OneDNA is a full range of power tools and garden tools based on a single power supply system. With the launch of the OneDNA range of cordless tools, the BLAUPUNKT brand also introduced two models of modern, interchangeable 18V lithium-ion batteries. Model BP1840 with 4.0 Ah capacity. One battery for all home and garden tools. This innovative solution allows all tasks to be carried out while saving time and money.

The batteries are designed for long-term use. Their high capacity enables power tools to run for longer without the need for frequent recharging. This significantly increases productivity. The battery quickly regains full functionality thanks to advanced charging technology.

Both models are equipped with easy-to-read charge status indicators. This facilitates planning work and helps avoid ending up with discharged battery during activities.


Do not discharge the battery to a level where the power tool can no longer operate to ensure longer battery life and more efficient charging. The battery should be recharged as soon as the tool starts to run slower or the low battery indicator comes on.
