- Steel auger and housing for durability
- Electric chute rotation with joystick control
- Push-button start (no pull cord)
- Variable speed drive for precision control
Battery System
Battery management is critical for the SNT2405. Cold weather significantly affects lithium battery performance, making proper handling essential.
Won’t Power On
When the snowblower doesn’t respond to the start button, work through these checks.
Safety and connection verification:
- Both batteries fully inserted - Each should click into place
- Both batteries charged - Check LED gauges on batteries
- Safety key installed - Required for operation
- Control lever at STOP - Safety interlock prevents starting with controls engaged
If still no power:
- Remove both batteries, wait 30 seconds, reinstall firmly
- Clean all battery contacts with dry cloth
- Try known-good batteries if available
- Check for visible damage to battery slots
- Verify safety key is properly seated
The SNT2405 requires both battery slots to have batteries installed (or slot covers) to operate. A single battery must be in the correct slot.
Understanding Battery Options
| Battery | Capacity | Weight | Runtime (Light Snow) | Runtime (Heavy Snow) |
|---|---|---|---|---|
| BA2800T | 5.0Ah | 2.4 lbs | 25-35 min | 15-20 min |
| BA4200T | 7.5Ah | 3.2 lbs | 45-60 min | 25-35 min |
| BA5600T | 10.0Ah | 4.0 lbs | 60-80 min | 35-50 min |
Recommended configuration: Two BA4200T (7.5Ah) batteries provide the best balance of runtime, weight and cost for most users. Serious snow country may want BA5600T (10Ah) batteries.

Short Runtime
If the snowblower doesn’t last as long as expected, several factors may be involved.
Normal runtime reducers:
- Snow density - Wet, heavy snow draws more power than fluffy powder
- Snow depth - Deep snow requires more passes or slower speed
- Cold temperature - Expect 30-50% capacity reduction below 20°F
- Battery age - Lithium batteries lose capacity over time
- Single battery operation - Dramatically reduces available power
Abnormal runtime issues:
- One battery not working - Check that both batteries show discharge during use
- Damaged cells - Battery dropped or exposed to water
- Charger malfunction - Battery not reaching full charge
Battery Won’t Charge
When batteries won’t accept a charge, troubleshoot methodically.
Charging diagnostics:
- Verify outlet has power (test with another device)
- Check charger LED response when battery is inserted
- Clean all contacts with isopropyl alcohol
- Ensure battery temperature is above 32°F (freezing)
EGO charger LED meanings:
- Green solid = Fully charged
- Green/Amber alternating = Charging
- Red = Error or temperature issue
- No light = No power or no battery
Critical: EGO batteries will not charge when frozen. Bring batteries indoors and let them reach room temperature before charging. This can take 1-2 hours for a very cold battery.
Motor Problems
The SNT2405 uses two separate brushless motors - one for the auger/impeller and one for the drive system.
Auger Motor Won’t Run
When the auger doesn’t engage with the control lever:
Systematic diagnosis:
- Both batteries charged and properly seated
- Auger control lever fully engaged
- Safety key installed
- No error indicators on display (if equipped)
If auger clicks but doesn’t spin:
- Ice or debris jamming auger (most common)
- Thermal protection activated
- Motor controller fault
Clearing an auger jam:
- Release all controls immediately
- Remove both batteries for safety
- Use the included clearing tool (never hands!)
- Clear ice or debris from auger housing
- Reinstall batteries and test
Drive Motor Won’t Work
When the snowblower won’t move under its own power:
Checks:
- Speed selector not at zero position
- Drive lever engaged
- Both batteries adequately charged
- Wheels not frozen to ground
If motor hums but wheels don’t turn:
- Wheels frozen to surface (common after sitting)
- Drive mechanism issue requiring service
Motors Stall Under Load
The motors stopping during operation indicates the system is protecting itself.
Common causes:
- Snow too heavy or deep - Take smaller bites, slow down
- Low battery - Insufficient power for demand
- Auger jam - Ice or debris blocking rotation
- Thermal protection - Motors overheated from heavy use
Thermal protection recovery:
- Stop and release all controls
- Wait 10-15 minutes for cooling
- Resume with lighter load (smaller bite, slower speed)
- Consider letting very heavy snow accumulation settle before clearing
Always use the clearing tool, never your hands, to remove jams
Reduced Power
If motors run but seem weak:
Troubleshooting steps:
- Verify both batteries are fully charged
- Confirm both batteries are working (both should discharge during use)
- Clear any partial jams in auger housing
- Reduce bite depth - don’t try to clear full-depth heavy snow in one pass
- Check if thermal protection is limiting power after heavy use
Auger System
The two-stage design uses a steel auger to collect snow and feed it to a high-speed impeller for throwing.
Auger Won’t Turn
When the auger doesn’t rotate with the lever engaged:
Diagnosis sequence:
- Auger lever fully engaged - Must be held firmly
- No ice jam - Most common cause of non-rotation
- Motor engaging - Listen for motor sound
- Shear protection - Some two-stage units have shear pins or torque limiters
Clearing Auger Jams
Jams are common, especially with wet snow. Clear them safely.
