You do not say what exact Mac /model /year /size /retina /TouchBar is this

what exact macOS you are currently running?

See if you qualify:

13-inch MacBook Pro (non Touch Bar) Battery Replacement Program- October 2016 and October 2017

15-inch MacBook Pro Battery Recall Program- September 2015 and February 2017

What is the condition of the battery—hold the Option key and click open the batt icon in the upper right menu bar.

Anything but <Condition : Good >needs to be serviced.
