Battery replaced and now won’t charge.

Battery was replaced and charged to 100% + 2 hours to calibrate. Have been using MacBook per calibration instructions and MacBook is now at 0% but will no longer charge. Charger worked fine to get battery to 100% but won’t work to continue the calibration. Any ideas?
