In this video, I document my process of replacing the 18VDC rechargeable lithium battery on our Gardena Sileno Minimo robot lawn mower. It had gotten stuck while I was ill in bed for a while so the mower slowly drained its charge to a point of no return.
Fortunately, the aftermarket replacement battery from Amazon was much more affordable, shipped quickly, and holds a much longer charge (3.4 Ah). The mower now cuts roughly twice as long between charges.

Wow, "Gardena Sileno" is an impressive video! As someone who has been searching for lawnmowers without perimeter wires, I can't express how thrilled I am to see the Segway Navimow robotic lawnmower. It offers such convenience and efficiency compared to other brands. I highly recommend others to give it a try for its advanced features and hassle-free mowing experience.
Hi, I have some spare 15x 18650 batteries that I want use, but i am not sure about the two yellow wires, where is it connected to the battery?
Warning! I have mower with the same battery (McCulloch ROB S600), which I opened to replace battery cells. It has a BMS (Battery Management System), protecting from over current / over voltage and balancing the cells to prevent failure (which in case of LiPo can be really ugly). I don't see any electronics in the unit you purchased, and therefore would not recommend using it.

Does the app software still have the same daily cut maximum time?
Why did you not just splice a new harness in and use the original location?
Did work ok afterwards?
