Chevrolet Avalanche Starting Issues

I own a 2003 4x4. Two weeks ago I changed out the battery (went bad). I drove it for 5 days, no problems. Then sunday morning the truck was completely dead, I charged it for 12 hrs and was unable to start even after trying to jump start it. I changed out the battery then had the alternator tested, still good but went down quite a bit once a load was put on. I changed out the alternator anyway....ran well for 4 days and now the truck is completely dead again. Has been charging for 8 hrs but still won't start even when jumping from another battery. It won't even turn over.....any ideas?

    My problem was the new battery that was installed by the service center wasn't big enough. Found this out after I replaced the alternator and the batttery twice. Probably doesn't help but there's your answer.

    I have similar issues on my 04 its not that I lose power i just get nothing when I turn the key forward, i have to keep playing with it back and forth then finally about a couple minutes later it will start, it doesnt do it all the time but enough where it is a pain in the [non-permissible content removed].
