Lenovo G550 battery problem

[Little Marine]

I have a Lenovo G550 with Windows 7 Home premium. The battery will not charge. If I plug in the charger the laptop won'r come on unless I take the battery out. If I put the battery back in the laptop shuts down. The battery I have is new.

A new battery should not do that. If it was charged.
Contact whoever sold  the battery.
Also, read this simple guide. The battery must be fully charged before you turn on the laptop. Do not attempt to use  the laptop on a new battery that is not fully charge for first time use.
General reference:
How to Replace Your Laptop Battery
That same information is somewhere in the laptop  documentation.

Is the battery a original Lenovo?
Or a "equivalent" third party battery?

Some of the aftermarket one's have problems like you are having.

Also the battery it came with should have still worked or was it showing the same symptoms ?
