HI guys,
Went through the battery list here and see Sears DieHard 22850080 Group 75/ 86DT is recommended. Could not find that P/N on Sears web. Did find 02850034000 Group 34 Model P-1. Terminals are correct (top only) and correct + & - terminal location. Currently have Optima RedTop Part# 8002-002 Model# 34. I think the model # is the group #? If so, would the DieHard 02850034000 Group 34 be the correct choice? Confused.

BTW, the RedTop has been on the battery tender for a few hours and the LED is still red. Driven 2 days ago so I don't trust it with respect to gauges. After much research I believe start with weak battery is likely culprit. I have done some digital circuit design in the past.

So, buy another RedTop or the 02850034000 DieHard?

Thanks,
Craig

Another update:
The correct Part# for the recommended DieHard is:
P/N 0285008000 Group 75
H=7.9
L=9.5
W=7.875

The original RedTop Part# is 8025-160 Group 25
H=7.69
L=9.38
W=6.75

Diehard Part# 0285003400 Group 34 (I currently have a Group 34 RedTop in my car)
H=7.8
L=10.9
W=6.8

Still confused.

Just make sure it's fresh. This is not a common size. I bought one online, went to pick it up and it was ancient.

Has SpeedHut killed the bad battery theory, or are we still believers? I went SpeedHut and an Amazon on sale optima redtop battery, so far so good.

I got the Diehard. Confusion started with incorrect RedTop installed in my car.

Sears has changed the height of the 75/86, part no 22850035, adding about 1 inch. It no longer fits, or the part number I listed is a replacement for the battery Kendall (Nota4RE) refers to as the go to battery he uses.

I just installed a Sears AGM battery which fits. It is not Platinum, but it was in stock and given my Optima was dead and Passport is showing up tomorrow, I had to have a battery. The Part Number for it is 22850747.

Needless to say today was a day of panic. I drove my car yesterday, and this AM when I went to get it ready for shipment, it was dead, but enough juice to get the door open. Whew!! Thanks to Blake for helping me keep on track with the battery as the issue and for Kendall for returning my call and helping me when the first replacement did not fit!
