-
Professional Battery Diagnostics:
-
Capacity Grading (CH1~CH4): Runs a full charge-discharge-charge cycle to accurately measure true battery capacity, identifying weak or counterfeit cells.
-
Internal Resistance (IR) Test: Accurately measures the internal resistance of the battery, helping users filter out aged or deteriorated batteries.
-
Intelligent Storage Mode: Automatically charges or discharges batteries to their optimal long-term storage voltage (3.7V for Li-ion, 1.2V for Ni-MH), significantly reducing capacity loss and extending battery lifespan.
-
0V Activation & Smart Algorithms: Safely revives over-discharged batteries. Employs a TC-CC-CV (Trickle-CC-CV) charging algorithm for Li-ion batteries and precise 0ΔV / -ΔV detection for Ni-MH batteries to ensure a full and healthy charge.
-
Extensive Battery Compatibility: Supports 3.6V/3.7V Li-ion batteries (10440, 14500, 14650, 16340, 17500, 17670, 18350, 18490, 18500, 18650, 18700, 20700, 21700, 22650, 25500, 26650) and 1.2V Ni-MH/Ni-CD batteries (AAAA, AAA, AA, A, SC, C, D). Notably supports protected 20700 and 21700 batteries.
-
Adjustable Charging Currents: Offers four manual current gears: 250mA (8 slots), 500mA (8 slots), 1000mA (4 slots), and 2000mA (Slots CH1/CH8), allowing users to choose the optimal speed for different battery capacities.
-
Advanced Safety & Temperature Control: Built-in over-voltage, over-current, short-circuit, reverse polarity, and over-charge protection. Features an intelligent cooling system to ensure stable operation even during high-current continuous charging.

Frequently Asked Questions (FAQ)
Q1: What is included in the package?
A1: The package includes 1x XTAR VC8 8-slot Smart Charger, 1x USB-A to USB-C Charging Cable, and 1x User Manual. (Batteries are not included).
Q2: What is the maximum charging current of the VC8 charger?
A2: The VC8 offers multiple adjustable current settings. The maximum single-slot charging current is 3A (only available when charging a single battery in Slot CH1 or CH8). It also supports 2A dual-slot, 1A four-slot, and 0.5A / 0.25A eight-slot configurations.
Q3: How does the "Capacity Grading" mode work?
A3: Capacity Grading mode is specifically supported in slots CH1 to CH4. It runs a full cycle (charge -> discharge -> recharge) to accurately measure the true mAh capacity of the battery. This helps you easily identify old, degraded, or counterfeit batteries.
Q4: What does the "Storage Mode" do?
A4: If you do not use batteries for a long time, Storage Mode automatically charges or discharges them to the optimal long-term storage voltage (3.7V for 3.6V/3.7V Li-ion, 1.2V for Ni-MH). This prevents capacity loss over time and significantly extends battery lifespan.
Q5: Can I charge Li-ion and Ni-MH batteries at the same time in the VC8?
A5: Yes. The XTAR VC8 features 8 completely independent charging circuits. You can safely mix 3.6V/3.7V Li-ion batteries and 1.2V Ni-MH/Ni-CD batteries in any slot simultaneously without compromising performance or safety.
