The most important features:
- processor-controlled three-stage charging process TC/CC/CV,
- powered by any micro USB charger or from a computer USB port (min. 0.5A),
- small dimensions - easy to carry,
- reactivation function of deeply discharged cells,
- protections: short-circuit, thermal, reverse polarity protection.
A fully professional processor charger with a three-stage TC/CC/CV charging process is hidden in a small housing. 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 - only unprotected.
What is the TC/CC/CV charging method? It is a three-stage Li-ion cell charging process that ensures the cell is maintained in good condition by charging with the right current at each stage and ending the charging process at the right time.
The individual stages of the TC/CC/CV process are:
- TC phase: cells discharged below 2.9V are 'wake up' with a lower current.
- CC phase: after reaching 2.9V, the cell is charged with a constant current of 0.5A.
- CV phase: when the cell is almost fully charged, the charger switches to charging with decreasing current until reaching 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 fully charge such a battery, insert it into the charger before connecting it to the power supply. Charged batteries left in the charger will undergo a natural self-discharge process. Charging will resume when the battery voltage drops below 4.1V.
The Xtar MC1 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 in handy, which in many cases allows you to 'rescue' such cells. It is enough to insert a deeply discharged battery into the MC1 charger, as with normal charging - the charger will detect a discharged cell and attempt to reactivate it. Attention! Cells discharged below a certain level are irreparably damaged and may not be reactivated. Too deep discharge of Li-ion batteries should be avoided - this may lead to a significant decrease in their durability and capacity or lead to their complete inoperability.
Chargers from other manufacturers can significantly increase the temperature of the charged cells during charging. Excessive heating of the cells can cause their faster wear. When designing the MC1 charger, Xtar went a step further than the competition, solving this problem in a simple way: it was powered from an external power supply. Thanks to this, the temperature of the battery charged in the MC1 will increase by no more than 15 degrees.
The Xtar MC1 charger comes complete with a micro USB cable and a cover protecting the charger during transport. The power supply is not included in the set. To power the charger, any charger with a micro USB cable, e.g. from a phone, or a USB socket or a computer with a free USB port is enough. The recommended minimum charger power is 0.5A (500mA).
