Battery Pack for Kärcher electric broom 50

Our Kärcher working again, my wife has your faithful helper again by your side.
The battery fits perfectly on the size, one must, however, the terminal adapted from the positive pole a bit, but it goes easily with a sharp strings Schneider (Large terminal at Kärcher, small on the battery, have the lateral offset of the battery connector slightly shortened and already fits it, you Plus pushes the plug from Kärcher just a little further on the battery Plus plug it).
Otherwise, trouble-free and fast delivery.
I am happy to have me buy any new battery broom, with the battery it is like new again!
Thanks !!
