Typical Application:

Power tool batteries, commonly know as cordless tool batteries, have been designed to work with many power tool types e.g. power drills, impact drivers, angle grinders, jigsaws, torches etc. and allow to continue work without having to wait for the current battery to charge. Batteries coming from the same manufacturers and with the same voltage rating as power tools, are typically compatible with each other, eliminating the need of buying dedicated batteries for each tool. Batteries are available in various voltages and capacity.

Power Tool Batteries are commonly used by:
• Builders
• Carpenters
• Mechanics
• Engineers
• Constructors
• Electricians
• Plumbers
• DIYers


How can it be both 18V and 54V?
The battery power output depends on which tool it’s plugged into. On an 18V XR tool, the cells inside the battery pack link in parallel. When fitted to an XR FLEXVOLT tool, the battery cells link in series increasing the voltage to 54V.

Do I need new tools?
No. The XR FLEXVOLT battery is compatible with all DEWALT XR 18V cordless products.

How long does it take to fully charge the battery?
The charging time is only 60 minutes when connected to a fast charger. However, the battery charge time may vary and fully depends on charger capabilities. Please, find a Battery Charge Times document attached above for further information.

Does it come with a charger?
No, batteries aren't supplied with chargers.
