Bosch GBA18V120 12Ah CORE18V High Power Battery | PROFACTOR Biturbo, AMPShare Ready

Meet the Bosch CORE18V 12 Ah High Power Battery, designed for professionals who demand dependable power and long runtimes from cordless tools. This battery pairs robust capacity with advanced engineering to help you tackle high-demand applications without frequent stops for a recharge.

Why this battery stands out

Compared with the CORE18V 8 Ah, the 12 Ah version delivers equal power and at least 50% more runtime, enabling longer work sessions and reduced downtime between charges. The design includes three layers of enhanced 21700 cells to improve efficiency and heat management.

• Performance and runtime balanced for heavy-duty tasks
• Three-layer 21700 cell stack for improved efficiency
• CoolPack 2.0 cooling technology to keep the pack cooler during use and extend life
• Copper end plates, power rails, and a flexible circuit board to reduce resistance
• Lightweight at 3.04 lb, offering power comparable to larger packs
• High-resolution charge-status indicator for quick checks

In terms of compatibility, the GBA18V120 is designed to pair with Bosch PROFACTOR tools that use BITURBO Brushless Technology, delivering power that meets the demands of cutting, grinding, drilling, and more. It also works with Bosch 18V chargers and the AMPShare System, enabling cross-brand battery management within the AMPShare ecosystem. Note that it is not compatible with non-PROFACTOR tools.

Real-world uses and expectations

Whether you're framing a new build, chipping away at concrete, or finishing trim, this battery is built to sustain longer sessions with consistent output. The light 3.04 lb weight helps reduce fatigue when carried for extended periods, while the CoolPack 2.0 technology helps manage temperature during peak workloads.

• Realistic task scenarios include rotary hammers, grinders, circular saws, and more where sustained performance matters
• AMPShare compatibility makes it easier to manage multiple devices across compatible tools

With Bosch's engineering emphasis on efficiency and durability, this battery aims to deliver reliable power, reduced heat buildup, and clear visibility of remaining runtime through the charge-status indicator. While outcomes can vary with tool and workload, users may experience longer sessions between charges and smoother operation with compatible PROFACTOR equipment.
