What to look for
Frequently asked questions
Can I use a battery string trimmer in the rain?
Yes, if it has a good IP rating like IPX4, it can handle light rain and wet grass. However, it is best to avoid heavy downpours and never submerge it in water.
What does IPX4 mean?
IPX4 means the tool is protected against water splashes from any direction. It is not waterproof, but it can withstand rain and wet conditions.
Are brushless motors worth the extra cost?
Yes, brushless motors are more efficient, have longer life, and provide better performance. They are especially beneficial in weatherproof tools because they are sealed and less prone to damage.
Do all battery trimmers come with a battery and charger?
No, some are sold as ‘tool only’ to save money if you already own the battery system. Check the product details to see what is included.
How long does a battery last on a string trimmer?
Runtime varies by battery capacity and cutting conditions. On average, you can expect 20 to 40 minutes of continuous use on a full charge.
Can I use a regular battery string trimmer on wet grass?
It is risky because moisture can damage the motor and electronics. A weatherproof model is designed to handle moisture safely.
What is the best way to store a battery string trimmer?
Store it in a dry place, ideally indoors. Remove the battery and keep it charged between 30% and 70% if storing for a long time.
Are battery trimmers as powerful as gas trimmers?
Modern battery trimmers, especially those with brushless motors and higher voltage, can match the power of many gas models for residential use. They are also quieter and require less maintenance.
How do I know if a trimmer is weatherproof?
Look for an IP rating on the packaging or specifications. IPX4 or higher indicates protection against splashing water.
What should I look for in a trimmer for thick weeds?
Choose a model with a brushless motor, higher voltage (40V or more), and a cutting width of at least 15 inches. Some have a high-torque mode for tough jobs.
Final word
For most homeowners, the DEWALT 20V MAX XR String Trimmer is the best overall choice due to its power, durability, and weather resistance. If you need a longer runtime and are willing to invest, the EGO Power+ is excellent. For budget shoppers, the BLACK+DECKER 20V MAX offers solid performance at a lower price. Choose the DEWALT if you want a reliable tool that will last for years.
