Hello,
In this video, we are performing the battery repair process of the Dreame Vacuum Mop F9 coded robot vacuum cleaner produced by Xiaomi infrastructure. Depending on the duration of use, problems such as sudden shutdown and disconnection of the device have occurred due to the expiration of the batteries. I replaced the battery cells with A28 coded Li-Ion cells, which have a higher capacity than the original and are produced in our country by Aselsan subsidiary Aspilsan. After this change, the robot vacuum cleaner will be able to work longer than before with a capacity reaching 5800mAh. Details of the procedures are in the video.
Enjoy watching.
