Unfortunately Apple's new Battery condition status is very vague. The "Service Recommended" condition may just mean the capacity has dropped below 80% of the Design Capacity or it may indicate a hardware issue with the battery (older versions of macOS made this distinction very clear with several different conditions). You can try running the Apple Diagnostics to see if any hardware issues are detected. If no hardware issues are detected, then you can ignore the "Service Recommended" condition until the battery doesn't work long enough for your needs.
