3.7V 2200mAh 18650 Low Temperature Cell

3.7V 2200mAh 18650 low temperature Cell: -40℃ 1C Discharge, Puncture-Safe

Introduction 

• Delivers 2200mAh capacity, 3.7V stability, and -40℃ 1C discharge (≥70% capacity retention).
• Charges in 0~45℃ (vs. ordinary 18650s’ 5℃ min) — no downtime in freezing storage.
• Supports 2.2A symmetric charge/discharge — refuels 2200mAh in 2 hours, powers 8W devices at -40℃.
• Passes puncture and shooting tests — safe for human-worn gear (heated vests) and explosive cold zones (gas pipelines).

Why It Dominates Cold Environments 

1. -40℃ 1C Discharge

• “1C Discharge at -40℃: This 18650 low temperature cell retains 70% capacity (1540mAh) — powering Arctic drones for 30+ mins. Ordinary 18650s fail at -20℃.”

2. 0℃ Charging Capability

• “0℃ Charging: Recharges in freezing cold storage where ordinary 18650s (5℃ min) stall — critical for cold-chain sensor uptime.”

3. 2.2A Symmetric Charge/Discharge

• “2.2A Continuous Current: Refuels 2200mAh in 2 hours (ideal for military gear), discharges 2.2A to run 8W devices at -40℃ — no voltage sag.”

4. Puncture & Shooting Test Compliance

• “Puncture/Shooting Test Pass: Safe for human-worn heated vests and explosive cold zones (e.g., gas pipelines) — a 18650 low temperature battery built for danger.”

Application Scenarios 

1. Arctic Exploration & Military

• “Polar Research: 18650 low temperature cells power ice-core drills and -40℃ drones — 2200mAh supports 12+ hours of data collection.”
• “Military Gear: 2.2A charge refuels night-vision goggles in 2 hours — ready for -30℃ missions with 70% capacity retention.”

2. Cold-Chain Logistics

• “Cold Storage Sensors: 70% capacity at -40℃ (1C) keeps trackers running 12+ hours — ensuring vaccine integrity in -30℃ transport with low temp 18650 batteries.”

3. Outdoor & Winter Sports

• “Winter Sports Tech: Powers smart goggles and heated vests — 2-hour recharge between runs, even in -10℃ ski resorts with 18650 low temperature cells.”
