Sun Joe cordless trimmers are available with different battery systems and package configurations.
Before choosing a replacement battery, first check the complete model number and battery system shown on your trimmer.
Which Battery System Does My Trimmer Use?
| Battery System | Example | Battery Guidance |
|---|---|---|
| 24V IONMAX | 24V-ST14 and 24V-SB10 Series cordless trimmers | Use a compatible battery from the 24V IONMAX system that is specified for your exact model. |
| 20V ECOSHARP X20 | X20 Cordless Trimmer + Edger | Use the 20V ECOSHARP battery and charger specified for the X20 trimmer. |
Check the battery system, not only the amp-hour rating.
The 24V IONMAX guidance in this article applies to trimmers designed for the 24V IONMAX system. The X20 Trimmer + Edger uses the separate 20V ECOSHARP system.
Which Batteries Work with 24V IONMAX Trimmers?
Current Sun Joe cordless trimmers such as the 24V-ST14 and 24V-SB10 Series are designed for the 24V IONMAX battery system.
The 24V-SB10 tool-only operator's manual specifically identifies the trimmer as compatible with the 24V battery and charger system.
Different battery capacities can provide different runtimes. A higher or lower amp-hour rating can change how long the trimmer operates before the battery needs to be recharged.
Do not use battery capacity alone to determine whether a battery fits your trimmer. Check the battery system and the approved battery information for your complete model.
What Battery Does the 24V-ST14 Use?
The current 24V-ST14 Cordless String Trimmer + Edger kit is offered with a 24V 4.0 Ah IONMAX lithium-ion battery and charger.
The approved operator's manual for the 24V-ST14 also identifies the model with a 24V 4.0 Ah battery.
The current product listing also provides a tool-only configuration. Battery and charger are sold separately when that configuration is selected.
What Battery Does the 24V-SB10 Use?
The current 24V IONMAX SharperBlade Cordless Trimmer + Edger kit is offered with a 2.0 Ah battery and charger.
A tool-only version is also available.
The 24V-SB10 tool-only operator's manual states that the battery and charger are not included and must be purchased separately.
What About the X20 Cordless Trimmer + Edger?
The current Sun Joe 20V ECOSHARP X20 Cordless Trimmer + Edger is listed with a 2.0 Ah battery and charger.
This model uses the 20V ECOSHARP X20 system. Follow the battery and charger information provided for the X20 trimmer rather than the 24V IONMAX guidance above.
Does My Trimmer Come with a Battery + Charger?
It depends on the product configuration you purchase.
| Product | Configuration | Battery + Charger |
|---|---|---|
| 24V-ST14 | 4.0 Ah Battery + Charger | Included |
| 24V-ST14-CT | Tool Only | Not included |
| 24V-SB10 | 2.0 Ah Battery + Charger | Included |
| 24V-SB10-CT | Tool Only | Not included |
| X20 Cordless Trimmer + Edger | 2.0 Ah Battery + Charger | Included |
Always check the selected product configuration before ordering. Some Shop Joe cordless trimmers are available both as a complete kit and as a tool-only version.
What Does "Tool Only" Mean?
Battery + Charger Included
If the product option states "Battery + Charger", the listed battery and compatible charger are included with that configuration.
Battery + Charger Sold Separately
If the product option states "Tool Only: No Battery + Charger", the battery and charger are not included.
Can a Different Ah Battery Change Runtime?
Yes. Battery capacity is measured in amp-hours (Ah), and using a different battery capacity can result in a different runtime.
Battery capacity affects runtime, but compatibility should still be confirmed using the battery system and the information for your exact trimmer model.
How Do I Find the Correct Battery?
- Check the complete model number on your trimmer.
- Determine whether the model uses 24V IONMAX or 20V ECOSHARP X20.
- Check your product page or operator's manual for the battery specified for that model.
- If purchasing a new trimmer, check whether you selected a battery + charger kit or a tool-only configuration.
