Troubleshooting MacBook Pro's Power:

As for replacing that battery, that may not be necessary. So, try troubleshooting it.

A. Black Mac Screen:

Go Here: If your Mac doesn't Turn On or Start Up - Apple Support

Using External Devices: Try Resetting the SMC and NVRAM, but this time, using an external keyboard. Connect an external monitor and see if you get an output.
