The Einhell PXC Twin Pack 4.0 Ah battery consists of two universal 18 Volt batteries from the Power X Change range and offers double power in a wide range of uses. The universal batteries of the Power X Change range can be combined with all PXC devices, whether in the field of tools or garden. The lithium-ion cells offer more power with immunity to "battery-common" diseases and resist the battery-standard self-discharge. The battery life is significantly extended thanks to the situationally adjusted charging cycles. Maximum safety is ensured by Einhell's active battery management, and all the parameters of the battery are always monitored by the most modern components. The charging status can be read at a glance: the three-level LED system offers the continuous possibility of charging level control. In addition, a high impact protection and good grip is ensured by the rubberized housing. The batteries can be easily inserted and removed thanks to the adapted grip grooves.
