HL18650F High Discharge Battery Performance Validation
30A High-Rate Discharge Capability
HL18650F supports up to 30A discharge, delivering approximately 2.1Ah at 20A. Temperature rise increases at higher discharge currents.
High-Rate Discharge at −40°C
HL18650F delivers approximately 2.3–2.5Ah at −40°C across discharge currents from 0.6A to 6A, demonstrating reliable cold-weather power output.
Wide-Temperature Discharge Performance
The 3000mAh HL18650F wide-temperature cell delivers approximately 2.35Ah at −40°C and 2.9Ah at temperatures from 25°C to 85°C.
Capacity Retention After 80°C Aging
After 30 days of aging at 80°C and 4.05V, HL18650F retains approximately 92% of its initial discharge capacity.
High-Temperature Cycle Life at 60°C
HL18650F retains approximately 85% capacity after 500 cycles at 60°C under 1C charge and 1C discharge conditions (4.2–2.5V).
Cycle Life at Room Temperature
HL18650F retains approximately 88% capacity after 500 cycles at room temperature under 0.5C charge and 15A discharge conditions.
Why Conventional 18650 Batteries Fail
