Selling Points:
Balanced Capacity & Compact Size: With 600mAh capacity and 2.22Wh
energy, it strikes a perfect balance between runtime and size
(6×25×40mm)—ideal for devices needing longer than mini batteries
(e.g., 200mAh) but limited by thin/light design.
High Energy Density: Delivers ~370Wh/L energy density (calculated
by 2.22Wh ÷ 6cm×2.5cm×4cm),outperforming traditional cylindrical
batteries of similar volume, saving internal space for device
integration.
Reliable Safety Performance: Soft-package Li-Polymer structure +
built-in protection IC (against overcharge, over-discharge, short
circuit, and overcurrent),effectively preventing swelling or
thermal risks, meeting consumer electronics safety standards.
Long-Term Durability: Supports 300–500 charge-discharge cycles (at
0.5C charge/discharge rate, 25℃),maintaining over 80% capacity
after 300 cycles—reducing replacement frequency for long-term use
devices.
Wide Temperature Adaptability: Operates stably in -10℃~60℃
(discharge) and 0℃~45℃ (charge),suitable for indoor/outdoor devices
(e.g., outdoor wearables, portable medical tools) under varying
environmental conditions.
Low Self-Discharge: Loses only ~5% capacity per month at room
temperature,ensuring devices (e.g., backup sensors) remain usable
even after long storage without frequent recharging.
Key Features:
Physical Specifications: Dimensions 6mm (thickness) ×25mm (width)
×40mm (length),weight ~12–15g (typical),thin and flat design fits
slim device casings (e.g., smart bracelets, thin sensors).
Electrical Parameters: Nominal voltage 3.7V (working voltage range:
3.0V–4.2V),capacity 600mAh (0.2C discharge, 25℃),energy
2.22Wh—matches the power demand of medium-power small electronics.
Charging Performance: Compatible with 0.5C–1C fast charging (max
charge current 600mA),reaches 80% capacity in ~1 hour (with
matching charger),improving user convenience.
Structural Design: Flexible aluminum-plastic film packaging,can be
slightly bent (within 5°) to adapt to irregular device inner
structures (e.g., curved smart glasses frames) without performance
loss.
Environmental Compliance: RoHS-certified (free of lead, mercury,
and other harmful substances),meets global environmental standards
for consumer and medical electronics.
Main Application:
Mid-Size Wearable Devices: Advanced smart bracelets (with heart
rate + blood oxygen + GPS), smart glasses (lightweight AR models),
fitness armbands.
Portable Medical Equipment: Handheld pulse oximeters (for
home/community use), mini portable blood pressure monitors, small
insulin coolers.
IoT & Smart Sensors: Wireless temperature/humidity sensors (for
smart agriculture/warehouses, 1–2 months of use per charge),
Bluetooth gateways (for smart homes, low-power standby), asset
tracking tags (for logistics, long standby + compact size).
Consumer Electronics: High-capacity wireless earbud charging cases
(supports 2–3 full charges for earbuds), mini digital voice
recorders (portable + long recording time), thin portable LED
lights (outdoor camping, lightweight).
Outdoor & Emergency Devices: Mini GPS locators (for children/pets,
3–5 days of standby), small emergency power banks (for charging
smartphones in urgent situations), portable laser pointers (for
presentations, long battery life).
