In a small enclosure, a fully professional processor loader with a three-stage charging process TC/CC/CVis concealed. It charges 1-4 Li-ion 3.6/3.7 V cells with any capacity in sizes 14500, 14650, 16340, 17500, 17670, 18350, 18500, 18650, 18700. It is also possible to charge one or two batteries of size 20700, 21700, 22650, 25500 or 26650 (only in extreme channels).
What Is THE TC/CC/CV charging method? It is a three-step process of loading Li-ion cells to keep the cell in good condition by charging the right current at each stage and completing the charging process at the right moment.
The various stages of the TC/CC/CV process are:
• TC phase: Unloaded cells below 2.8 v are "woken up" by lower current.
• CC phase: When 2, 8V is reached, the cell is loaded with a constant current of 0, 5A or 1A (depending on the channel and power source used).
• CV phase: When the cell is already nearly charged, the charger switches to a decreasing current charge until it reaches a voltage of 4, 2V on the cell. After reaching 4, 2V the charging process is complete-the battery is fully charged.
Batteries with a voltage of 4, 1V or higher are treated by the charger as charged. To recharge such a full battery, please insert it into the charger before powering it in. When left in the charger, the charged batteries will be subjected to a natural self-discharge process. Charging will resume when the battery voltage drops below 4, 1V.
The Xtar MC4 Charger has a function of reactivating deeply discharged cells and cells with a Voltage Of 0v. Many chargers on the market are not able to charge such batteries. Here with the help comes the charger Xtar MC4, which in many cases allows you to "save" such cells. Just insert a deeply discharged battery into the MC4 charger, as with normal charging, the charger detects the unloaded link and attempts to reactivate it. Attention! Cells unloaded below a certain level are irreversible and reactivated may not be possible. Excessive discharge of Li-ion batteries should be avoided-this can lead to a significant reduction in their durability and capacity, or to their total malfunction.
Chargers from other manufacturers can significantly increase the temperature of the cells being charged during charging. Excessive heating of the cells can cause them to wear more quickly. When designing the MC4 loader, Xtar went one step further from the competition, solving this problem in a simple way: the power supply from the external power supply was applied. This ensures that the charging temperature in the MC4 battery rises by up to 15 degrees.
Supplied with the Xtar MC4 charger, we get the power ADAPTER and USB cable.
