than other branks, but that any of them will fail this way if they're cranked down too hard.

I don't think that over tightening the terminals is what'* causing them to corrode from the inside out... Especially after hearing that a Bonnie battery has also done this. There isn't anything that is present around a bonnie battery.

Anyway, made sure not to overtighten the terminals on mine just in case.

Mine wasn't overtightened either. Of course, once the positive terminal corroded, it was hell to get it off from the post..

Second one was a ACDELCO Professional BTW.. Thought the dealer was doing me a favor.

Good 'ol Walmart Extreme whatever battery in there ever since and I don't even check it.

Bonny get'* the back seat taken out everytime I can remember to do so to check on it.

I'm sorry, I've never had any battery come apart except an ACDELCO so I am leaving it at that.. I just don't trust them. ACDELCO parts are generally junk as it is.. Oil filters such as the AC1218 are junk, take a look inside one. I spent the extra $25 to buy a AC/DELCO Accumulator Drier when rebuilding the AC unit on my '88 GTA only to find the Four Seasons sticker and part number still on the bottom of it which is a $25 cheaper accumulator.. I just don't know.. Pat

Ivory, are you using the Walmart batttery in your Bonne? I looked at Walmart just for the heck of it & they didn't list a replacement battery for 00+ Bonnes.

No, it'* what I have in the wife'* Suburban (and my pickup). Both are that Extreme whatever, the one in my pickup is 4 years and going strong.. Bonny has been cranking a little slower lately, but still have the Delco in it. My guess is that I am off to Sears to get one when it goes. I won't warranty it for another Delco.
