Longer working time – thanks to 5.0Ah capacity

Ampere-hour rating measures total stored charge; a 5.0Ah pack holds more cumulative energy than lower-capacity 18V packs, allowing more tool run time before a recharge.

Fewer battery swaps during longer jobs, so heavy-demand tools run for extended periods. Planning and productivity improve when fewer interruptions are needed for charging.

Know charge at a glance – with integrated LCD percentage display

On-board LCD reports remaining charge as a percentage, giving a clear state-of-charge readout without removing the pack or guessing based on tool performance.

Plan shift changes or swaps accurately by checking the screen before starting a task. Avoid surprises mid-shift and schedule charging when convenient.

Job-site robustness – with durable construction and weighty build

Reinforced casing and solid assembly are designed to withstand everyday knocks and handling typical on construction sites; user feedback highlights a substantial, non-hollow feel.

A dependable feel and tougher casing reduce the risk of damage from routine drops or rough handling. Expect a battery that stands up to repeated daily use.
