Frequently Asked Questions (FAQ)
Q1: What are the available pack options for this battery?
A1: You can purchase this battery in 1, 2, 3, 4, 5, or 10-piece packs. Please select the desired quantity from the variant options before checkout.
Q2: Can I use this battery to replace an 18650 battery in my flashlight?
A2: No, definitely not. The 16340 battery is physically much smaller than an 18650 (16.4mm vs 18.8mm diameter, and much shorter). It will not make contact in a standard 18650 battery compartment.
Q3: Does this battery have a built-in protection board?
A3: Yes. It features an intelligent chip protection board integrated at the positive and negative poles to effectively prevent overcharging, over-discharging, and overcurrent, ensuring the safety of both the battery and your device.
Q4: What does the 0.95A discharge current mean for my devices?
A4: 0.95A discharge means this battery is designed for low-to-medium power devices, such as mini flashlights, laser pointers, and remote controllers. It is not suitable for high-wattage electronic cigarette mods or high-powered motors.
Q5: How should I charge this protected battery?
A5: It is highly recommended to use a professional smart charger (such as XTAR chargers compatible with 16340 size) with full safety protections to charge this 3.7V battery safely to its 4.2V cut-off voltage.
