TOTAL BATTERY BA-1840C 18V 4.0Ah Lithium-Ion Power Tool Battery

When a standard 2.0Ah pack fades mid-task, the TOTAL BATTERY BA-1840C keeps driving. Its 4.0Ah lithium-ion core delivers up to twice the runtime, so you swap batteries less and finish jobs faster. The integrated Battery Management System (BMS) actively guards against overcharge, over-discharge, over-current, over-temperature, and short circuits, while the slide-on design locks securely onto any TOTAL 18V tool. A 3-LED indicator shows remaining charge at a glance, and the rugged ABS housing shrugs off drops and vibration. No memory effect means you can top up anytime without losing capacity.
