Bosch Professional GBA 18V 5.0Ah Lithium-ion Battery

The Bosch Professional GBA 18V 5.0Ah Li-Ion Tool Battery is a rechargeable power source designed for Bosch Professional 18V cordless tools. It combines an 18 V output with a 5.0 Ah capacity to support drilling, driving, cutting, and grinding tasks. This lithium-ion pack serves as a high-capacity replacement or spare for tradespeople working within the Bosch 18V system. The cell chemistry provides steady energy delivery for jobs that need longer intervals between charges, and the output remains consistent throughout the discharge cycle. A single battery is a practical backup for reducing downtime on active job sites.

Weighing 620 g, the unit uses a slide-in design for direct insertion into compatible power tools. Lithium-ion technology keeps the self-discharge rate low when the battery is stored between uses. Electronic Cell Protection guards the cells against overload, overheating, and deep discharge to extend service life. A CoolPack heat-management design helps regulate operating temperature during heavy workloads. An integrated charge-level indicator lets operators check remaining energy before starting a job. Together, the thermal and electrical protection features help maintain battery health over an extended period of ownership.

• Charger not included; a separate compatible Bosch Professional 18V charger is required to replenish the cells.
• Recharge indicator present, signalling active charging status.
• Carrying case not included; supplied as a standalone battery unit.
• Black and red housing, matching the standard Bosch Professional tool colour scheme.
• 1 piece per pack, providing a single battery for immediate use.
