Product Description:
Power up your daily essentials with our premium 14500 3.7V 750mAh Rechargeable Li-ion Button Top Batteries. Designed to deliver reliable, long-lasting energy, this 10-pack ensures you always have a fresh battery on hand for all your standard electronic devices.
These batteries feature a high-capacity 750mAh rating and a convenient Button Top design, ensuring a secure and stable connection with spring-loaded battery compartments in most flashlights, toys, and headlamps. Engineered for consistent voltage output, they are an eco-friendly, cost-effective alternative to disposable alkaline batteries (when used with a 14500-compatible dummy spacer).
Important Note: This is a Button Top battery (Height approx. 50mm). Please check your device to ensure it does not strictly require a "Flat Top". These batteries are NOT recommended for high-drain devices (such as high-power drones, power tools, or high-wattage vaporizers) that exceed their safe discharge limit.
Key Features:
High Capacity 750mAh: Provides longer runtime for your LED flashlights, headlamps, and small electronics.
Button Top Design: Ensures better contact with battery springs, making it universally compatible with most 14500 battery slots.
Reliable & Stable Voltage: Built with quality Li-ion chemistry to provide steady 3.7V output until the end of the discharge cycle.
Eco-Friendly & Economical: Rechargeable up to 150+ cycles, significantly reducing waste and saving money versus single-use batteries.

FAQ:
Q: What is the difference between "Button Top" and "Flat Top"?
A: A Button Top battery has a small raised button on the positive end. Our 14500 is a Button Top, which is designed to fit most standard flashlight and toy battery compartments that have spring contacts. Flat Tops are usually shorter and may cause a loose connection in these devices.
Q: What is the maximum discharge current of this battery?
A: These batteries are designed for standard to moderate discharge applications (typical for flashlights). Please ensure your device's current draw does not exceed the battery's safe limit. They are NOT intended for high-drain power tools or heavy-duty drones.
Q: Can I charge this battery in a standard AA Ni-MH charger?
A: No. You MUST use a dedicated 3.7V / 4.2V Li-ion battery charger. Using a Ni-MH charger can be dangerous.
Q: Can I use this to replace my 1.5V AA alkaline battery?
A: Lithium-ion 14500 batteries have a voltage of 3.7V. You CANNOT directly replace a 1.5V AA battery without ensuring your device supports the higher 3.7V voltage. We recommend checking the device specifications or using a dummy spacer if voltage reduction is needed.
