Bosch GBA 18V 6.0Ah Professional Li-Ion Battery

Bosch GBA 18V 6.0Ah Battery

The Bosch 18V 6.0Ah Battery provides extended runtime for high-demand cordless applications on professional jobsites. This high-capacity power pack utilizes advanced Lithium-Ion technology to deliver consistent energy output under heavy loads. It is fully compatible with the entire Bosch Professional 18V system, ensuring versatility across various trade tools.

Built for the Job

Contractors and electricians often face downtime when using high-draw tools like grinders, SDS-plus hammers, or circular saws. This 6.0Ah unit addresses that bottleneck by offering significantly more endurance than standard 4.0Ah or 5.0Ah packs. The increased capacity allows for more holes drilled or meters cut per charge, which is critical for productivity in remote areas or high-rise sites where charging stations are not immediately accessible. The rugged housing is engineered to withstand the vibrations and impacts typical of active construction environments.

• Sustained power for heavy-duty timber drilling and metal fabrication tasks.

• Continuous operation for plumbing core-drilling and site prep applications.

• Reliable energy source for site lighting and high-torque fastening.
