Power Laminate technology gives the AP 500 S a significantly increased number of charging cycles compared with a typical STIHL AP battery using cylindrical cells, making it highly suitable for intensive daily professional use.
Technical Details
Why Choose the STIHL AP 500 S?
STIHL is the world's best-selling outdoor power tool brand, and the AP 500 S sits at the top of the AP System battery range specifically for professionals running high-drain tools all day — the Power Laminate cell technology is what allows it to sustain more charge cycles under intensive daily use than the standard cylindrical-cell batteries in the rest of the range. Choose the AP 500 S over a smaller AP battery if you're regularly running high-drain tools like chainsaws or brushcutters for extended periods and need the Power Boost function's peak output.
