Charger XTAR SC1 for 18650/26650

XTAR SC1 charger for Li-ION rechargeable batteries with charging indicator

A fast charger for everyone!

SC1 is a charger for lithium-ion cells with micro USB charging input. The charger can charge one rechargeable lithium-ion cell of sizes: 18650/ 18700/ 20700/ 21700/ 22650/ 25500/ 26650 at a nominal voltage of 3.6V/3.7V. Thanks to the charging algorithm, the charger is an intelligent and safe device.

• Automatically selects the charging current up to 2A
• Protection against damage due to improper battery insertion
  
• Automatically terminates charging and resumes charging when voltage drops
• Soft start charging technology ensures longer cell life
• Charging anywhere and anytime using Micro-USB charging port
  
• 0V Reactivation function can save "dead" batteries
• Three-stage processor-controlled TC/CC/CV charging process
• Precise charge termination at 4.2V
• LED indicator of charging current and charge progress
• Protection against reverse polarity / short circuit / overcharging / overheating
• Warranty: 24 months

The TC/CC/CV charging algorithm used in the SC1 charger, is a charging process for Li-ION cells to ensure good cell condition. It involves charging with the right current and also completing the charge at the right time. TC/CC/CV charging stages, we can divide into:

• TC stage: the initial phase of checking and reactivating a cell whose voltage has dropped below 2.9V
  
• CC stage: then the cell is charged with a constant current of 50mA to 500mA (depending on the connected power source).
• CV stage: then the charger switches to charging with decreasing current until the cell voltage reaches 4.2V. When the cell voltage reaches 4.2V, charging is complete and the battery is fully charged
  

Included with the Xtar SC1 charger, you get a micro USB cable. For the set you need a power adapter, such as from a phone, or a computer with a free USB port, such as such. The minimum power of the charger should be 2100mA.

An interesting and safe solution in the SC1 charger is a separate 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 rise no more than 15 degrees on the cell. This directly affects the life of the battery.

On the other hand, the reactivation of "0V", 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.
