How do you all get 6.2s to 300K miles

Since they are still new, you might try a battery desulfator to maybe rejuvenate them. it's basically shock therapy for the battery, but it's unlikely they will recover. with the test results showing under 400 cca left in them, I would not try and crank it with them at all. any electronics like the trans controller will be at risk of damage not to mention hanging up the starter bendix where it welds the contacts in the solenoid. you will have a fubar starter on top of it all.

get another set of batteries and keep these to play with or hold on to them and try to warranty them out sometime before the warranty is out.

The condition of those batteries is most likely what took your alternator out. they will take your new shiny chrome one out too!

Im still upset it actually went out like that.
At the very least, the new alternator is more powerful than the old one (100AMPS). Vet discount came in clutch, still, hate how it came to this

Ive been spending the money for AGM, the price gets offset by longer life & I justify by offroading and never worry about stupid angles or putting the rig under water. But AGM prices been going up disproportionately to wet acid.

AC Delco batteries have never disappointed. They outlast any of the other factory batteries I know of.
Focus on the warranty because you will be replacing them again in a few years.

For autozone- google “autozone Devin McLean”. I’ll use them to warranty my stuff previously bought and when there is no other option.

On the alternator install- that list of cleaning contacts is critical. Only thing I saw not mentioned is a wire looked close to the wrapped part of your exhaust. Make sure wires are clear of it.
