fast charger for cylindrical batteries Li-ion 18650 Xtar MC1 Plus

Professional Compact Processor Charger
Xtar MC1 Plus
for Li-ion batteries in sizes 18650 and other

Hidden in a small case is a fully professional processor charger with a three-stage TC/CC/CV charging process. Charges 3.6/3.7V Li-ion cells of any capacity in sizes 10440, 14500, 14650, 16340, 17500, 17670, 18350, 18500, 18650, 18700 , 20700, 21700 - unprotected only, 22650, 25500, 26650.

What is the TC/CC/CV charging method? It is a three-stage process of charging Li-ion cells to ensure that the cell is kept in good condition by charging with the right current at each stage and completing the charging process at the right time.
The individual steps of the TC/CC/CV process are:
•TC phase: Cells discharged below 2.9V are 'woken up' with a lower current.
• CC phase: when 2.9V is reached, the cell is charged with a constant current of 0.5A (batteries up to 54mm in length) or 1A (batteries over 54mm in length).
•CV phase: when the cell is almost charged, the charger switches to decreasing current charging until the voltage of 4.2V is reached on the cell. When 4.2V is reached, 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 fully charge such a battery, insert it into the charger before plugging it in. Charged batteries left in the charger will undergo a natural process of self-discharge. Charging will resume when the voltage on the battery drops below 4.1V.

The Xtar MC1 Plus charger has the 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. This is where the Xtar MC1 charger comes to the rescue, which in many cases allows you to 'save' such cells. Simply insert the deeply discharged battery into the MC1 charger as you would with normal charging - the charger will detect the discharged cell and attempt to reactivate it. Remark! Cells discharged below a certain level are irreparably damaged and may not be able to reactivate them. Avoid discharging Li-ion batteries too deeply – this can lead to a significant reduction in their lifespan and capacity, or lead to their complete inoperability.

Chargers from other manufacturers can significantly increase the temperature of the charged cells during charging. Too much heating of the cells can cause them to wear out faster. When designing the MC1 Plus, Xtar went a step further than the competition by solving this problem in a simple way: power from an external power supply was used. Thanks to this, the temperature of the battery charged in the MC1 Plus will increase by a maximum of 15 degrees.

The Xtar MC1 Plus charger comes with a micro USB cable and a cover to protect the charger during transport. A power supply is not included. To power the charger, you will need any charger with a micro USB cable, e.g. from a phone, or a USB socket, or a computer with a free USB port. The recommended minimum power of the charger is 1A (1000mA). It is possible to use a charger with less power, but in this case the charging time will be extended.
