CN3768-dat
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.
