STIHL AP 20 battery 36 V Li‑ion

If you want reliable cordless power for everyday tree care or landscape maintenance, the STIHL AP 20 battery keeps your AP System tools working smoothly. It delivers consistent performance and clear charge feedback, so you can focus on the job instead of the battery.

Durable and versatile, this 36 V Li‑ion pack suits demanding tasks and is especially well matched to entry-level AP System tools. Four LEDs show the charge level at a glance, and the IPX4 rating means it’s ready for use even in wet weather.

Where it shines in daily work

Ideal for trimming, pruning, blowing or cutting with AP System entry models around gardens and sites. When conditions are damp or the day runs long, the AP 20’s constant output and splash protection help you finish cleanly.

Why it makes work easier

• Constant power: output stays steady as the battery discharges
• Robust build: engineered for a long service life
• Quick status check: 4 LEDs indicate remaining charge
• Weather-ready: IPX4 for splash-water protection

Handling in practice

At 1.3 kg the AP 20 feels well balanced on compatible tools. The battery communicates intelligently with the machine; when both support Power Boost, the tool taps maximum output when tasks demand it. In sustained heavy use, the system can modulate power to protect battery health.
