The standard Li-Ion chemistry is charged to 4.2 V, and then the charge terminated after the charge current drops below a threshold. If you continue holding the cell voltage at 4.2 V for a long time, even though the current has dropped to a very low value, you will damage the battery, plating out lithium in an unusable form.. This charging protocol is a

The temperatures have dropped to -5 to - 9 Celsius this week. Will that effect the ability for the cells to reach a full charge. The reason I ask is I have been charging one cell with a variable power supply that I think has a lower state of charge than others.
The charging voltage of a single cell will not exceed the voltage regulation value, while other single cells continue to charge through the voltage regulator tube bypass charge. Because the power of each cell is almost full at this time, it is only balancing each cell, so the charging current is small, and each battery cell is fully charged

The customer's design specification called out 12.60V for the voltage set point (with an overall accuracy better than 1%). The maximum charging current is 3A (and must be limited by the DC input source).
To maximize power, the charger must never be in supplement mode operation where the battery discharges current into the system. Other internal clamps must be neglected through either the charge current setting or the input current limit (I INDPM) setting, which avoids limiting charge current or input power respectively.
A 1C rate means that the discharge current will discharge the entire battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. A 5C rate for this battery would be 500 Amps, and a C/2 rate would be 50 Amps. Similarly, an E-rate describes the discharge power.
During the current limit phase, the charger must limit the current to the maximum allowed by the manufacturer (shown as 1c here) to prevent damaging the batteries. About 65% of the total charge is delivered to the battery during the current limit phase of charging.
During the 1c current limit charge phase, the battery reaches 4.2V with only about 65% of charge capacity delivered, due to the voltage drop across the ESR. The charger must then reduce the charging current to prevent exceeding the 4.2V limit, which results in the decreasing current as shown in Figure 5. FIGURE 6. BATTERY EQUIVALENT CIRCUIT
