With the AP 300 Lithium-Ion battery, you can tackle larger landscapes with fewer recharges. The battery features 28% more power than the AP 180, while remaining the same weight (3.8 lbs.). And all STIHL batteries are based on 36-volt Lithium-Ion technology, hitting the “sweet spot” of power and run time. Our batteries are also engineered to last – the AP 300 keeps more than 80% of its battery capacity after 500 charges. It even features specialized voltage monitors and temperature sensors to help ensure optimal operation and a long service life.
