The charger's power output is not sufficient to charge the connected battery within the desired or configured charging time. This is primarily a planning or sizing issue rather than an immediate hardware fault, leading to prolonged charge cycles.
Click steps to track your progress.
Increase the allowed charging time parameter in the charger's settings to accommodate the charger's power and battery capacity.
Consider using a battery charger with a higher power rating that is compatible with the connected battery.
Verify the actual capacity of the battery by checking its nameplate or specifications.
