Professional processor-controlled charger

XTAR MC1 for Li-ion rechargeable batteries

The XTAR MC1 is a charger for lithium-ion cells with a USB-C charging input. The charger can charge one battery in the following sizes at a nominal voltage of 3.6V/3.7V: 10440/ 14500/ 14650/ 16340/ 17335/ 17500/ 17670/ 18350/ 18490/ 18500/ 18650/ 18700/ 20700/ 21700/ 22650/ 25500/ 26650. Thanks to the TC/CC/CV charging algorithm and real-time detection, the charger is an intelligent and safe device.

Features:

Protection against damage caused by inserting the battery incorrectly and against short circuits.
When operating at high temperatures, the charger automatically reduces the charging current.
Automatic termination of charging and resumption of charging when the voltage drops.
Three-stage processor-controlled TC/CC/CV charging process.
The soft-start charging technology ensures a longer cell life.
The 0V Activation Function can revive your “dead” batteries.
Charging of 20700 and 21700 batteries, unprotected only
Charging of 26650 batteries only with a “flat top”
Warranty: 24 months


With the MC1 charger, batteries can be topped up to full charge. First insert the battery into the charger and wait until its voltage drops below 4.1V. This will occur during the self-discharge process. Batteries with a voltage of 4.1V or higher are treated by the charger as charged. Top-up charging will begin when the voltage drops below 4.1V.

Reactivating discharged cells involves inserting the cell into the charger and checking its voltage. This function allows you to check any cell of the appropriate size. After detecting a discharged cell, the charger will attempt to reactivate it. Please note that falling below the minimum voltage of the cell limits the possibility of reactivating and saving such a battery.
