The AP 300 battery from STIHL is the answer if you are a professional who needs a weather-resistant battery, long-lasting power, and a good power-to-weight ratio to get the job done. Outdoor work on less-than-ideal days is no problem with the battery’s innovative casing. The AP 300 connects to multiple tools in the AP System, including extended-reach hedge trimmers, pole pruners, chainsaws, and blowers, and it weighs in at just under four pounds. This high-performance battery runs at full speed until the battery is depleted—there is no gradual drop in power. Plus, it retains up to 80 percent of its power, even after 1,200 charging cycles. The AP 300 powers a wide range of professional products, all in a compact design.
