Sounds like the power switching logic or the FET's them selves are having problems.

At this point are you up to servicing your own system? Have the correct tools and work area (ESD mat & strap)? Also do you know how to work on SMD devices and work with a sobering iron?

If not then I would go to an Apple Store or authorized service center and have them repair/replace the logic board.

Often this type of problem is due to static discharge around the Mag-Safe connector.

Did you try resetting the SMC? Follow this Apple TN Intel-based Macs: Resetting the System Management Controller (SMC).

Well don't think it's a logic board... Because if I restore the original battery everything is working fine :(

If putting back the old battery works then the replacement battery is defective.
