The K900 battery charger is visually well-designed, which was not to be expected with a charger. I've hung with me in my garage on the wall, so it is readily available when it is needed and does not have to search long in the closets. I have connected my battery with the device, the cable was just enough. I now have the opportunity to have my battery always available for use during the cold season. Diagnostics and battery state of charge, and automatically recharge no problem and very practical. It is einsatzbar for all common battery sizes and thus for me a device that got in my garage a permanent place. A Top battery charger and maintainer, highly recommended to buy.
