Equip your flashlights with consistent, high-density power using the Wurkkos 18650 3000mAh button top rechargeable lithium-ion battery – a reliable button-top cell sold as 1 battery per pack for easy single buys, spares, or precise replacements. With a nominal voltage of 3.6V and impressive energy density of 245 Wh/kg, this battery delivers excellent runtime and efficient performance in a wide variety of 18650-compatible torches and devices.

The button-top configuration ensures broad compatibility with flashlights, mods, and equipment designed for unprotected or button-top 18650 cells, providing stable contact and straightforward installation. Engineered for balanced charging and discharge behavior across temperature ranges, it supports higher currents in optimal conditions while protecting longevity at temperature extremes.

Core specifications:

• Nominal voltage: 3.6V
• Charge voltage (end current): 4.20V ± 0.05V (cut-off at 31mA; avoid >4.20V for cycle life)
• Discharge cut-off voltage: 2.5V (minimum, T ≥ 20℃)
• Energy density: 245 Wh/kg
• Maximum charge current:
  • 1C (3100mA) at 25℃–45℃
  • 0.5C (1550mA) at 15℃–25℃
  • 0.33C (1023mA) at 10℃–15℃
  • 0.15C (465mA) at 0℃–10℃
• Maximum discharge current:
  • 1C (3100mA) at 45℃–60℃
  • 3C (9300mA) at 20℃–45℃
  • 2C (6200mA) at 5℃–20℃
• Temperature guidance: Higher currents permitted in optimal ranges; reduced limits at lower/higher temperatures to maintain safety and cycle life

This cell shines in moderate to higher-drain flashlights, offering solid capacity paired with robust discharge capability for brighter beams and extended use. Its high energy density maximizes power in the compact 18650 format, making it a smart choice for EDC, tactical, or outdoor lighting needs.

Important safety and usage notes: Charge exclusively with a quality lithium-ion charger supporting CC-CV to 4.20V ± 0.05V (31mA cut-off). Strictly respect temperature-dependent maximum currents to avoid reduced lifespan or safety risks. Never short-circuit, puncture, crush, over-discharge below 2.5V, or expose to water, fire, or conditions outside recommended ranges. Use in devices with suitable protection circuits (highly recommended for higher-discharge applications). Store partially charged in a cool, dry environment.

Note: This listing is for 1 battery per pack – perfect for individual needs or building your setup.