Proper clearing procedure:
- Release auger control immediately
- Turn off the machine
- Remove both batteries
- Use the included clearing tool to break up ice and remove debris
- Never put hands in the auger housing - even with batteries removed, stored energy can cause rotation
- Reinstall batteries and test
Preventing jams:
- Clear snow before it gets too deep
- Don’t overload the machine with wet, heavy snow
- Slow down in heavy conditions
- Apply silicone spray to chute and housing periodically
Weak Throwing Distance
Snow not throwing as far as expected can have several causes.
Throwing distance factors:
- Snow moisture content - Wet snow is heavier and doesn’t throw as far
- Ground speed - Moving too fast overloads the impeller
- Chute obstruction - Ice buildup restricts flow
- Low battery - Reduced impeller speed
- Chute angle - Adjust deflector for optimal arc
Improving throwing distance:
- Slow down in heavy/wet snow
- Keep chute clear of ice buildup
- Ensure batteries are well-charged
- Adjust deflector angle for conditions
Drive and Controls
Won’t Move Forward/Reverse
When the drive system doesn’t respond:
Systematic diagnosis:
- Drive lever engaged - Must be held to move
- Speed selector position - Not at zero
- Batteries charged - Drive motor needs power
- Wheels frozen - Common after sitting in cold
Frozen wheels: Rock the machine or pour warm (not hot) water around wheel bases to free them.
Electric Chute Control
The SNT2405 uses a joystick for chute rotation and deflector angle.
Chute problems:
- Joystick not responding - Check for ice around mechanism
- Chute rotates slowly - Low battery or cold affecting motor
- Chute stuck - Ice buildup in rotation mechanism
Preventing chute freeze-up:
- Apply silicone spray to chute before use
- Rotate chute periodically during use to prevent ice bonding
- Clear snow from chute area before storage
LED Headlights
If headlights don’t work:
- Check light switch position
- Verify adequate battery charge
- LED failure is rare but possible
- Wiring connection issue
Cold Weather Operation
Cold weather is the biggest challenge for battery snowblowers. Managing batteries properly is essential for good performance.
Battery Performance in Cold
Lithium batteries lose significant capacity in cold temperatures.
| Temperature | Approximate Capacity |
|---|---|
| 70°F | 100% |
| 40°F | 85-90% |
| 20°F | 60-70% |
| 0°F | 40-50% |
| -10°F | 30-40% |
Cold Weather Battery Strategy
Before clearing:
- Store batteries indoors at room temperature
- Insert batteries just before starting
- Keep spare batteries warming inside
During clearing:
- Swap to warm batteries when first set depletes
- Bring depleted batteries inside immediately
- Rotate between sets for extended sessions
After clearing:
- Remove batteries immediately
- Bring indoors before charging
- Don’t charge frozen batteries
Store batteries indoors and install just before clearing for best cold-weather performance
Cold Weather Operating Tips
- Clear snow before it gets too deep - easier on batteries and machine
- Don’t force through heavy drifts - take multiple passes
- Allow motors to cool between heavy sessions
- Keep discharge chute clear of ice buildup
- Move at moderate pace - rushing increases power demand

Frequently Asked Questions
Can battery snowblowers really handle serious snow?
The EGO SNT2405 handles most residential conditions effectively - typical snowfalls, average driveway sizes, and moderate accumulation. For extreme snowfall (24”+), extended driveways (100’+), or commercial use, gas still has advantages in unlimited runtime. But for the majority of homeowners, the SNT2405 clears driveways just fine.
How does it compare to gas two-stage snowblowers?
Advantages over gas:
- Push-button start (huge benefit in cold weather)
- No fuel to store, mix, or go bad
- Quieter operation (won’t wake neighbors at 6 AM)
- No carburetor issues after storage
- Lower maintenance overall
Gas advantages:
- Unlimited runtime (just add fuel)
- Better for extreme cold (no battery capacity loss)
- Lower upfront cost for comparable clearing width
- More powerful for very heavy, wet snow
Is cold weather really that big of a problem?
Yes, it’s the main limitation. Expect 30-50% capacity loss below 20°F. The solution is battery management - keep batteries warm until needed, rotate between sets, and bring depleted batteries inside immediately. Most users clear their driveway before batteries deplete even in cold weather.
Can I use just one battery?
Technically yes, but performance drops significantly. The machine is designed for two batteries working together. With one battery, expect reduced auger speed, slower throwing, and much shorter runtime. Keep both slots filled for best results.
How many driveways can I clear on a charge?
With two 7.5Ah batteries in moderate conditions, expect to clear a typical two-car driveway (20’ x 50’) 2-3 times, or a longer driveway once. Heavy, wet snow or very cold temperatures reduce this. Having spare batteries charging inside lets you handle any residential clearing needs.
Why does my snowblower seem weaker than when new?
Most commonly, cold batteries. Make sure batteries are warm before use. Also check that both batteries are working (both should discharge during use). Over time, battery capacity does decrease - if batteries are 3+ years old with heavy use, capacity loss may be noticeable.
