The Einhell 18 V 2.0 Ah lithium-ion rechargeable battery is a member of the multifunctional and interchangeable battery system from the Power X-Change series from Einhell. The rechargeable battery system can be used universally for all the products from the Power X-Change series. The advantages to the customer are obvious: A single rechargeable battery and a single charger for all tools not only saves significant costs of buying, it also eliminates the untidiness and chaos of having different rechargeable batteries and chargers for each separate tool. The 18V 2.0 Ah Power-X-Change provides maximum safety thanks to Einhell's proactive battery management system. The batteries have a much longer service life, because the charging cycles are adjusted to the specific situation. The high-quality lithium-ion cells are resistant to the self-discharging normally associated with batteries. At the same time the batteries can be recharged at any time without incurring any damage. A three-step LED battery charge status indicator shows the actual charge status at a glance. State-of-the-art components provide permanent monitoring of the parameters during charging. A rubber-coated housing provides excellent impact protection and a firm hold as well. Integrated recessed handles enable the battery to be taken out effortlessly and ergonomically.
