SPERAS PB38 18650 3800mAh Lithium Battery (20A HDC)

Power your high-performance tactical and outdoor flashlights with the SPERAS PB38. Delivering a massive 3800mAh capacity and a 20A maximum discharge current, this premium 18650 cell ensures your gear runs brighter and longer when you need it most.

Unleash the Full Potential of Your Flashlight

Standard batteries often suffer from voltage sag under heavy loads, causing high-lumen flashlights to step down in brightness prematurely. The SPERAS PB38 is engineered with High Drain Current (HDC) chemistry, allowing it to push up to 20 Amps safely. This guarantees sustained turbo modes and maximum beam distance for your tactical equipment.

Massive 3800mAh Capacity

Extended runtimes for long hunting trips, camping nights, or emergency shifts. Spend less time charging and more time illuminating the dark.

20A Max Discharge (HDC)

Designed specifically for high-drain devices. Easily handles the intense power draw of modern LED emitters without overheating or failing.

Frequently Asked Questions (FAQ)

What does 20A HDC mean?

HDC stands for High Drain Current. It indicates that the SPERAS PB38 can safely deliver up to 20 Amps of maximum current. This is crucial for ultra-bright tactical flashlights that require massive energy to sustain their highest lumen outputs without dropping voltage.

Does this battery have a built-in USB charging port?

No, the PB38 model focuses entirely on maximizing capacity (3800mAh) and output current. It does not feature a built-in USB port. To recharge it, you should use a dedicated lithium-ion battery charger or place it inside a flashlight that has built-in charging capabilities.

Is the PB38 compatible with all 18650 flashlights?

With a standard diameter of 18.45mm and a length of 69.1mm, the PB38 is widely compatible with most high-end flashlights designed for standard 18650 cells. Always check your device specifications to ensure it accepts standard length 18650 batteries.
