Battery set Bosch Professional 18V 2Ah + 4Ah for power tools

Battery set Bosch Professional 18V 2Ah + 4Ah for power tools includes two Bosch Professional lithium-ion batteries: one 18V 2Ah and one 18V 4Ah. The set is designed for use with compatible Bosch 18V cordless power tools to provide portable power for drilling, fastening and cutting tasks. Intended as a spare pair or to extend runtime on job sites and home projects, the batteries require a compatible Bosch 18V charger for recharging and feature the standard slide-on interface for quick installation.

Advantages

The two-battery combination offers flexibility: the 2Ah cell is compact and lighter for applications requiring less runtime and better mobility, while the 4Ah cell provides longer runtime for more demanding tasks. Both batteries are lithium-ion chemistry, which provides consistent power delivery, low self-discharge and no memory effect. The batteries are compatible with Bosch Professional 18V cordless tools that accept the same battery interface, enabling quick swaps and reduced downtime during work.

Suitable for

• Drilling and screwdriving in wood, metal and masonry
• Indoor and outdoor renovation and repair tasks
• Electrical and plumbing installations requiring portable power
• DIY home projects where both compact and extended runtime batteries are useful
• Professional job sites where a spare battery reduces interruptions

Key specifications

• Nominal voltage: 18 V
• Capacity: 2 Ah and 4 Ah (two separate battery units)
• Battery chemistry: Lithium-ion
• Compatibility: Bosch Professional 18V cordless tool system with matching slide-on interface
• Weight: compact and heavier unit vary due to capacity (typical for 2Ah and 4Ah types)
• Intended use: portable power supply for cordless power tools

How to use

Ensure your Bosch 18V cordless tool accepts the same slide-on battery interface. Before first use, charge each battery with a compatible Bosch 18V charger until the charger indicates full charge. Slide the battery into the tool until it locks in place and switch the tool on according to the tool’s operating instructions. Monitor charge level during extended use and swap the 2Ah and 4Ah units depending on the runtime you need. Recharge depleted batteries in a suitable charger and store them in a dry, cool place when not in use.

Usage recommendations

For best results, use the 2Ah battery for light, short-duration tasks to reduce weight and improve handling, and the 4Ah battery for longer operations. Always use a Bosch-compatible charger, follow the tool and battery safety instructions, avoid deep discharges when possible, and store batteries at moderate temperature to prolong service life.
