Bosch CORE18V 4.0 Ah Compact Lithium-Ion Battery
Power your Bosch 18V tools through a full work day with the Bosch CORE18V 4.0 Ah Battery. Engineered with next-generation 21700 cell technology and Bosch's CoolPack™ 2.0 thermal management, this battery gives you the runtime and power of a heavy-duty pack in a compact, lightweight form.
Key Features:
- 21700 Cell Technology: Single-layer high-power lithium-ion cells deliver more efficient power-to-weight than older two-layer 4.0 Ah designs.
- 2x Runtime, 60% More Power: Versus the BAT612 18V 2.0 Ah battery — significant headroom for drilling, grinding, cutting, and light chipping tasks.
- CoolPack™ 2.0 Thermal Management: Cools the cells 15% faster than previous-generation CoolPack systems — longer cell lifetime, less downtime waiting to charge.
- Compact & Lightweight: Each battery weighs roughly 1.10 lb — balance and ergonomics that match the latest Bosch tool bodies.
- High-Resolution Charge Indicator: Built-in fuel gauge gives clear remaining-runtime readout before you head into the next cut.
- Bosch 18V System: Compatible with the full Bosch 18V Lithium-Ion tool and charger lineup — drills, drivers, grinders, saws, and more.
- Three-Year Warranty: Bosch 18V batteries carry a three-year limited warranty.
