The CN3768 charging system incorporates several automatic features to optimize battery health and longevity.

Deeply discharged batteries are initially trickle charged at 17.5% of the programmed constant charge current. This continues until the cell voltage reaches 75% of the regulation voltage in over-charge mode.

The over-charge phase ends when the charging current decreases to 38% of the constant charge current, at which point the system transitions to float charge mode.

If the battery voltage subsequently drops below 83.95% of the over-charge voltage while in float-charge mode, a new charge cycle automatically begins.

Furthermore, the CN3768 automatically enters sleep mode when the input voltage falls below the battery voltage, conserving power.
