18650 Rechargeable Batteries | FREE Delivery over €50 (ROI)

Power your gear with high-performance reliability using this 2-pack of protected 18650 3.7V 3500mAh Lithium-Ion batteries. Specifically engineered with a classic button-top terminal, these batteries are the ideal power source for modern high-drain flashlights, specialized electronic devices, and equipment designed for protected cells. Each unit features an integrated Protection Circuit Board (PCB) to deliver maximum safety against overcharging, overdischarging, and short circuits, ensuring long-lasting performance and consistent output through every charge cycle.

Crafted with premium components, these batteries deliver a nominal voltage of 3.6V–3.7V (peaking at 4.2V fully charged), a 5A maximum continuous discharge current, and up to 8A peak discharge.

Please Note: Because these cells feature integrated protective circuit boards, they are slightly longer than standard unprotected 18650 cells (measuring approximately Ø 18.6 mm × 38.1 mm). Please verify your device's battery compartment clearance and compatibility prior to purchase to ensure a proper fit.
