I bought a DuraLast Gold H8 (H8-DLG) from Autozone and I've already had it replaced twice in the last 6 months, so I'm wondering if it's even the right battery and if there's something better or it's a car problem.

When I connect it to my Shumacher battery charger, it read 0.0 and doesn't change. From my understanding, that means it's completely dead with no hopes of being charged.

you could have a parastic drain .. but usually desnt kill the battery totally. id be checking for that tho.
My interstate battery has lasted allmost 10 years now and shows no signs of slowing down .

+1. I know I have a parasitic drain on my 3.2's battery with no time to investigate. So, I keep a trickle charge (2amp) on my Red Optima until I have time to investigate. I does not sound like the battery is the issue.

For a parasitic drain, check the door switch. You can test this with the interior light. If should turn off when the door is closed (if set in the appropriate position). If the switch gets stuck, some circuits will remain active after parking the car. It took me a while to figure this out. I cleaned and lubricated the switch, and everything works great now.

Have you checked the alternator and voltage regulator to make sure they are operating properly?

Either you charger is defective or the battery's electrolyte has completely boiled off.

Latter is generally the result of overcharging but that is almost always accompanied by a very noticeable sewer-like odor.

That's exactly what I've been experiencing. My interior light hasn't been turning off when I shut the door so I manually switched them off, but I never put the pieces together and assumed they were unrelated...

What did you use to clean and lubricated them?! Carb cleaner and WD40?

Something like that. Whatever lube I had handy. It's a short-term fix. Long-term is to replace the switch. Like Red Green says, "It's only temporary. Unless it works."

Well, it started flickering again, so I sprayed WD-40 on it now doesn't work at all.

I tried to remove the switch with the socket wrench, but it just kept spinning and wouldn't come out. Is there some kind of trick to getting this thing out?

My parasite drain was a faulty trunk light switch that never turned off. Discovered only after a new battery and Battery Tender.
