18v battery for Festool tools

Why choose Festool batteries and chargers?

Festool is synonymous with top quality in professional tools. Whether you are working on interior construction, woodworking or installation work: Festool machines deliver precision and power. The 18V battery line is designed for maximum performance, with batteries that combine high efficiency with a long service life and perfect connection to the corresponding tool.

Our replacement batteries are a reliable solution when your original battery pack is worn out or you need extra capacity in the workplace. They are CE-certified and tested for safety and compatibility with Festool 18V machines. This allows you to continue working with tools you have already invested in without worries.

Popular models such as the BP 18 Li 3.1 and BP 18 Li 5.2 offer an excellent balance between weight and endurance. Our replacements are technically tailored to these models and deliver constant voltage, even during intensive use. Perfect for long sawing or drilling sessions without loss of performance.

Which battery fits your Festool tool?

Do you use a compact Festool screwdriver? Then the BP 18 Li 3.1 is a common choice due to its low weight. For heavier tools, such as miter saws or combi hammers, replacements for the BP 18 Li 5.2 or BPC 18 offer extra power and longer working time. Thanks to smart electronics, these batteries retain their capacity and protect against overheating or deep discharge.

Are you hesitating between different capacities? Then choose a lower Ah for light work and a higher capacity (such as 5.0Ah) if you want to change less often and need maximum range on location.

Battery chargers and capacity: what suits your working method?

Festool battery chargers are specifically designed for 18V Li-ion battery packs. Our replacement chargers support BP 18 Li and BPC 18 batteries, among others, and are equipped with charge control and temperature protection. For professionals who have to work all day long, fast chargers with active cooling are recommended. Do you work more occasionally? Then a standard charger is a safe and reliable solution.
