Intelligent electronics

STIHL batteries feature an intelligent battery management system - this clever technology gives a constant level of power whether the battery is 100% charged or 1% charged. To find out more about the intelligent electronics in our battery, check out our blog post.



QWhat tools can I use this battery in?

This battery will fit in any of the tools in the AK System, however, it is the recommended battery for the FSA 57 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.

QHow long does it take to charge?

Using the AL 101 charger, you can fully charge this battery in 95 minutes, or you can charge it to 80% in 70 minutes.

QCan I charge it any quicker?

We make two fast chargers, the AL 301 and AL 500. We do not currently sell these online but you can buy these instore, along with other accessories, such as battery storage bags, from our approved STIHL dealers.
