Endless battery life and powerful performance: The 2.5 Ah Kärcher Battery Power rechargeable battery scores points with its simple release mechanism, which enables effortless and quick insertion and removal - without any tools. For maximum flexibility during use, the device runtime can be extended as required with additional batteries. The contact system and IPX4 splash water protection guarantee safe use, even in devices with higher currents. The high-quality lithium-ion cells impress with their constant performance and prevent both self-discharge and the memory effect (loss of capacity due to frequent partial discharge). Another advantage is the soft-touch area for optimum handling without slipping during battery changes. Sustainable thanks to battery sharing: The 2.5 Ah Kärcher Battery Power exchangeable battery is suitable for all 4 V Kärcher Battery Power devices with an exchangeable battery system - even for devices with 2 batteries.
