If the battery appears to be under-performance, or cannot be recharged, please contact the customer service hotline.
Battery is a consumable item. After a period of usage, the working time will decrease gradually. It shows the sign that the battery has started to age. When the working time becomes too short and unable to fulfill the working requirements (unable to clean up the working area effectively) please replace with a new battery.
Prolonged storage without usage may cause the battery to malfunction or die suddenly. Therefore, unless a new battery is needed, it is not recommended to purchase a battery too early for storage.
If the robot is not in use for a longer period of time, it is recommended to take out the battery from the robot. For long term storage, keep the battery level around 60% to ensure battery life. This is a normal feature of Li-ion batteries.
