Common Reasons for Theragun Battery Not Charging

Experiencing a Theragun battery that refuses to charge can be frustrating, especially when you’re in need of its rejuvenating benefits. There are several common reasons why your Theragun battery may not be charging as expected. Let’s explore some of these potential causes:

A. Faulty power source or charging cable:

One possible reason for the battery not charging is a faulty power source or charging cable. It’s essential to verify that the power outlet you’re using is functioning correctly. Try plugging another device into the same outlet to ensure it’s providing power. Additionally, inspect the charging cable for any visible damage, such as frayed wires or loose connections.

B. Theragun battery depletion or aging:

Over time, batteries naturally lose their capacity to hold a charge. If your Theragun battery has been extensively used or if it has been a while since the last charge, it’s possible that the battery has depleted to a level where it no longer charges. In such cases, the battery may need to be replaced to restore proper functionality.

C. Software or firmware issues:

Occasionally, software or firmware issues can interfere with the charging process. Glitches or bugs in the device’s operating system may cause the battery not to charge properly. In these situations, performing software or firmware updates may resolve the issue. Manufacturers often release updates to address known bugs and enhance device performance.

D. Physical damage to the battery or charging port:

Physical damage to the battery or charging port can prevent the Theragun from charging correctly. If the battery or charging port has been subjected to impact or excessive force, it may result in a malfunction. Inspect the battery for any signs of damage, such as swelling or leakage. Similarly, check the charging port for debris or obstructions that may hinder proper charging.

Identifying the root cause of the battery not charging is crucial in troubleshooting the issue effectively. In the following sections, we will delve into practical steps you can take to address each of these potential causes and get your Theragun battery charging again.

Theragun Battery Not Charging Troubleshooting Steps

When faced with a Theragun battery not charging, there are several troubleshooting steps you can take to identify and resolve the issue. Follow these steps to get your Theragun back to its optimal charging performance:

A. Check the power source and charging cable:

  1. Verify the power outlet is functional: Plug another device into the same outlet to ensure it’s supplying power. If the outlet is not working, try using a different outlet or consider resetting the circuit breaker.
  2. Inspect the charging cable for any visible damage: Examine the charging cable for frayed wires, bent connectors, or other signs of damage. If you notice any issues, try using a different charging cable or power adapter.
  3. Try using a different charging cable or power adapter: Borrow a compatible charging cable or power adapter from a friend or family member and attempt to charge your Theragun with it. If the battery starts charging, it indicates that the original charging cable or power adapter might be faulty and needs to be replaced.

B. Restart and Reset the Theragun:

  1. Power off the device and unplug it from the charger: Turn off your Theragun and disconnect it from any power source.
  2. Wait for a few seconds and then plug it back in: Allow a brief interval before plugging the Theragun back into the charger. This pause can help reset the charging mechanism.
  3. Restart the Theragun and check if the battery starts charging: Power on your Theragun and observe if the battery begins to charge. Sometimes, a simple restart can resolve minor software or connectivity issues.
  4. If the issue persists, perform a factory reset (refer to the manufacturer’s instructions): Performing a factory reset will restore the Theragun to its original settings, eliminating any software glitches that may be hindering the charging process. However, note that a factory reset erases all personalized settings, so proceed with caution and back up any important data if possible.

C. Software and Firmware Updates:

  1. Check for any available software or firmware updates: Visit the manufacturer’s website or use the Theragun mobile app to check for updates specific to your device model.
  2. Download and install the latest updates following the manufacturer’s instructions: If updates are available, download and install them according to the provided guidelines. These updates often include bug fixes and optimizations that can resolve charging-related issues.
  3. Retry charging the battery after the updates are installed: Once the updates are installed, connect your Theragun to the charger and check if the battery begins to charge properly. Software or firmware updates can often address underlying issues that affect charging performance.

D. Battery and Charging Port Inspection:

  1. Examine the battery for any signs of physical damage: Carefully inspect the battery for bulging, leakage, or other visible damage. If you notice any abnormalities, it may indicate a damaged battery that needs to be replaced. Contact the manufacturer’s customer support for guidance on obtaining a replacement battery.
  2. Ensure the charging port is clean and free from debris: Use a soft cloth or compressed air to clean the charging port on your Theragun. Remove any dust, dirt, or lint that might be obstructing the connection between the charging cable and the device. Be gentle to avoid causing further damage.
  3. If necessary, contact the manufacturer’s customer support for assistance: If all the previous steps fail to resolve the battery charging issue, reach out to the manufacturer’s customer support. They will provide further guidance and potential solutions based on your specific situation.

By systematically going through these troubleshooting steps, you can often identify and resolve the issue preventing your Theragun battery from charging. Remember to follow the manufacturer’s instructions and exercise caution when performing any troubleshooting steps.
