Their high capacity and durable lithium-ion design make them an excellent choice for professional and demanding applications.

Smart Charging Status Indicator

The batteries include a practical three-LED charge indicator that allows you to easily check the current charge level.

• All three LEDs lit – battery fully charged
• A quick press of the button on the battery displays the current charge level

This intuitive feature allows you to monitor charging without additional devices.

Long Lifespan and Reliable Performance

Each battery provides over 1200 charging cycles, making them a long-lasting and economical alternative to disposable batteries. Designed for intensive use, they are ideal for applications where reliability and endurance are essential.

Advanced lithium-ion technology also eliminates the memory effect, meaning the batteries can be recharged at any time without reducing their usable capacity.
