Frequently Asked Questions (FAQ)
Q1: What is included in this bundle?
A1: The bundle includes one XTAR VC4 Plus 4-slot smart charger, one USB Type-C cable, and either 1 or 2 units of the XTAR 18650 3500mAh protected button-top batteries, depending on the variant you select.
Q2: Is this battery compatible with the VC4 Plus charger?
A2: Yes. The VC4 Plus is designed to accommodate protected 18650 batteries. With a length of 69mm, this button-top battery fits perfectly and safely into the charger's slots.
Q3: What is the max discharge current, and which devices can it power?
A3: The battery supports a maximum continuous discharge current of 10A. It is suitable for most flashlights, and power banks that draw 10 amps or less. It is not recommended for heavy-duty power tools that require 20A or 30A.
Q4: What is the "Storage Mode" on the charger for these batteries?
A4: The charger's Storage Mode automatically charges or discharges the 18650 battery to its optimal long-term storage voltage of 3.7V. This prevents capacity loss and extends the battery's lifespan if you do not plan to use it for an extended period.
Q5: How can I tell if the battery is fully charged?
A5: When using the VC4 Plus charger, the LCD screen will show the charging voltage reaching 4.20V and the current dropping to less than 120mA. The slot's indicator will turn green, indicating the battery is fully charged and ready to use.
