Charger XTAR MC1 for 18650/26650

Professional processor charger

XTAR MC1 for rechargeable Li-ION cells

XTAR MC 1 is a charger for lithium-ion cells with USB-C charging input. The charger can charge one rechargeable battery pack of sizes: 10440/ 14500/ 14650/ 16340/ 17335/ 17500/ 17670/ 18350/ 18490/ 18500/ 18650/ 18700/ 20700/ 21700/ 22650/ 25500/ 26650 at 3.6V/3.7V nominal voltage. With TC/CC/CV charging algorithm and real-time detection, the charger is an intelligent and safe device.

Features:

• Protection against damage due to improper battery insertion and against short circuit.
• In case of high temperature operation, the charger will automatically reduce the charging current to a lower one.
• Automatically terminate charging and resume charging when the voltage drops.
• Three-stage processor-controlled TC/CC/CV charging process.
• Soft start charging technology ensures longer cell life.
• 0V Activation Function can save your "dead" batteries.
• Charging 20700 and 21700 batteries, unprotected only
• Charging 26650 batteries with "flat plus" only
• Warranty: 24 months

The XTAR MC1 charger comes with a USB-C cable and a carrying case to protect the charger for transport. For the set you need a power adapter, such as from a phone, or a computer with a free USB port. The minimum power of the charger should be 500mA.

An interesting and safe solution in the MC1 charger is a separately connected power supply. This prevents unnecessary heating of the charged cell. When the set is working, the power supply itself heats up and not the charged cell. As a result, the temperature during charging, can increase on the cell no more than 15°C. This directly affects the life of the battery.

In the MC1 charger, we can also recharge the batteries, up to full. First, we put 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 as charged by the charger. Charging will start when the voltage drops below 4.1V.

On the other hand, reactivating discharged cells involves inserting the cell into the charger and checking the voltage. With this function, we can check each cell in the appropriate size. When a discharged cell is detected, the charger will attempt to reactivate it. Note that exceeding the minimum voltage on the cell will limit the possibility of reactivating and saving such a battery.
