AK Battery System
Blower Won’t Turn On
Check:
- Battery fully inserted (push until click)
- Battery LED shows charge
- Trigger depressed
If no power:
- Remove battery, wait 30 seconds, reinstall
- Clean contacts with dry cloth
- Try known-good AK battery
- Check for debris in slot
Understanding Battery LEDs
On battery:
- 4 lights = 75-100%
- 3 lights = 50-75%
- 2 lights = 25-50%
- 1 light = 0-25%
- Flashing = error or temperature issue
Short Runtime
Expected runtime with AK 30 (7.2Ah):
- BGA 60: 35-45 minutes (variable speed)
- BGA 86: 25-35 minutes (variable speed)
If runtime is drastically reduced:
- High speed continuous use
- Battery age/degradation
- Cold temperatures
- Battery cell imbalance
Battery Not Charging
AL charger troubleshooting:
- Power outlet confirmed working
- LED responds when battery inserted
- Contacts clean
- Battery at room temperature
Error indicators require Stihl dealer diagnosis for specific fault codes.

Frequently Asked Questions
How does Stihl BGA compare to EGO blowers?
Both are quality options with different strengths. Stihl offers excellent build quality, extensive dealer network, and strong resale value. EGO typically delivers more raw CFM for the price and has longer battery runtime. Stihl batteries work across the entire AK tool line, which is valuable if you’re building a cordless system. Choose Stihl if dealer support and build quality matter most; choose EGO for maximum power per dollar.
Can I use AP batteries in BGA 60/86?
No. The BGA 57, BGA 60, and BGA 86 use the AK battery system exclusively. The larger BGA 100 and professional-grade equipment use the separate AP battery system. The two systems are not cross-compatible - different voltages and physical connections.
Is the BGA 86 enough for a large yard?
For most residential properties up to an acre, yes. The BGA 86’s 518 CFM handles typical leaf clearing effectively. Very large properties (multiple acres) or heavy commercial use may need multiple batteries for a single session, or you might consider gas equipment for unlimited runtime. Having a spare AK 30 battery eliminates runtime concerns for most users.
Why buy Stihl over cheaper brands?
Several factors justify Stihl’s premium pricing:
- Build quality - Stihl equipment is built to last and withstand professional use
- Dealer network - Authorized dealers provide expert service and genuine parts
- Resale value - Stihl equipment holds value better than budget brands
- Battery ecosystem - AK batteries work across many tools
- Longevity - These blowers last 10+ years with proper care
How long do AK batteries last?
Expect 500+ charge cycles or 5-8 years of typical residential use. Proper storage (partial charge, room temperature) extends battery lifespan. Avoid leaving batteries fully discharged for extended periods.
Can I use the BGA 86 in wet conditions?
Not recommended. While the blower has reasonable weather resistance, water can damage electronics and create safety hazards. Wait for dry conditions or use the blower to clear surfaces after rain stops.
The Stihl BGA 86 delivers professional-grade build quality in a battery-powered package
