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.
