Bosch GBA18V80-2PK 18V CORE18V Lithium-Ion 8Ah High Power Battery, 2-Pack

Meet the Bosch GBA18V80-2PK, a two-pack of CORE18V 8Ah high-power batteries built for demanding cordless work. Each pack stacks two layers of enhanced 21700 cells to balance output with endurance, delivering longer sessions between charges without adding bulk. Designed to complement Bosch 18V tools, these cells aim to sustain momentum through tough tasks, from framing to fastening, with a light feel in your hand.

Power and efficiency you can feel

These packs feature two layers of enhanced 21700 cells to optimize chemical performance and reduce energy loss. When paired with Bosch PROFACTOR tools and BITURBO Brushless technology, you get a level of power that helps you push through heavy tasks with less downtime.

• Delivers about 50% more runtime than the CORE18V 4Ah option, allowing longer sessions between charges.
• Provides over 75% more power compared with the same 4Ah family, suitable for high-demand applications.

CoolPack 2.0 cooling and durable design

CoolPack 2.0 actively cools the pack, which helps maintain performance during long cycles and can contribute to longer overall battery life compared with older designs. Copper end plates, solid power rails, and a flexible circuit board minimize resistance for steadier output and improved efficiency.

• Cooler operation under load helps maintain consistent performance.
• Compact, lightweight form at about 2.14 lbs for comfortable handling and balance.

Compatibility and everyday practicality

The GBA18V80-2PK works with the full Bosch 18V Li-ion line and chargers, and it aligns with the AMPShare system for cross-brand battery management. Optimized to drive Bosch PROFACTOR tools with BITURBO Brushless technology, it helps you approach tasks with cordless confidence in a compact package.

With a high-resolution charge-status indicator, you can quickly gauge remaining runtime at a glance. This dual-pack is designed for 18V tools and a seamless charging experience with Bosch 18V chargers. While outcomes depend on usage, the design aims to support your workflow by supplying substantial power when you need it most.
