Highly durable 18V XL battery with 4.0Ah and COOLPACK technology
Runtime is extended by up to 65% compared to existing 3.0 Ah batteries thanks to high-quality lithium-ion cells
Bosch COOLPACK technology actively manages the temperature of the battery cells and reduces heat development, which is the main cause of damage to every battery
The 18V 4.0Ah battery weighs the same as the existing Bosch 3.0Ah battery and is currently the lightest on the market
