Maximum Power and Efficiency in a Lightweight Compact Design

Upgrade your cordless workflow with the Bosch GBA18V40 CORE18V 4Ah Advanced Power Battery, the ultimate solution for professionals who demand high performance without the bulk. Weighing only 1.1 lbs, this battery utilizes the latest 21700 lithium-ion cell technology to deliver a single-layer power source that rivals much heavier, double-layer batteries. It provides up to 2x the runtime and 60% more power than legacy 2Ah models, making it the perfect "Goldilocks" choice for standard to medium-duty applications like drilling into concrete, metal grinding, and repetitive cutting where fatigue is a factor.

Built to last, the GBA18V40 features Bosch’s exclusive CoolPack™ 2.0 technology, a cutting-edge heat management system that pulls heat away from the cells to extend battery life and run-time significantly compared to batteries without this protection. The internal architecture includes copper end plates and power rails to reduce resistance and boost efficiency. Fully compatible with the entire Bosch 18V tool lineup and the multi-brand AMPShare™ System, this battery also includes a high-resolution charge-status indicator, ensuring you never run out of power unexpectedly in the middle of a critical task.

Key Features

  • Compact Powerhouse: Weighs just 1.1 lbs while delivering the performance of heavier batteries, reducing user fatigue during overhead work.
  • Next-Gen Cells: Features a single layer of enhanced 21700 lithium-ion cells for greater energy density and efficiency.
  • CoolPack™ 2.0 Technology: Advanced heat dissipation housing cools the battery faster, extending its overall lifetime.
  • High Efficiency Design: Engineered with copper end plates and power rails to minimize resistance and maximize power delivery.
  • On-Board Fuel Gauge: High-resolution LED charge-status indicator provides clear, instant visibility of remaining runtime.
  • Universal Compatibility: Works seamlessly with all Bosch 18V Lithium-Ion tools, chargers, and the AMPShare™ multi-brand system.
  • Optimized Performance: Delivers 100% more runtime and 60% more power compared to standard BAT612 18V 2Ah batteries.
