The topping charge typically takes twice as long as the initial charge.
Depending on the charger and the self discharge of the ASUS C23-UX21, ZENBOOK UX21 UX21E 35Wh Battery, a topping charge may be implemented once every 500 hours or 20 days. Typically, the charge kicks in when the open terminal voltage drops to 4.05 volts per cell and turns off when it reaches 4.20V/cell.
