Battery performance troubleshooting

Is a suitable battery being Used? 

  • This tool performs best with a 4Ah battery or higher for optimal runtime. 
  • The higher the Ah (amp-hour) rating, the longer the runtime. 
  • If using a battery lower than 4Ah, consider upgrading to a higher-capacity battery for better performance. 


Does the task require a capacity larger Battery? 

  • If the battery does not last long enough to complete your task, a larger capacity battery may be needed. 
  • Larger batteries provide longer runtime, especially for demanding applications. 


Check if the issue is with the battery or the tool 

  • Try inserting a fully charged battery into the tool to see if it starts. 
  • If the tool works with a different battery, the issue may lie with the original battery. 
     

Is the battery older than 3 years? 

  • Over time, rechargeable batteries degrade, leading to reduced performance. 
  • To check the age:
    1. Locate the serial plate on the bottom of the battery.
    2. If the manufacture year is over 3 years ago, the battery may need replacing. 


Are you storing the tool and battery in a cold area? 

  • Cold temperatures can reduce battery performance and runtime. 
  • Keep the battery and tool warm (not hot) when not in use. 
  • Consider using an insulated battery jacket if available. 


Are you running the tool continuously at full power? 

  • Running the tool at full power unnecessarily can drain the battery faster. 
  • Use the appropriate power setting for your task. 
  • Lower the speed or power when possible to conserve battery life. 


Is there a build-up of dust and debris? 

  • Accumulated dust and debris inside the Trim Route can affect performance and increase heat and noise. 
  • Regularly clean the Trim Router’s base and housing to maintain optimal operation.
