Battery Not Charging

Solo analyzer battery won't charge or shows weak battery repeatedly.

Applies to: Solo Analyzers

Problem description: The Solo Analyzer battery will not charge, charges very slowly, or repeatedly shows a low battery warning. To fix this, work through the steps below — most charging issues are resolved by trying a different cable or updating the firmware.

Possible causes:

  • Battery age/degradation
  • Charging circuit failure
  • Cable/connector issues
  • Battery protection triggered
  • Firmware charging bug

Step-by-step troubleshooting:

  1. Try a different USB cable and charger.
  2. Check the charging indication: while the device is powered on, press and hold the Down Arrow button to display the battery status screen.
  3. Update the device firmware to the latest version via the Divesoft Desktop application.
  4. Clean the charging contacts with a dry cloth or cotton swab.
  5. If you have a multimeter, measure the battery voltage directly. A healthy Li-ion cell should read between 3.6 V and 4.2 V.
  6. If possible, monitor the charging current to confirm the charger is delivering power.

When to contact service: If the battery still will not charge after completing the steps above, contact Divesoft Support. A service technician will inspect the charging circuit and replace the battery if necessary.
