All three batteries belong to the STIHL AK System, but the best option depends on the machine, the intensity of the work and how long you want to operate between charges. A larger battery normally provides more working time, although it also adds some weight.
| Battery | Capacity | Best suited to |
|---|---|---|
| STIHL AK 10 | 36V, 2.0Ah, 72Wh | Shorter jobs and lighter compatible tools where low carrying weight is important |
| STIHL AK 20 | 36V, 4.0Ah, 144Wh | A versatile choice for regular garden maintenance and many mid-range AK tools |
| STIHL AK 30 S | 36V, 5.0Ah, 180Wh | Longer working sessions and higher-demand machines requiring maximum battery output |
Important: Although AK batteries are designed for the same battery platform, the recommended battery varies by machine. Some higher-demand products require or strongly recommend the AK 30 S to provide their intended performance. The STIHL MSA 80 C-B, for example, must be used with an AK 30 S. Always check the individual product specification before ordering.
Actual working time varies according to the tool, battery, material being cut, operating conditions, temperature, technique and battery condition. Manufacturer working-time figures should be treated as comparative guidance rather than a guaranteed result for every user.
STIHL AK batteries can be paired with compatible STIHL AL chargers. Choose the charger according to how frequently you use your tools and how quickly you need the battery ready again.
Choose a tool-only machine when you already own the correct STIHL AK battery and a compatible charger. This avoids paying for duplicate batteries and makes it more economical to add further tools to your existing system.
Choose a complete kit when this is your first AK System purchase or when the kit includes a battery that is better suited to the new machine. Check the selected product variation carefully because the included battery and charger can differ between packages.
The STIHL AK System is aimed primarily at homeowners who want capable cordless machinery for regular garden and property maintenance. It provides a strong balance of performance, straightforward operation and battery interchangeability.
The STIHL AP System is better suited to professional users, contractors and customers completing longer or more intensive work. AP tools generally offer a wider selection of professional machines, batteries and carrying options.

The STIHL AK System is a 36V cordless garden-tool platform developed primarily for homeowners. Compatible tools use removable STIHL AK batteries, allowing one battery system to power several types of garden machinery.
AK batteries belong to the same battery platform, but the recommended battery depends on the tool. Lower-capacity batteries may not provide the required output or practical working time in more demanding machines. Check the battery recommendation on each product page before ordering.
The AK 20 is a useful general-purpose battery for many regular garden jobs. The lighter AK 10 can suit shorter work with compatible tools, while the AK 30 S is the stronger choice for longer sessions and higher-demand machines.
It depends on the selected variation. Tool-only versions do not normally include a battery or charger, while complete kits include the items specified in the package description. Check the variation name and package contents before adding the product to your basket.
Working time varies considerably between machines and applications. Grass length, timber diameter, cutting technique, operating temperature, machine settings and battery condition can all affect how long a charge lasts. Refer to the individual product page for model-specific estimates.
No. STIHL AK and AP are different battery systems. Choose batteries and chargers specifically listed as compatible with the machine you are buying.
Yes, many AK machines are designed for regular work in medium-sized and larger domestic gardens. For intensive daily use, commercial work or very large properties, the professional STIHL AP System may be more appropriate.
