The STIHL AP 20 is an entry-level 36 V, 4.0 Ah Lithium-Ion battery designed to power tools within the versatile STIHL AP System. With an energy capacity of 144 Wh, it offers a fantastic balance of weight and power, making it ideal for a range of lighter gardening and landscaping tasks. It’s a popular choice for domestic users, semi-professionals, and professionals seeking a cost-effective power source for entry-level AP System tools.
Intelligent Power Management
STIHL’s AP System batteries feature an intelligent battery management system. This clever technology ensures a constant level of power is delivered to the tool, whether the battery is at 100% or 1% charge. Unlike other systems that can experience a drop in performance as the battery depletes, STIHL tools maintain consistent power. Furthermore, the POWER BOOST function allows the battery and tool to communicate, providing the maximum possible power for demanding applications while protecting the battery’s longevity.
Built for Durability and Convenience
Designed for real-world conditions, the AP 20 is robust and durable. It is IPX4 rated, certifying it for use in all weather conditions with protection against splashwater from all sides. A practical integrated LED charge indicator with 4 LEDs clearly displays the remaining charge, so you always know when it’s time to recharge. A unique cold start feature protects the cells by warming them in a controlled manner before delivering full power, allowing the battery to function effectively in temperatures as low as -20° Celsius.
Tool Compatibility
The AP 20 is compatible with all tools in the STIHL AP System and can be charged using the AL 101, AL 301, AL 301-4, and AL 501 charger units. The battery’s performance output varies depending on the tool’s power demands:
