Battery pack DeWalt DCB547 18V/54V 9.0Ah & 3.0Ah, 2 pieces

The DeWalt DCB547 battery pack provides two lithium-ion batteries engineered for compatible DeWalt cordless tools. The set contains one high-capacity 9.0Ah unit and one compact 3.0Ah unit that work with 18V and 54V tool platforms, offering a combination of extended runtime and portability. Designed for professionals and DIY users, this pack enables quick battery swaps and flexible power management across a range of cordless equipment.

Advantages

The combination of a 9.0Ah battery for long runtime and a 3.0Ah battery for lighter tasks reduces downtime and lets users balance weight and endurance. Both batteries use lithium-ion chemistry for consistent power delivery and minimal self-discharge. Compatibility with 18V and 54V systems simplifies inventory and tool compatibility for crews and individual users. The pack is intended to improve workflow by enabling fast replacement between charges and offering a compact option when a lighter battery is sufficient.

Suitable for

• Extended runtime work such as drilling, demolition, and continuous fastening with higher-capacity tools
• Lightweight tasks and overhead work where reduced weight is important
• Job sites and mobile crews that require quick battery swaps and mixed-capacity solutions
• DIY projects where both long runtime and compact battery option are useful

Key specifications

• Battery chemistry: Lithium-ion
• Included units: one 9.0Ah battery and one 3.0Ah battery
• Nominal voltages supported: 18V and 54V tool systems
• Intended use: cordless power tools (compatible DeWalt platforms)

How to use

Install the battery into a compatible DeWalt tool or charger by aligning the pack with the tool’s battery port and sliding until it locks. Use the 9.0Ah battery for tasks requiring extended runtime and the 3.0Ah battery when reduced weight or compact size is preferred. Charge batteries in a compatible charger according to the charger manufacturer’s instructions and allow batteries to cool before charging if they are warm from use. Monitor tool performance and swap batteries as needed to maintain consistent power during work.

Recommendations

Store batteries in a cool, dry place and avoid prolonged exposure to extreme heat or cold. Use only DeWalt-compatible chargers and follow the tool and battery safety guidelines; do not disassemble, crush, or expose batteries to fire. For optimal lifespan, avoid full deep discharge when possible and recharge batteries after moderate use.
