WARNING
■ A typical household electric circuit is between
15 and 20 amps. A single STIHL AL 500
charger draws approximately 4.8 amps. A sin‐
gle AL 301 or AL 301-4 charger draws approx‐
imately 4.4 amps and an AL 101 approxi‐
mately 1.3 amps. To reduce the risk of fire
from overloading an electrical circuit:
►Ensure the electrical system is rated to
withstand the expected electrical draw
before charging your battery.
►Charge multiple batteries one at a time or
on separate circuits, unless you know your
circuit can handle the total expected draw
from multiple chargers.
