Time for a new laptop, because that's a logic board failure. I'd try and get a refund on the battery if at all possible, and put that money towards a new laptop. You're looking at probably at least $500US to fix that thing, and I wouldn't be at all surprised if there's some kind of liquid damage you neglected to mention. May not have even happened recently, and you thought you cleaned it up before anything bad happened. If there's any sign of corrosion on the MLB, then the cost to repair goes from borderline uneconomical to more expensive than a new unit at retail.
In any case, given you're probably going to be spending at least 50% of what a new unit would cost, and the fact that you could probably get some kind of scrap value by taking that thing into an Apple store for recycling, I'd say that's probably your best bet here. You probably won't get much for it, maybe $100US, but it's something. I assume they don't care if there's liquid damage or whatever else is wrong, so you may want to swipe the HDD and RAM before you take it in. Leave the battery. Even if you had a screwdriver to get it out, storing it would likely be more trouble than it's worth.
I don't know if it's too late to help you. But, a friend of mine just had this problem. She had to reset the SMC manager.
We followed the procedure at this URL and it fixed the problem right away:

Basically, it's:
- Turn the machine off. Keep it plugged in.
- Hold down shift-control-option and tap the power button. Then release the buttons.
- Wait five seconds.
- Start the computer.
Problem go bye-bye.
Hope this helps!

If you note the OP's post, they quite clearly say that they reset the SMC, as well as replaced the battery. And any time the battery is removed from the unit for a few seconds, the SMC will automatically reset. So when the one battery was removed and the other one put in its place, odds are there was enough of a time lapse to cause the SMC to reset.
We're also talking about a post that's around 4 months old at this point. Odds are the OP is long gone, as there's been no response from them in the intervening time.
In general, while it never hurts to try, I've found that resetting the SMC rarely solves any problems. Same as zapping the PRAM. They're quick and easy things to try, so you may as well on the off chance you get lucky, but I'd put the success rate well under 10%.
This worked perfectly:
Turn off the Mac, make sure it is plugged in. While holding down the shift, control, and option buttons on the left side of the keyboard press the power button once. Wait 5 seconds, release shift, control, and option buttons. Press the power button again to start the Mac.
That is resetting the SMC, which was already stated to have been tried and not work. And you shouldn't need to wait 5 seconds, you should be able to see the magsafe LED react immediately. After that, holding down the buttons isn't really doing anything except potentially triggering the sequence again.
