Battery for Fein tools

Which battery fits your Fein tools?

Fein has been known for decades as a pioneer in power tools for professional use. Whether you work in metalworking, installation technology or renovation, Fein batteries are the reliable energy source behind multi-tools, impact wrenches and angle grinders. Many of these machines use the MultiVolt platform, which offers compatibility between 14.4V and 18V batteries.

Our replacement Li-ion batteries are specially developed for this platform and fit seamlessly on all Fein Select+ tools. Available in capacities from 2Ah to 5Ah, they offer stable voltage, thermal protection and protection against deep discharge. You enjoy maximum working time and minimum downtime, even in demanding applications.

The MultiVolt system enables certain Fein machines to be operated with both 14.4V and 18V batteries. Always check which type your device supports. Our batteries are CE-certified and tested for compatibility, safety and durability – ready for intensive use in the workshop or on site.

Battery chargers and capacity: what suits your working method?

The original Fein chargers, such as the ALG 50 and ALG 80, are known for their charging speed and reliability. Our replacement chargers are fully compatible and offer the same level of safety and functionality. They are suitable for all Fein Li-ion batteries between 12V and 18V.

Do you work on location or with heavier tools? Then a 5Ah battery or an extra fast charger is a smart investment. For short, precise jobs, a 2Ah or 3Ah battery is sufficient. Our chargers are equipped with temperature monitoring and automatic switch-off at full charge, for a longer lifespan of your battery pack.

Frequently asked questions about Fein batteries

Are replacement batteries safe for my Fein tools?

Yes. All our batteries are CE-certified and tested for compatibility with Fein 12V, 14.4V and 18V tools, including MultiVolt machines.

What is the difference between 3Ah and 5Ah in Fein batteries?

The higher the Ah value, the longer you can work with a full battery. A 5Ah battery is ideal for long-lasting and powerful work, such as grinding or sawing.

Can I use a 14.4V battery in an 18V Fein machine?

Only if the device supports MultiVolt. Always check this in the specifications of your tool for optimal performance and safety.
