Notice:

It is not recommended to replace the Ni-Mh battery type with Li-lon and vice versa. The charger on your vacuum cleaner is only adapted for the battery type that came with your vacuum cleaner. We also do not recommend using batteries with a higher capacity/over 3500 mAh/, as this may cause the robot to overheat.
However, the Ni-MH battery has a natural voltage drop and so requires to be energized at all times. Therefore, the vacuum cleaner should be plugged in at all times. The ROOMBA must be in the Home Base (base) or plugged into the power adapter at all times. If this rule is not followed, the battery could become irreversibly damaged. However, the power consumption is very low. By following these rules you will extend the life of the battery and the vacuum cleaner.
