Compatible with the tools in the STIHL COMPACT Cordless Power System, the AK series are lightweight 36 V Lithium-Ion batteries. They feature a charge level indicator on the top with four LEDs so you can see how much charge you have left quickly and easily, at the touch of a button.
There are four LEDS on the battery to indicate the charge level of the battery. Simply press the button to see how much battery life is left.
Stihl battery's feature an intelligent battery management system – this clever technology gives a constant level of power whether the battery is 100% charged or 1% charged.
- The run time for the AK batteries depends on which tool you are using it in
What tools can I use AK batteries in?
These batteries will fit in any of the tools in the COMPACT Cordless System. The AK 10 is the recommended battery for the FSA 56 grass trimmer and the HSA 56 hedge trimmer. The other tools in the range use more power so either the AK 20 or AK 30 batteries, which have a higher capacity, will be more suitable for the other tools.
How long does it take to charge?
Using the AL 101 charger, you can fully charge the AK 10 battery in 80 minutes, or you can charge it to 80% in 55 minutes.
Can I charge it any quicker?
Stihl make two fast chargers, the AL 300 and AL 500 which are compatible with the AK system batteries.
