Thanks for your support.


Here are the steps about how to fully charge the item:


  1. Use the battery to 2% before you perform the next charge.
  2. please turn off the fast charging option.
  3. Charge it around 7 hours. Don't stop charging even it reaches 100% within 4 hours. Because the power percentage is programmed to the original battery. So actually it doesn't get fully charged even if it shows 100%.
  4. Fully charge performed until it shows the words like " FULLY CHARGED".
