Development and testing of STIHL batteries
The outstanding quality and performance of our STIHL batteries is continuously ensured using various test procedures – the most important ones are explained below.
19.05.2025
Overview: Development and tests
- STIHL battery packs and chargers such as the powerful professional STIHL AP 500 S battery are tested in demanding load tests
- Temperature tests validate the system at low and high temperatures
- Safety tests ensure safety in application-related environments, for example with professional outdoor tasks
- Mechanical tests such as the drum test are used to identify potential for mechanical optimisation
Testing in practice at STIHL
STIHL manufactures high-performance battery products in Waiblingen, such as the professional AR 2000 L and AR 3000 L backpack batteries. Product highlights also include the STIHL AP 500 S with its long runtime and first-class performance in all professional outdoor tasks.
The aim of STIHL development is to ensure that all components are optimally coordinated with each other in order to provide the greatest possible performance. The batteries are put through their paces in every development phase to ensure that this requirement is also satisfied in practice.
Examples of tests
Various tests are carried out to ensure the high quality of the end products and to meet the needs of professionals in forestry, landscaping and construction.
From tree and hedge trimming to lawn mowing and leaf removal – the most important thing is the operational performance in order to provide battery power that is suitable for every professional application. Some of the main test procedures are briefly listed below.

The device is cooled down for the temperature test
Temperature tests
For example, the temperature tests involve a test with temperature test benches, whereby the device is cooled down to its minimum operating temperature. This means that the system is ready to start and operate even at low temperatures.
This ensures that there are no obstacles to subsequent professional applications, even in harsher weather conditions.

Safety tests
Safety is a top priority when developing STIHL battery packs and chargers. In order to satisfy this top priority, in many cases, we at STIHL set safety requirements which are higher than the normative requirements.
To this end, we follow systematic methods for fault detection and prevention and also carry out extensive safety tests.

The drum test is one of the mechanical tests
Mechanical tests
The drum test is one of the mechanical tests. It simulates the harsh daily working routine by exposing the battery pack to knocks, blows and vibrations in a rotating drum assembly.
This allows mechanical optimization potentials to be identified in the structure and design.
Outlook for battery development
Our STIHL batteries undergo proven testing procedures such as temperature tests, safety tests and mechanical tests to ensure consistently high quality.
One objective for the future is to offer you even more options in addition to our current battery innovations that simplify professional work – be it through increased performance or fast charging processes.

Simply powerful: STIHL batteries for professionals
In addition, STIHL continues to place a strong emphasis on service life and sustainability when it comes to battery advantages.
Furthermore, the development of STIHL battery packs and powerful chargers, such as charging cabinets, always keeps the requirements of real-life use in mind in order to satisfy the highest professional requirements. For example, the innovative cell design of the AP 500 S battery, which makes optimal use of the volume in the battery pack, is one of the reasons why one of our latest battery innovations offers around 30% more power compared to other batteries.
Important questions and answers
Temperature tests, safety tests and mechanical tests are carried out, among other things, to thoroughly test the battery packs and chargers and to ensure the high product quality and safety.
In a temperature test, a device is cooled down to the minimum operating temperature using a temperature test bench to ensure that it is ready to start and operate even in extreme cold.
During a drum test, the battery pack is subjected to knocks, blows and vibrations in a rotating drum device in order to detect possible mechanical optimization potentials at an early stage.
This ensures the necessary mechanical robustness for professional use of the battery packs.
