Charger Li-ion batteries 3.7V 10440-26650 with LED, from USB

With the new MC1 Plus, Xtar has introduced a very simple, yet highly functional LED display that provides information on the battery's charging progress and charging current.

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

What is the TC/CC/CV charging method? It is a three-stage charging process for lithium-ion cells that ensures that the cell is in good condition by charging at the right current at each stage and completing the charging process at the right time.
The different stages of the TC/CC/CV process are:
- TC phase: cells with a discharge voltage below 2.9 V are "woken up" with a lower current.
- CC phase: once 2,9 V has been reached, the cell is charged with a continuous current of 0,5 A (batteries up to 54 mm in length) or 1 A (batteries over 54 mm in length).
- CV phase: when the cell is nearly charged, the charger switches to charging at a decreasing current until the cell voltage reaches 4,2 V. When 4.2 V is reached, the charging process is complete - the battery is fully charged.

The charger considers batteries with a voltage of 4,0 V or more to be charged. To fully charge such a battery, place it in the charger before switching it on. Batteries left charged in the charger will discharge naturally. Charging will resume when the battery voltage drops below 4.1 V."

The Xtar ANT MC1 Plus charger has a function that reactivates deeply discharged cells and cells with a voltage of 0 V. Many chargers on the market cannot recharge such batteries. This is where the Xtar ANT-MC1 Plus charger comes to the rescue , allowing you to "rescue" such cells in most cases. Simply insert a deeply discharged battery into the ANT-MC1 Plus charger as you would for normal charging - the charger will detect the dead battery and try to reactivate it. Note! Elements that are discharged below a certain level are irreversibly damaged and may not be able to be reactivated. Avoid discharging lithium-ion batteries too deeply - this can significantly reduce their durability and capacity or render them completely ineffective.

Other manufacturers' chargers can significantly increase the temperature of the charged cells during charging. Excessive heating of the cells can lead to accelerated cell wear.
