XTAR VC8 Battery Charger User Manual

1. Introduktion

The XTAR VC8 is an advanced 8-slot battery charger designed for a wide range of rechargeable batteries, including 3.6V/3.7V Li-ion (such as 18650, 21700, 26650) and 1.2V Ni-MH (AA, AAA, C) types. It features an intuitive LCD display, multiple charging currents, and specialized functions like grading mode to test real capacity and storage mode to maximize battery lifespan. This manual provides essential information for safe and efficient operation of your VC8 charger.

2. Produktfunktioner

• 8-Slot Versatility: Charges up to 8 batteries simultaneously, supporting various sizes including protected 21700, 18650, 20700, 10440, 18700, 26650 Li-ion, and Ni-MH AA, AAA, C batteries.
• QC3.0 Fast Charging: Includes a QC3.0 wall charger, enabling a maximum 3A current for a single slot (CH1/CH8) when battery resistance is low.
• Selectable Charging Currents: Offers 5 optional currents (3A, 2A, 1A, 0.5A, 0.25A) for user selection, allowing optimized charging based on battery type and capacity.
• Grading Mode (CH1-CH4): Tests the real capacity of batteries through a "charging-discharging-charging" cycle, helping identify overstated or underperforming batteries.
• Storage Mode (CH1-CH4): Charges or discharges batteries to their rated voltage (3.7V for Li-ion) for optimal long-term storage, maximizing battery lifespan and ensuring safety.
• High-Definition VA LCD Screen: Provides clear, real-time information on charging status, voltage, current, capacity, and internal resistance.
• Type-C-drevet: Utilizes a common Type-C port for power input, compatible with most modern phone adapters.
• Avancerede sikkerhedsfunktioner: Built-in high-precision MCU and real-time temperature control protection system prevent over-current, over-charge, over-voltage, and short-circuiting. Automatically stops charging when batteries are full.
• Holdbar konstruktion: Made from flame-retardant and fire-resistant ABS materials for enhanced safety and longevity.

Figure 5.2: The XTAR VC8 charger can accommodate and charge up to eight 21700 batteries at once.

5.2 Forståelse af LCD-skærmen

The high-definition VA LCD screen provides real-time data for each slot:

• Voltage (V): Nuværende voltage af batteriet.
• Nuværende (A): Opladnings- eller afladningsstrøm.
• Kapacitet (mAh/Wh): Accumulated capacity during charging or discharged capacity during grading.
• Internal Resistance (mΩ): Displays the internal resistance of the battery.
• Batteritype: Indicates whether the detected battery is Li-ion or Ni-MH.
• Opladningsstatus: Progress bar and "Full" indicator when charging is complete.

5.3 Selecting Charging Current

The VC8 charger offers five selectable charging currents: 3A, 2A, 1A, 0.5A, and 0.25A. To change the current for a specific slot:

1. Press the "Mode" button to select the desired channel group (CH1-CH4 or CH5-CH8).
2. Press the "Curr." button repeatedly to cycle through the available current options for the selected channels.
3. The charger will automatically apply the selected current. Note that 3A is only available for CH1 and CH8 under optimal conditions.

5.4 Grading Mode (Capacity Test)

The grading mode is available for slots CH1-CH4. This function tests the true capacity of your batteries:

1. Insert batteries into CH1-CH4.
2. Press and hold the "Mode" button until "Grade" appears on the display for the selected channels.
3. The charger will first fully charge the battery, then discharge it to measure its capacity, and finally recharge it. The measured capacity will be displayed.

This process helps identify batteries with degraded performance or overstated capacities.

5.5 Opbevaringstilstand

The storage mode is also available for slots CH1-CH4. This mode prepares batteries for long-term storage by adjusting their voltage to an optimal level (typically 3.7V for Li-ion):

1. Insert batteries into CH1-CH4.
2. Press and hold the "Mode" button until "Store" appears on the display for the selected channels.
3. The charger will either charge or discharge the battery until it reaches the optimal storage voltage.

Using storage mode helps prolong the overall lifespan of your batteries.
