SCOTT T. I have to agree with Bill J., Johnson Controls seems to have the best line of batteries overall regardless of what sticker they put on them. And I agree that a Die Hard used to be a good battery but I've got a 2 yr old Die Hard Gold that's giving me fits right now. It goes dead in 24 hours, charge it back up or jump & run the car for 3-4 hours and it's good, then it may go dead again in 1-3 days or 1-3 weeks. It's happened three times in the last month. Sears says the battery is fine, and the car has every possible electical option available so it could be something's up with the car too. The alternator is less than a year old from a reputable local rebuilder.
Had to laugh at your comment about the Champion battery. I had a 1000 CCA one I bought from Wally-World. It was my last straw for buying ANYTHING @ W-M or that battery mfg (Ohh I hope they went out of business!). Battery was 26 months old, was free replacement up to 24 months. I went over a speed bump in the high school parking lot just a bit faster than I should have... I normally creep over them about 2 MPH, and I might have been doing 8-10 MPH. About two hours later the truck would barely start, hardly run the heater, wipers, & lights at the same time. The truck spent the night on the battery charger that night. Next morning it even set the truck on fire idling at a gas pump filling it with gas. The battery had suffered a loose plate internally, shorted out, only making 8-9 V and the alternator was charging wide open trying to charge a bad battery, the heavy wire from the alternator to the starter solenoid over-heated and burned up taking the alternaor with it. I towed the truck to my local Ford dealer 5 miles from the house, they tested the Champion battery and it failed every test. I took it back to Wally-World and they charged me $16 for a new OTHER brand battery. I told them I'd be filling a claim for the damage and towing of my truck due to the POS battery. Took SIX WEEKS and several calls to the store manager but they finally sent it off to Minneapolis to be "Tested" I even talked to the guy in the lab who "tested" it and claims it was fine. I told him to install it in HIS car, this was in January, and let me know how many times his car started unassisted with my old battery. He declined my offer. I then told him to throw the thing away. I talked to the Battery Buyer down in Bentonville and he said they had so many problems with that battery MFG and the Champion brand batteries they stopped selling them between the time I bought the battery and the time I had the problem. Anyhow, that was about 18 yrs ago and I haven't spent $50 at W-M since. I can't afford their cheap garbage especially when it tears something else up that was working O-K.
