Bosch 18V Starter Kit, 2x 5.0Ah Li-Ion Batteries & Charger

Bosch 18V 5.0Ah Starter Set

The Bosch 18V Starter Kit provides high-capacity power for professional cordless tools on demanding job sites. This configuration includes two 5.0Ah Lithium-Ion packs and a rapid charging unit to ensure zero downtime during heavy-duty drilling, cutting, or grinding tasks. It integrates fully with the Bosch Professional 18V system, allowing these batteries to power any tool within the same voltage class manufactured since 2008.

Built for the Job

Contractors and site supervisors rely on this power set for applications requiring extended runtime without the weight of larger 8.0Ah or 12.0Ah units. The 5.0Ah capacity represents the optimal balance for handheld tools like circular saws, SDS-plus hammers, and angle grinders that consume energy rapidly. Because the set includes two units, a technician can keep one on the charging dock while the other remains in the tool. This rotation is essential for high-volume work such as roof framing, subfloor installation, or electrical rough-ins where stopping to wait for a charge is not an option.

• Powering high-torque impact wrenches for automotive or structural steel assembly.

• Continuous operation of cordless dust extractors during masonry drilling.

• Extended runtime for site lighting and ventilation equipment in remote areas.

Product Highlights

The housing material actively dissipates heat from the center to the exterior to prevent cell damage during heavy discharge cycles.

Intelligent Charging Management

• The charger monitors individual cell voltage to prevent overcharging.
• Active air cooling in the dock protects the battery during the fast-charge phase.
• LED fuel gauges on the packs provide instant status updates to the operator.
