Stihl AK System Buyer’s Guide: Which Tool Do You Need?
The AK System is Stihl’s most versatile domestic range. If you are moving away from petrol or corded tools, here is how to choose the right equipment for your Sevenoaks garden:
For Large Lawns: Look at the Stihl RMA 248. It offers a wider cutting width and the power to handle thick grass, especially when paired with the AK 30 battery.
For Wood & Pruning: The Stihl MSA 60 C-B and MSA 70 C-B are exceptionally quiet cordless chainsaws, ideal for cutting firewood in residential areas where noise is a concern.
For Tall Hedges: The Stihl HLA 56 long-reach hedge trimmer allows you to prune high hedges safely from the ground without a ladder.
For Multi-Tasking: The Stihl KMA 80 R KombiEngine allows you to switch between a trimmer, blower, and pole pruner using a single power head.

Stihl AK System: Frequently Asked Questions
Q: Which Stihl AK battery should I choose?
There are three options: AK 10, AK 20, and AK 30. For light trimming, the AK 10 is ideal. However, for chainsaws like the MSA 60 C-B or mowers like the RMA 248, we recommend the AK 20 or AK 30 for maximum runtime and torque.
Q: Can I charge AK batteries with an AP charger?
Yes! One of the best features of the Stihl range is that the AL 301 and AL 500 high-speed chargers work with both AK and AP system batteries, making it easy to upgrade your tool kit later.
Q: What do the flashing LED lights on my Stihl AK battery mean?
Your battery uses four LEDs to communicate its status:
1 LED Flashing Green: The battery is low on charge and needs to be connected to your AL charger.
1 LED Glowing Red: The battery is too hot or too cold. Allow it to reach room temperature (approx. 15°C–20°C).
3 LEDs Glowing/Flashing Red: There is a fault in the tool or the battery is overheated from heavy use.
4 LEDs Flashing Red: The battery has a malfunction and should be brought into our Sevenoaks service centre for a diagnostic check.
Q: Can I leave my AK battery on the charger once it hits 100%?
Yes. Stihl AL 101, AL 301, and AL 500 chargers feature automatic shut-off. Once the battery is fully charged, the charger stops drawing current, so you cannot “overcharge” it. However, for long-term storage, we recommend keeping the battery at 2 LEDs (approx. 40-60% charge).
Q: How do the AK 10, AK 20, and AK 30 S compare in power?
While all three provide the same 36V of power, they differ in energy capacity (Watt-hours).
AK 10 (72Wh): Best for light trimming with the FSA 57.
AK 20 (144Wh): The “all-rounder,” perfect for the MSA 60 chainsaw.
AK 30 S (180Wh): High-capacity cells designed for demanding tools like the RMA 248 mower or BGA 60 blower.
