Excellent rate performance: Continuous 10A discharge at room temperature.
Wide temperature operating range: operating temperature range from -40℃ to 85℃;-40℃/0.2C can release about 75% capacity.
Excellent high temperature (80℃) storage performance: stable voltage and tiny capacity loss after 80℃/4.05V for 30days.
Excellent low temperature discharge performance after high temperature storage: after 30 days of 80℃/4.05V storage, the battery can still meet the requirements of -40℃/1C discharge.
Good cycle performance

I. Core Advantages
HL18650Y is an ultra-high temperature-resistant, wide temperature range, long cycle, and highly safe 18650 cylindrical battery cell, featuring "extreme temperature stability + long cycle durability + no capacity loss at high temperatures". It differs from ordinary consumer-grade 18650 batteries:
1. Ultra-wide temperature stability output
Discharge: -40℃ to +85℃ full temperature range available
-40℃ can still discharge ≥70% capacity, ensuring no worries for cold regions, outdoor, and cold-weather equipment
Long-term storage at 85℃, capacity retention rate ≥90%
2. High energy density + stable rate
Nominal: 3.6V / 3200mAh (typical)
Continuous discharge: 10A, peak up to 20A
High energy density, balancing between battery life and medium power requirements
3. Long cycle + low degradation
After 500 cycles, capacity ≥85%, lifespan superior to ordinary 18650
Good internal resistance consistency, low heat generation, more stable group formation
4. Safe and reliable + global certifications
Built-in explosion-proof valve, PTC protection, comprehensive protection against overcharge / overdischarge / overcurrent / high temperature
Passed international certifications such as CB, UL, CCC, BIS, PSE, KC, BSMI, etc., shipping globally is smooth
II. Application Scenarios
HL18650Y is particularly suitable for harsh environments, large temperature fluctuations, and scenarios requiring long-term stability:
