Description
Elevate your high-drain flashlights with the Wurkkos 26650 5000mAh flat rechargeable lithium-ion battery – a powerful flat-top cell engineered for exceptional runtime and reliable performance in demanding applications. This battery boasts a normal capacity of 5000mAh at 0.5C (with a minimum capacity of 4950mAh at 0.5C discharge from 4.2V to 2.75V), paired with a normal voltage of 3.6V for stable and consistent power delivery.
The flat-top design ensures broad compatibility with flashlights and devices that accept unprotected or flat-top 26650 cells, providing secure contact and easy integration as a high-capacity upgrade.
Detailed specifications:
- Normal capacity: 5000mAh @ 0.5C
- Minimum capacity: 4950mAh @ 0.5C (discharge from 4.2V to 2.75V)
- Normal voltage: 3.6V
- Charging voltage: 4.2V ± 0.05V
- Discharge ending voltage: 2.75V ± 0.05V
- Standard charging current: 0.5C (2500mA)
- Standard discharge current: 1C (5000mA)
- Maximum charge current: 1C (T ≥ 10℃); 0.2C (0℃ ≤ T < 10℃)
- Maximum continuous discharge current: 3C (23℃ ≤ T ≤ 27℃)
- Maximum pulse discharge current: 5C (23℃ ≤ T ≤ 27℃)
- Recommended charge/discharge temperature: Charge: 0℃~60℃; Discharge: -20℃~60℃
- Maximum short-term allowable temperature: Charge: 60℃; Discharge: 75℃ (shortened cycle life at these limits)
- Internal resistance: ≤20mΩ (AC Impedance, 1000Hz)
This high-capacity 26650 cell excels in scenarios requiring long runtimes and moderate to high current draw, such as powerful LED flashlights, search lights, or other compatible gear. Its low internal resistance supports efficient power transfer, while the wide temperature range ensures dependable operation in varied outdoor conditions.
Important safety and usage notes: Charge only with a compatible lithium-ion charger supporting 26650 cells and the specified CC-CV method (to 4.2V ± 0.05V). Do not exceed recommended currents, temperatures, or discharge limits. Avoid short-circuiting, puncturing, crushing, over-discharging below 2.75V, or exposing to water, fire, or extreme conditions beyond short-term allowances. Use in devices with appropriate protection circuits (critical for high-drain or unprotected setups). Store in a cool, dry place, partially charged. Follow charging guidelines to preserve cycle life.
Upgrade to superior capacity and performance with the Wurkkos 26650 5000mAh flat – more power, longer illumination, and trusted reliability!
