AAA Battery 3x1.5V Storage Adapter Case with 18650 Battery Holder Converter for AAA LED Flashlight

Plastic Battery Holder tailored for 3 AAA batteries, designed specifically for flashlight use. When three AAA batteries are connected in series, they output a steady 4.5V voltage, ensuring reliable power for your flashlight.

Many flashlight models are equipped to accommodate either a single 18650 battery or a 3xAAA battery holder. Notably, the 3xAAA battery holder boasts a larger diameter than the 18650 battery, offering versatility in power source options.

Using a single 18650 battery in the flashlight may result in it moving loosely within the compartment. To address this, battery converters prove invaluable, effectively increasing the diameter of 18650 batteries for a snug fit in flashlights. Simply insert one of these sleeves to minimize any unwanted movement.

Moreover, aside from ensuring a secure fit, the sleeve also serves as a protective barrier, preventing potential impacts between the battery and the inner wall of the flashlight, thus safeguarding the battery from damage.

Please take note: Batteries are not included. Before selecting a battery holder for your flashlight, it's essential to verify the required diameter of the sleeve for compatibility and optimal performance.
