*Initial no-load voltage peaks at 20V; nominal voltage under typical load is 18V.
Why Choose 20V ECOSHARP®?
- Lightweight and easy to handle
- Ideal for smaller tools and shorter jobs
- Fade-free power with no memory effect
- Designed specifically for 20V tools
The 20V platform is a great choice for customers looking for simple, efficient power in a compact format.
Understanding Amp-Hour (Ah) Ratings
Amp-hour (Ah) ratings indicate how long a battery can run, not how powerful it is.
- Higher Ah = longer runtime
- Voltage must always match your tool
- You can safely use higher-Ah batteries within the same platform
Example:
A 24V tool can use 2.0-Ah, 4.0-Ah, or 5.0-Ah 24V IONMAX® batteries.
Battery Charge Indicators
Snow Joe + Sun Joe batteries include built-in LED charge indicators that show the remaining battery level at a glance. The number of indicator lights varies by battery model.
3-Stage LED Display

(Common on many 24V IONMAX® batteries)
3 lights on: High charge
2 lights on: Medium charge
1 light on: Low charge — recharge recommended
4-Stage LED Display

(Common on 20V ECOSHARP® (X20) batteries)
4 lights on: 100% charge
3 lights on: ~75% charge
2 lights on: ~50% charge
1 light on: ~25% charge
Charging & Temperature Tips
Lithium-ion batteries are sensitive to extreme temperatures.
If a Battery Is Too Cold or Too Hot
- Batteries that are very cold or hot may not charge or operate
- Allow the battery to rest indoors for 30–60 minutes before charging or using
- This helps protect the battery and extend its lifespan
General Charging Tips
- Use only the charger designed for your battery platform
- Charge batteries indoors in a dry location
- Batteries do not need to be fully discharged before charging
Important Compatibility Information
Although all Snow Joe + Sun Joe batteries use lithium-ion technology, battery platforms are not interchangeable.
- 24V batteries work only with 24V IONMAX® tools
- 20V batteries work only with 20V ECOSHARP® tools
- Legacy platforms (20V ION, 40V, 100V) work only with tools designed for those systems
Always match the voltage and platform printed on your tool.
How to Choose the Right Battery
To select the correct battery:
- Check the voltage listed on your tool
- Match it to your original battery
- Choose the Ah rating based on how long you want to work
