Einhell Xchange 18V 2.5Ah Charger and Battery The Einhell XChange 18V 2.5Ah Charger and Battery by Einhell is part of the extensive family of cordless tools in the Power X-Change system for home and garden. The set consists of a 2.5 Ah battery and a fast charger. Thanks to its unique design, its dimensions and weight are relatively small. It stands out not only for its very high-quality lithium-ion cells, but also for the integrated electronics controlling the ABS system, which prevents, among other things, overcharging, overheating, and self-discharge of the battery. This system also allows you to charge the battery in a very short time. The charger ensures the battery doesn't overheat during charging and is charged with the appropriate voltage and current. It will inform you of any damage to the battery, and when it is deeply discharged, it will attempt to revive it and restore it to normal operation. The Power Exchange battery system includes over 75 devices operating on a single battery type. If you already have a battery, you can purchase the remaining devices in the SOLO version – without a battery and charger. Additionally, you can purchase batteries of various capacities (from 2 Ah to 5.2 Ah) and various charger types.
