This twin-pack delivers two 18V 5.2Ah Power X-Change PLUS batteries, fully compatible across Einhell's entire cordless tool range. Combine both batteries for 36V operation on demanding tasks, or use individually for extended runtime. Advanced microprocessor-controlled battery management monitors voltage, temperature, and current to optimise performance, safety, and longevity. A 3-step LED indicator displays remaining charge. Reinforced ABS housing resists dust, corrosion, and impact, whilst the rubber grip and trough handle ensure secure handling and tool removal.
