The XTAR VC2 Battery Charger is a dual-slot lithium-ion battery charger designed for compatible rechargeable batteries, including 18650 cells. Featuring an LCD display, independent charging slots and Micro-USB power input, the VC2 allows two compatible batteries to be charged simultaneously.

Each charging slot operates independently, with a maximum charging current of 0.5A per slot. The LCD screen displays charging information, including battery voltage, charging current and accumulated charged capacity.

Please note: The XTAR VC2 is designed for compatible 3.6V/3.7V rechargeable lithium-ion batteries. It is not suitable for ordinary disposable batteries or 1.2V NiMH cells. Batteries are sold separately.

Dual Independent Battery Charging Slots

The XTAR VC2 features two independent charging channels, allowing two compatible lithium-ion batteries to charge at the same time.

Each slot manages its own charging cycle, so compatible batteries with different remaining charge levels can be charged simultaneously. Both batteries do not need to finish charging at the same time.

The maximum charging current is 0.5A per slot, making the VC2 suitable for users who need a compact two-battery charging solution rather than a high-current charger.

LCD Display With Battery Charging Information

The XTAR VC2 includes an LCD screen that provides information about the charging process.

• Battery voltage: Displays the measured voltage of the inserted battery.
• Charging current: Shows the charging current during operation.
• Charged capacity: Displays the accumulated charge delivered during the current charging session, measured in mAh.
• Charging progress: Helps users monitor the charging cycle.

Important: The displayed mAh figure represents charge delivered during the current session. It is not a laboratory measurement of the battery's total capacity or remaining battery health.

Which Batteries Are Compatible With the XTAR VC2?

The XTAR VC2 is designed for selected cylindrical rechargeable 3.6V/3.7V lithium-ion batteries. Common supported sizes include:

• 10440
• 14500

Intelligent Three-Stage Charging

The XTAR VC2 uses a three-stage TC/CC/CV charging process for compatible lithium-ion cells.

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

Each charging channel automatically terminates its charging cycle when the charger's specified completion conditions are reached.

Built-In Charging Protection

The XTAR VC2 incorporates electronic charging controls, including reverse-polarity protection, short-circuit protection and automatic charge termination.

The charger also includes a low-voltage battery activation function for certain compatible cells. This feature does not make damaged, swollen, leaking or otherwise unsafe batteries suitable for reuse.

How to Use the XTAR VC2 Charger

1. Inspect the charger and batteries for visible damage before use.
2. Connect the charger to a suitable USB power supply using the correct Micro-USB cable.
3. Insert one or two compatible rechargeable lithium-ion batteries, observing the polarity markings.
4. Check the LCD screen to confirm that charging has started.
5. Monitor the charging information displayed for each battery.
6. Allow the charging cycles to finish according to the manufacturer's instructions.
7. Disconnect the power supply and remove the charged batteries.

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

XTAR VC2 vs XTAR MC1 Charger

The XTAR VC2 and XTAR MC1 are both designed for compatible rechargeable lithium-ion batteries, but they offer different charging arrangements.

• XTAR VC2: Two independent charging slots and an LCD information display.
• XTAR MC1: One charging slot in a smaller, simpler design.

If you need to charge two compatible removable batteries, the VC2 offers an additional charging slot and more detailed charging information.
