Rechargeable Li-Ion Battery CAT DXB4 18 V 4000 mAh for Power Tools, Black/Yellow

CAT DXB4 is a rechargeable Li‑Ion battery providing a nominal voltage of 18 V and a capacity of 4000 mAh. Designed for use with compatible power tools, the battery is supplied as a single unit in a black and yellow housing that offers impact-resistant protection and easy visual identification on the job. The compact form factor balances runtime and portability to support extended work sessions and straightforward replacement when performance declines.

Advantages

The battery uses lithium‑ion chemistry for higher energy density and a lower self‑discharge rate compared with many older battery types. Its 4000 mAh capacity delivers extended runtime for prolonged tasks, while the 18 V nominal voltage matches a wide range of cordless power tools. The robust black and yellow casing provides physical protection and helps locate the battery quickly on a busy worksite. The single‑unit supply simplifies inventory and replacement.

How to use

Ensure the power tool is switched off and remove any existing battery before installing the CAT DXB4. Align the battery with the tool's battery slot and push until it locks securely in place. Charge the battery with a compatible charger recommended by the tool manufacturer before first use and whenever the tool indicates low charge. Do not force the battery into incompatible housings and avoid exposing the pack to extreme heat or moisture.

Usage recommendations

To maximize service life, store the battery in a cool, dry place at partial charge if it will not be used for extended periods. Use a charger compatible with 18 V Li‑Ion cells and follow the tool and charger manufacturer guidelines for charging and temperature limits. Inspect the casing regularly for damage and replace the battery if the housing is cracked, swollen, or if performance is significantly reduced.
