Frequently Asked Questions (FAQ)
Q1: What is included in this bundle?
A1: The bundle includes one XTAR VC4 4-slot charger, one USB charging cable, one storage pouch, a user manual, and either 1 or 2 units of the XTAR 14500 800mAh 4.5A batteries based on your variant selection.
Q2: Is this 14500 battery compatible with the VC4 charger?
A2: Yes. With a diameter of 14.3mm and a height of 50.5mm, this compact 14500 battery fits securely into the VC4 charger's spring-loaded slots and will charge efficiently.
Q3: What is the maximum charging current of the VC4 charger?
A3: The XTAR VC4 offers two adjustable charging currents: 0.5A and 1.0A. It supports up to a 1.0A charging current per slot when charging four batteries simultaneously.
Q4: Can I charge Li-ion and Ni-MH batteries at the same time?
A4: Yes. The VC4 features independent 4-slot circuitry, allowing you to safely mix 3.6V/3.7V Li-ion batteries and 1.2V Ni-MH batteries in different slots.
Q5: How does the "0V Activation" feature work?
A5: If your lithium battery has been over-discharged to an extremely low voltage (near 0V), the VC4 will apply a safe, low current to gently reactivate the battery's internal protection circuit, often successfully restoring it to a chargeable and usable condition.
