ALLPRO AP 300 P Battery – Next-Level Power for Professionals (333 Wh, 40 V, Tabless Cell Technology)
The STIHL ALLPRO AP 300 P is the most powerful 40 V battery in the STIHL ALLPRO/AP System, built for maximum performance, long working times and professional-grade durability in the most demanding applications.
Part of the ALLPRO Performance series, it delivers 333 Wh of energy capacity and up to 4.0 kW peak power while weighing just 1.9 kg—ideal for professional users who need extended runtime and consistent high output throughout the working day.
At its core is advanced tabless cell technology. Compared with conventional battery cells, the tabless design improves energy flow, reduces resistance and minimises heat build-up, resulting in higher power output, significantly faster charging and improved battery longevity.
Intelligent STIHL battery management continuously monitors performance to optimise power delivery and help protect against overheating. Constant Power technology maintains consistent output across the entire discharge cycle, so your tool delivers the same level of power whether the battery is fully charged or nearly empty.
Engineered for real working conditions, the AP 300 P is tested under demanding use and designed for up to 3,000 charge cycles* with durability proven against shocks, drops, splashes and repeated daily use. It features an IPX5 water-resistant construction and operates reliably in temperatures from -20°C to +50°C.
Fast charging helps keep downtime to a minimum. When paired with the AL 1802 MO fast mobile outdoor charger, the AP 300 P can reach 80% charge in as little as 9 minutes under optimal conditions**, helping maximise productivity and minimise interruptions.
Compatible with the AL 1802 MO, AL 101, AL 301, AL 301-4 and AL 501 chargers, the ALLPRO AP 300 P maintains forward and backward compatibility across the STIHL ALLPRO/AP System.
 
*Without loss of capacity.
**Time taken to reach 80% charge at ambient/battery temperatures of 25–40°C when used with the AL 1802 MO. Applies to ALLPRO Performance batteries AP 100 P, AP 200 P and AP 300 P(C).
