This lithium-ion battery uses advanced cell technology that provides an optimal weight-to-performance ratio, which is immediately noticeable in everyday use - it's not heavy, but offers robust power. An integrated charge indicator on the battery makes it easy to monitor the remaining power, so you'll never be surprised when you run out of power.

With the overheating protection function, you can rest assured even during more demanding tasks or continuous use of the tool, as the battery intelligently regulates temperature and prevents cell damage. This protection means reliable operation even in more intensive conditions where more energy is required in a short time.

The battery is part of the AMPShare Alliance system, which allows compatibility with a wide range of different tools and chargers within partner brands. This means you can use the same battery for multiple types of tools without worrying about needing different models or additional investments. Easy switching between devices saves time – and money.

In addition, the ProCORE line features an optimized internal design that improves discharge efficiency and ensures longer cell life. Carefully selected components, high quality development and an intuitive user experience make this battery one of the most competitive solutions in the world of cordless tools.

It is important to know

When choosing an additional battery, compatibility with your tool is important first, then capacity. Also, keep in mind that the Ah figure helps to judge runtime, but does not in itself tell you how powerful the tool will be.

• The AMPShare Alliance label is useful when verifying a battery system, but check compatibility with your exact tool model before purchasing.
• Choose capacity based on the duration and complexity of the tasks; actual operating time also depends on the tool and work used.
• If you want to reduce the wait between charges, an additional battery can be practical, but it does not guarantee uninterrupted operation by itself.

In practice

🔧 Battery replacement for an existing tool

🟡 Compatible with restrictions - the AMPShare Alliance label is a starting point for verification, but confirm compatibility with your exact tool model before purchasing.

🔋 Extra battery for working between charges

🟢 Very convenient - an extra battery can allow you to continue working while the other one is charging; the actual process depends on your tool and how you work.

🛠️ Longer homework

🟡 Suitable with limitations - the capacity may make sense for more intensive home use, but the runtime is not the same for all tasks and tools.

Answers to frequently asked questions

Does this battery fit every tool with the AMPShare label?

Don't just base your decision on the system name. Check compatibility with your exact tool model before purchasing.

Does more Ah mean the tool will be more powerful?

No. The capacity in Ah is primarily related to the operating time, not the power of the tool itself.

Can I know in advance how long the battery will last?

The exact time cannot be determined solely from the battery capacity. It also depends on the tool and the complexity of the task.
