If you don't hear any fan or hard disk activity sounds after you turn the computer on, and the sleep light doesn't turn on then Unplug the power adapter from the electrical outlet and from the MacBook, MacBook Air, or MacBook Pro. Wait one minute. Plug it back into the wall first, then to the computer. Make sure the electrical outlet is working by plugging in another device (such as a lamp). When you plug the adapter back into the computer, the power adapter LEDs should light up green or amber.

According to Apple you should never leave your battery in your Mac for extended periods of time without charging it. I think changing the battery again will just result in the same thing and maybe a another "bad Battery."
How old is your computer & battery? When you start you mackbook, when you press button to on the battery any lights come on or blink? If not, the battery is dead. If it's still under warranty, get a new battery.
