The Kärcher 36 V / 2.5 Ah Battery Power exchangeable battery is suitable for use in all devices from the Kärcher 36 V battery platform. Thanks to innovative Real Time Technology with an LCD display, the remaining working time, remaining charging time and charging status - depending on the type of device - are easy to read. Powerful lithium-ion cells provide consistent performance and ensure that the battery does not discharge itself or lose capacity due to frequent partial discharge (memory effect). Thanks to soft but robust housing elements, the battery does not slip on slippery or sloping surfaces.
