Description
Upgrade your flashlights with dependable power using the Wurkkos 18650 3000mAh flat top rechargeable lithium-ion battery. This high-capacity flat-top cell is sold as 1 battery per pack for convenient single purchases, spares, or targeted replacements. It features a nominal voltage of 3.6V and delivers excellent energy density of 245 Wh/kg, providing balanced runtime and consistent performance in compatible 18650 flashlights and devices.
The flat-top design offers wide compatibility with flashlights and mods that accept unprotected or flat-top 18650 cells, ensuring secure contact and seamless integration. Built for reliability, it supports efficient charging and discharge across a range of temperatures and currents, making it suitable for everyday carry, outdoor use, or moderate-drain applications.
Key specifications:
- Nominal voltage: 3.6V
- Charge voltage (end current): 4.20V ± 0.05V (cut-off at 31mA)
- Discharge cut-off voltage: 2.5V (minimum)
- 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℃
- Operating temperature considerations: Higher currents allowed at optimal temperatures; reduced at extremes to preserve cycle life and safety.
This 18650 cell excels in providing solid capacity and robust discharge capability for brighter, longer-lasting illumination in compatible LED torches. Its high energy density packs more power into the standard size, while temperature-aware current limits help maintain longevity and performance in varied conditions.
Important safety and usage notes: Charge only with a compatible lithium-ion charger using the CC-CV method (to 4.20V ± 0.05V, cut-off 31mA). Do not exceed temperature-dependent max currents, short-circuit, puncture, crush, over-discharge below 2.5V, or expose to water, fire, or extreme conditions. Use in devices with appropriate protection circuits (recommended for higher-discharge setups). Store partially charged in a cool, dry place.
Note: This listing is for 1 battery per pack – ideal for singles or custom setups.
Reliable capacity and versatile performance – the Wurkkos 18650 3000mAh flat top brings high-density power and trusted quality to your lighting gear!
