Replacement Battery (K55) 4.8 Volt / 3000mAh / Ni-MH battery suitable for Kärcher - brooms (no original spare parts!) K55 - K 50 (Electronics)
Battery holds its charge well. Is not so much that one of the poles is loose, that is, it can be pulled out. One reason for complaint, yes, but as long as he does not feel like I have every time you order something online, to have a complaint.
