## Long description

GRUNDER BA-1840C is a rechargeable 18V 4.0Ah battery designed to supply portable power to compatible cordless power tools. It delivers extended runtime compared with lower-capacity packs and is intended for use with 18V tool platforms such as drills, impact drivers and other hand-held equipment that accept the same battery interface. The battery is built to be removed and replaced quickly to minimise downtime during tasks that require continuous operation.
Advantages
The 4.0Ah capacity provides longer operating time per charge, reducing the frequency of battery swaps during medium- to heavy-duty tasks. The 18V voltage rating matches common cordless tool platforms to ensure stable motor performance. The battery is rechargeable, enabling repeated use without disposable cells, and its compact form factor supports easy handling and storage. Designed for quick swap convenience, it supports uninterrupted workflows when paired with an additional charged pack.
Suitable for
Cordless drills and drivers that accept 18V batteries

How to use
Ensure the tool and battery contacts are free of debris and align the battery with the tool’s battery slot. Slide the battery into place until it locks securely; confirm a firm mechanical connection before operating the tool. Charge the battery using a charger compatible with 18V rechargeable packs and follow the charger manufacturer’s instructions.
