Compatible with all 18v cordless tools on the Power X Change battery platform, and also suitable for twin-pack use in 36v machines, the Einhell Multi-Ah PXC PLUS is a unique battery with an adjustable capacity: in 6ah mode you get maximum runtime, so you can complete bigger and more demanding jobs on a single charge. However, when you don't need the extra runtime, keeping it in 4ah mode places less stress on the battery and helps to ensure a longer service life. The ABS process-controlled active battery management system has a microprocessor for permanently monitoring the battery parameters. It therefore ensures maximum safety, optimum tool performance, maximum operating time and a maximum service lifetime. The exact, current charge level can be checked on a digital display. The housing is designed to be resistant to dust, corrosion and mechanical influences. The rubber coating provides high impact protection for the battery along with a good grip.
