Equipped with lithium-ion cells, the battery ensures consistent performance. The cells also prevent battery self-discharge as well as loss of capacity due to frequent partial discharge (memory effect). In addition, the remaining running time, charge level and battery capacity are continuously displayed on the integrated LCD display using innovative Real Time Technology. The 18 V/5.0 Ah battery is suitable for use in all devices with the 18 V Kärcher battery platform.
