Xtar is a renowned manufacturer of high-quality chargers for Li-ion batteries, flashlights, and Li-ion batteries. Xtar products are sold in over 120 countries, including the USA, Germany, Japan, and Russia. For the production of Xtar chargers, the highest quality materials are used - from the casing material to efficient electronics. All Xtar chargers have CE certification required in European markets.
Hidden in a compact casing is a fully professional microprocessor charger with a three-stage charging process for Li-ion cells using the TC/CC/CV method and the method 0△V and -△V for NiMH batteries. It charges 1-4 Li-ion cells 3.6 / 3.7V and 1.2V NiMH of any capacity in sizes 10440, 14500, 14650, 16340, 17500, 17670, 18350, 18500, 18650, 18700, AAAA, AAA, AA, A. It is also possible to charge one or two batteries of size 20700, 21700 - only unprotected, 22650, 25500 / 26650 / SC / C (only in extreme channels).
What is the TC/CC/CV charging method? It is a three-stage charging process for Li-ion cells that ensures the cell is maintained in good condition by charging with the appropriate current at each stage and completing the charging process at the right moment.
The individual stages of the TC/CC/CV process are:
- TC Phase: cells discharged below 2.8V are "woken up" with a lower current.
- CC Phase: after reaching 2.8V, the cell is charged with a constant current of 0.5A or 1A (depending on the channel and the power of the used power source).
- CV Phase: when the cell is almost fully charged, the charger switches to charging with a decreasing current until the voltage of 4.2V is reached on the cell. After reaching 4.2V, the charging process is complete - the battery is fully charged.


Chargers from other manufacturers can significantly raise the temperature of the charged cells during charging. Excessive heating of the cells can cause them to wear out faster. In designing the MC4S charger, Xtar has taken a step further than the competition by solving this problem in a simple way: external power supply was used. As a result, the temperature of the battery being charged in the MC4S will rise by a maximum of 15 degrees.
USB cable included with the Xtar MC4S charger.
Batteries with a voltage of 4.1V or higher are treated by the charger as charged. To recharge such a battery to full, it should be placed in the charger before plugging it into the power supply. Charged batteries left in the charger will undergo a natural self-discharge process. Charging will resume when the voltage on the battery drops below 4.1V. The Xtar MC4S charger has a reactivation function for deeply discharged cells and cells with a voltage of 0V. Many chargers on the market are unable to charge such batteries. Here, the Xtar MC4S charger comes to the rescue, which in many cases allows for the "rescue" of such cells. Just place the deeply discharged battery in the MC4S charger, just like with normal charging - the charger will detect the discharged cell and attempt to reactivate it.
Note! Cells discharged below a certain level may suffer irreversible damage and their reactivation may be impossible. It is important to avoid overly deep discharging of Li-ion batteries - this can lead to a significant reduction in their lifespan and capacity or render them completely inoperable.
