How To Choose a Cordless Product 

  • How large is the property?
  • What type of work will you need to do?
  • Will you need just one unit, or a variety of products to get the job done?
  • How often will you use your unit(s)?

Stihl Battery Overview (Stihl Lightning Battery System – AI/AK/AP Series)

  • Battery technology has advanced to the point where battery-operated products are a cost-effective alternative to gas-powered, while still offering run times and power that are comparable
  • Research suggests that by 2025 battery-powered outdoor power equipment will surpass gas-powered
  • Batteries cannot be overcharged – charges automatically switch off
  • There is a temperature sensor to protect batteries from overcharging (but don’t store batteries in charger)
  • On average, it only costs 5 cents to charge a fully depleted battery to 100%!!
  • When inserting the battery, there is a double click – the first click connects the battery to the machine, the 2nd click engages the battery to power the machine
  • Battery Management System (LED Status signals):
    • 1 green LED – 25% charged
    • LED lights light up as battery charges – once fully charged the battery/charger are shut down
    • 1 glowing red LED – too hot/too cold – always try to keep batteries from extreme temps
    • 3 glowing red LED’s – motor is too hot (maybe debris or a dull chain has been causing stress on motor)
    • 3 flashing red LED’s – internal battery issue
    • 4 flashing red LED’s – internal battery issue – battery needs to be replaced (if integrated battery, the electronics would need to be replaced)

The Facts Behind Battery Voltage

  • Common misconception to think that the rated voltage of a lithium-ion battery strictly equates to power (true energy capacity of a battery is actually measured by watt-hours (Wg)) — Wh = Voltage x amp hours
  • High voltage = high motor torque/high power
  • The capacity of the battery (amp hours or ah) = running time

STIHL Lightning Battery Line – AI Series

For smaller projects, choose the easy, all-in-one convenience of the STIHL AI Battery Series. AI products feature an integrated battery that plugs right into the wall. This series is ideally suited for quick tasks around smaller yards and condominiums.

  • Designed for smaller properties
  • Integrated battery

AK Series

Exceptional power meets exceptional value. The AK Battery Series has everything you need to get working. This series is ideally suited for frequent use around suburban yards.

Troubleshooting Non-Working AK Units

  • Inspect all battery contacts aren’t damaged and free from corrosion
  • Inspect air intake for damage/possible debree contacting fan
  • Listen for audible click when squeezing the trigger – will verify switch is mechanically working
  • Depress battery status button to light up LED’s to see the status of the battery
  • If none of these are issues, you will need to open up the unit for further inspection (test motor with tester by connecting the red and black motor leads – correct reading should be between 0.2 and 0.8 Ohms) – otherwise motor will need to be replaced
