Key Features
-
Complete Professional Power Kit: Includes one XTAR VC8 8-slot smart charger (with USB cable) and one or two XTAR 18650 3500mAh 10A protected button-top batteries based on your selection.
-
High-Capacity Battery Specifications: Features 3500mAh true capacity, a 3.6V nominal voltage, a 4.2V charging cut-off, and a 10A max continuous discharge. Built-in protection PCB prevents overcharge and short circuits. Ultra-low internal resistance (≤45 mΩ) and supports over 800 charge cycles for long-lasting performance.
-
8 Fully Independent Charging Slots: Each slot features independent circuit control, allowing you to charge any combination of batteries without mutual interference. Supports both Li-ion and Ni-MH/Ni-CD batteries simultaneously.
-
3A Ultra-Fast Charging: Equipped with a QC3.0 Type-C input (5V/9V), providing a maximum 3A charging current when a single battery is placed in slot CH1 or CH8, drastically reducing downtime.
-
Dual VA LCD Screens & Advanced Diagnostics: High-contrast dual screens display real-time voltage, current, capacity (mAh), and internal resistance (mΩ). The Capacity Grading mode (supported in CH1-CH4) runs a full cycle to reveal true battery health, while the IR test effectively filters out aged or degraded cells.
-
Intelligent Storage Mode & 0V Activation: Automatically charges or discharges batteries to the optimal long-term storage voltage of 3.7V for Li-ion batteries to prevent capacity loss. The 0V activation feature safely revives over-discharged batteries.

Frequently Asked Questions (FAQ)
Q1: What is included in this bundle?
A1: The bundle includes one XTAR VC8 8-slot smart charger, one USB-A to USB-C charging cable, one user manual, and either 1 or 2 units of the XTAR 18650 3500mAh 10A protected button-top batteries based on your selected variant.
Q2: How do I achieve the maximum 3A fast charging speed with the VC8?
A2: To achieve the maximum 3A fast charging speed, you must use a QC3.0 (9V/2A) power adapter and charge a single battery exclusively in slot CH1 or CH8. The charger will automatically detect the input and output 3A.
Q3: How does the "Capacity Grading" mode work for this 18650 battery?
A3: Capacity Grading mode (supported in CH1 to CH4) runs a complete charge-discharge-charge cycle on the battery. This accurately measures the true mAh capacity of the 3500mAh cell, allowing you to easily identify if it has aged or if it's a counterfeit cell.
Q4: What is the purpose of the "Storage Mode"?
A4: If you do not plan to use this 3.6V 18650 battery for an extended period, the Storage Mode will automatically charge or discharge it to the optimal long-term storage voltage of 3.7V. This significantly slows down capacity degradation and maximizes the battery's overall lifespan.
Q5: Can I charge Ni-MH batteries alongside this Li-ion battery in the VC8?
A5: Yes. The XTAR VC8 features 8 completely independent charging circuits. You can safely place a 3.6V Li-ion battery in one slot and a 1.2V Ni-MH battery in any other slot simultaneously without interference.

Security
The VC8 is the best charger I've owned. The included 3500mAh cells are a bonus. I use the capacity grading feature constantly.
My high-drain lights and lasers use these 18650s. The VC8 keeps them topped up and tells me when they're getting weak.
You get a top-tier 8-bay tester and two excellent 3500mAh cells. Great way to start a battery collection.
I ran the capacity test on the VC8 and got 3480mAh. The charger is a workhorse, and the batteries are solid.
The batteries are perfect for my dual-cell mod. The VC8 ensures they are matched. A professional solution.
