FAQ
Q1: What is the difference between Button Top and Flat Top?
A: Flat Top has a flat positive terminal, compatible with most modern devices (flashlights, DIY packs, fans). Button Top has a raised positive terminal (like a standard AA battery), required for older devices and certain flashlights with spring-loaded contacts. Please select your desired version when placing your order.
Q2: What devices is this battery compatible with?
A: This 18650 battery is compatible with hundreds of devices that require a 3.7V lithium-ion cell. Common applications include headlamps, LED flashlights, portable fans, digital cameras, toys, radios, and surveillance devices. Always check your device's battery compartment to ensure it supports 18650 cells.
Q3: What does 4.4A mean?
A: 4.4A refers to the maximum continuous discharge current of this battery. This means it can safely deliver up to 4.4 amps of power continuously. This makes it suitable for medium-drain devices like bright flashlights and fans, but not recommended for high-power applications like vaping or heavy power tools.
Q4: How many times can this battery be recharged?
A: This battery can be recharged approximately 800 times, depending on usage and charging habits. Proper care (using a quality charger, avoiding full discharge, and storing at moderate temperatures) will extend its lifespan.
Q5: What charger should I use?
A: Use a dedicated intelligent Li-Ion charger designed for 3.7V/4.2V cells. Do not use universal chargers designed for NiMH batteries. Look for chargers with features like overcharge protection, temperature monitoring, and cell balancing if charging multiple cells.
Q7: How do I identify positive and negative terminals?
A: The flat top (or the raised button on button top version) is the Positive (+) terminal. The bottom (the side with the shiny metal casing and a slight indentation) is the Negative (-) terminal.
Q8: How should I store this battery when not in use?
A: Store at a partial charge (around 40-60% capacity) in a cool, dry place away from direct sunlight and extreme temperatures. Do not store fully charged or fully depleted for extended periods.
