Intelligent Three-Stage Battery Charging

The XTAR MC1 uses a TC/CC/CV charging process to manage the charging cycle of compatible lithium-ion batteries.

• TC (Trickle Charge): Applies a reduced charging current when appropriate for a low-voltage battery.
• CC (Constant Current): Supplies a controlled charging current during the main charging stage.
• CV (Constant Voltage): Maintains the required voltage while the charging current reduces towards the end of the cycle.

The charger automatically terminates charging when its completion conditions are reached.

Built-In Charging Protection

The XTAR MC1 includes several electronic charging controls:

• Reverse-polarity protection: Helps protect against incorrectly inserted batteries.
• Short-circuit protection: Helps protect the charging circuit.
• Charge termination: Stops the charging process when the battery reaches the charger's completion threshold.
• Temperature monitoring: Supports charging-current management when operating temperatures increase.

The charger also includes a battery activation function that may attempt to recover certain deeply discharged compatible cells. This function cannot restore every battery, and damaged or excessively discharged cells must not be reused.

How to Use the XTAR MC1 Charger

1. Inspect the charger and battery for visible damage before use.
2. Connect the MC1 to a suitable USB power source using the correct Micro-USB cable.
3. Insert one compatible rechargeable lithium-ion battery, observing the polarity markings.
4. Check the charger's indicator to confirm charging has started.
5. Allow the charging cycle to complete, following the indicator information in the manufacturer's instructions.
6. Disconnect the power supply and remove the charged battery.

Use the charger on a suitable non-flammable surface, away from excessive heat and moisture. Do not leave batteries charging unattended.

Single-Slot Charging for Removable Vape Batteries

The XTAR MC1 is a practical option for users who need to charge one compatible removable battery at a time. Its 0.5A charging current is suited to controlled charging rather than high-speed charging.

If you regularly charge several removable batteries, a multi-slot charger may be more convenient. Browse our Battery Chargers Collection or view the XTAR MC4S Charger for a four-slot alternative.

What's Included?
