Battery Level Drains from 98% to 10 Rapidly, Stacker Stops

• Battery Failure (Caused by Long-Term Inactivity or Deep Discharge)

  Troubleshooting:

  Use a multimeter to measure battery voltage.

  
  

  If the voltage of a single battery is lower than 7V, it is a serious discharge;

  If the voltage difference between two batteries is greater than 0.7V, it indicates a battery failure.

  Solution: Re-activate the battery or replace two new batteries.
