The pre-charge current dissipates power in the resistor. Each successive pre-charge adds more power so if the resistor has not cooled between operations then the temperature will rise. Frequent pre-charge operations will cause the temperature of the resistor to increase, potentially to the point where the resistor overheats and fails.

Pre-charge: Once the battery pack has been re-connected or is in a discharged state, pre-charging begins. During pre-charge, the charger starts to safely charge the depleted battery with a low current level that is typically C / 10 (where C is the capacity (in mAh)). As a result of pre-charge, the battery voltage slowly rises.
