Charging Principle
  • When the battery voltage is below 13 volts, boosting charging occurs.
  • Charging stops if the instantaneous voltage exceeds 14.7 volts.
  • When the average battery voltage falls within the range of 13.5 to 14.2 volts, trickle charging is activated.
  • An intelligent chip employs an algorithm to maintain the battery voltage within the range of 13.7 to 14.1 volts using a small current. The specific voltage values may vary for different batteries.
