Humberg Li-Ion 21 V 2 Ah battery for power tools (5 cells)

The modern Humberg battery with a capacity of 2.0 Ah and a voltage of 21 V is designed for comfortable, intensive work with power tools and garden equipment. Li-Ion technology with no memory effect delivers stable performance, long service life, and practical features such as a LED charge indicator and fast charging.

A reliable power source for your tools: inside the rugged housing there are 5 high-performance cells connected in series, ensuring a steady current supply even under higher load. This makes the battery suitable for both workshop and garden use and helps you handle more demanding tasks without unnecessary downtime.

Practical details make everyday use easier. One-click replacement via the release button speeds up battery swaps, while the non-slip base improves stability and protects the battery body from scuffs. For better work planning, 3 green LEDs indicate the state of charge.

Main advantages:

Li-Ion technology – no memory effect, long cell lifespan
2.0 Ah capacity – suitable for regular and more demanding tasks
Fast charging – full charge from approx. 50 minutes (depending on the charger)
