The BMS slowly reduces the charge going into the battery as the battery ages based on a formula that is meant to stop the battery from being boiled because generally old batteries can't take as much charge as new batteries. Fitting a new battery without telling the monitor that the battery is new will cause the new battery to not be charged to the extent that it would be if the BMS was told it was a new battery which can lead to the battery prematurely becoming run-down. If you had your own tool you could try resetting the BMS to see if it overcame the low battery condition before resorting to fitting a new battery.
