Dewalt DCB240-2 20V Max 4.0ah Li-ion Battery 2-pack

Product Description

The DEWALT DCB240-2 is a two-pack of 20V MAX lithium-ion battery packs rated at 4.0 ampere-hours (Ah) each, designed for use with compatible DEWALT 20V MAX cordless power tools. Each battery delivers consistent runtime and is engineered for the demands of trade professionals in electrical, HVAC, plumbing, and general construction. The lithium-ion chemistry maintains charge longer between uses compared to older nickel-based chemistries, and the 4.0 Ah capacity supports extended run time on high-draw tools. Each unit charges in approximately 1 hour when paired with a compatible charger, minimizing downtime on the job site.

This two-pack suits professionals who run multiple cordless tools simultaneously or need a spare battery ready while one charges. Typical applications include jobsite electrical work, mechanical rough-in, plumbing installation, and any trade environment where corded tool access is limited. The 20V MAX platform covers a broad range of DEWALT cordless tools, making these batteries a practical addition to an existing DEWALT kit. The compatible replacement charger is the DEWALT DCB115.

Installation Notes

Battery installation requires no tools — slide the pack into the tool battery receptacle until it clicks into place. Power down and switch off any active tool before swapping batteries. Store and charge batteries at room temperature; avoid charging in extreme heat or cold, which can reduce cell longevity. Disposal of lithium-ion batteries must comply with applicable local regulations and should not be placed in standard waste streams.
