    It happens because it's being charged.

    It shouldn't be a question of whether or not it heats up; it should be about what the temperature difference is during charging (or use). That requires knowing something about the type and capacity of the battery, whether the laptop and battery is in use during charging, how fast a charging cycle is and how long it's been charging.

    There is a chemical reaction during the charge cycle giving off heat. All batteries do this, so more so than others. The amount of heat given off varies on how rapidly the battery is being charged. This is an issue and always will be an issue. One of the critical things though is that you have make sure that the laptop is cooling properly, and also that the battery is not approaching the end of its lifecycle.

    Is this the original power charging cord? Some after market cords may not be as compliant to the needs of your battery. Like charging too fast or overcharging. Other than that, some heat is normal but it should never get to the point it is to hot to touch.
