  • ONE+ High Energy, 18V, 9.0 Ah
  • Works with all tools in the ONE+ system

A ONE+ High Energy battery of 18V and 9.0 Ah that works with all tools in the ONE+ system. High Energy is a battery technology that increases the power of your existing ONE+ tools through increased energy flow and better power transfer.

The new technology lets the batteries handle higher loads before the overload protection activates, and gives more power per Ah, which means longer run time than previous battery technology. The benefit is greatest for heavier tasks.



What is High Energy and why should you choose it?

High Energy is a battery technology that increases the energy flow and power transfer in the ONE+ system. This means the battery handles higher loads before the overload protection activates, and that each ampere-hour delivers more power — giving both more power and longer run time, especially for demanding work.



How are the battery cells monitored?

The battery uses IntelliCell technology that monitors and balances individual cells. It maximises run time, storage life and safety while giving you more power. A battery indicator easily shows the current charge level, and a robust construction with built-in impact protection provides long durability.
