Which STIHL Battery System Is Right for You?
STIHL offers a full range of cordless tools to suit every type of user — from occasional gardeners to professional landscapers. With low noise, zero emissions, and no fuel hassle, battery power is the future of outdoor work. But with four different STIHL battery systems to choose from, how do you know which one to pick?
This guide compares the four STIHL platforms — AI Line, AS System, Stihl AK Battery System, and Stihl AP Cordless Range — to help you choose the right one for your needs. We break down how they differ on power, runtime, charging, and compatibility.
AI Line: Simple Tools with Built-In Batteries
For light, occasional garden tasks
The AI Line is STIHL’s entry-level cordless range. Each tool has an integrated 18V battery built in — just plug in the cable to charge. No removable batteries, no extras to buy.
- Quiet and lightweight
- Simple one-plug charging
- Ideal for grass edging, light hedge trimming, and small clean-ups
AS System: Compact Power with Swappable Batteries
For pruning, shaping, and detail work
The AS System gives you more flexibility than the AI Line, with removable AS 2 batteries and a compact charger. It’s still easy to use but better suited to frequent trimming, pruning, and topiary.
- Removable AS 2 battery
- Quick swap and LED charge status
- Only compatible with AS tools and charger
Stihl AK Battery System: More Power for Larger Gardens
For regular garden maintenance and bigger spaces
The AK System features 36V lithium-ion batteries (AK 10, 20, 30) that work across a wide range of garden tools — including mowers, chainsaws, trimmers, and blowers.
- One battery fits all AK tools
- Great for medium to large gardens
- Shares chargers with the Stihl AP Cordless Range
Stihl AP Cordless Range: Heavy-Duty Tools for Professional Use
For landscapers, contractors, and serious workloads
The AP System is built for commercial use. It offers the highest performance, longest runtimes, and widest tool range — with over 30 pro-grade models available. Backpack battery options extend runtime even further.
- 36V batteries: AP 200, AP 300, AP 300 S, AP 500 S
- Interchangeable across the full AP tool range
- Shares chargers with the Stihl AK Battery System (AL 301, AL 500), plus AL 301-4
Battery and Charger Compatibility
Know what works with what
Each system uses its own battery type. AK and AP batteries are not cross-compatible with other systems, but they do share chargers — making it easier to manage tools if you’re using both systems.
- AL 101 – AK only
- AL 301 / AL 500 – Both AK and AP
- AL 301-4 – AP only (multi-slot)
- AS System – Uses its own charger
- AI Line – Built-in batteries with integrated chargers
