HI,

I have an battery with led display of RSOC.However, after removing the charger, the led light takes 3 seconds to go off. How to set the led to go off in about 1 second?

Hello,

The amount of time the LED is held on is determined by the LED Hold Time seen below from the bq40z50 Technical Reference Manual.

If you are using bqStudio, this value can be altered by going to Data Memory -> LED Support -> LED Config.
