Advanced Battery Technology
STIHL has engineered the AK System batteries with an intelligent battery management system. This clever technology ensures a constant level of power is delivered to the tool, whether the battery is 100% charged or nearing depletion. Unlike other systems that may lose performance as the battery drains, STIHL tools maintain consistently high power. The battery also features a unique cold start function, which protects the cells by warming them in a controlled manner before delivering full power, enabling reliable operation in temperatures as low as -20° Celsius.
Broad Compatibility
This battery is designed to work seamlessly across the entire STIHL AK product line. The AK 30 S delivers full power when used with tools such as the MSA 70 and MSA 80 chainsaws, KMA 80 and FSA 80 grass trimmers, BGA 60 leaf blower, REA 60 pressure washer, and a range of lawn mowers including the RMA 248 T, RMA 253, RMA 443 V, and RMA 448 RV. It is compatible with the AL 101, AL 301, and AL 501 charger units.
