It’s a familiar story. After a few years of use, the cordless screwdriver needs charging more often and the cordless vacuum cleaner doesn’t have the energy to collect your crumbs. In my case, it was the robot lawnmower giving up the ghost mid-mow, stubbornly refusing to return to its charging station. The simplest and most costly solution is to order a replacement battery pack. But have you considered just replacing the cells in the battery pack? This approach saves money and reduces waste. Furthermore, you can select replacement cells with a larger capacity than the originals. This isn’t just a repair; it’s an upgrade!
