Advantages:
Safety:
Using an aluminum-plastic flexible packaging structure, compared to liquid-cell metal casings, this battery only bulges in the event of an abnormality, rather than explodes, providing enhanced safety.
Thin and Light Features:
With a thickness of less than 5mm and a weight of only 20g, it's suitable for space-constrained devices (such as navigation systems, Bluetooth speakers, and beauty devices), and is less susceptible to bulging or overheating.
Battery Life:
Tested continuous operation lasts a full day. When the battery is depleted, the voltage drops steadily, preventing device freezes or sudden power outages.
Charging Efficiency:
Supports Type-C fast charging, fully charging in 2 hours, meeting the needs of frequent daily use.
Operating Stability:
Wide operating temperature range (-20°C to 65°C), it provides stable power even in outdoor temperatures of -5°C, making it suitable for use in cold northern regions.
Cycle Life:
Using polymer cells, the battery boasts a cycle life of over 300 cycles (with capacity retention ≥80%), surpassing the durability of some liquid-cell batteries.
Application:
Bluetooth Speakers:
This battery is widely used as an upgrade or replacement for Bluetooth speakers. For example, models produced by Hengxin Battery can support continuous playback all day long, with stable voltage and no lag when the battery is depleted.
Navigation Systems and Car Devices:
Due to its compact size and moderate capacity, the 503040 battery can be embedded in the back of a navigation system. It has been tested to operate stably in low-temperature outdoor environments (-5°C).
Beauty Devices:
This battery is used in devices such as beauty devices that require long-term operation, such as removing blackheads and performing facial treatments, ensuring full power supply.
Children's Storytelling Machines:
Replacing the original battery significantly improves the device's battery life. The polymer material is highly safe, preventing bulging or overheating.
Other Applications:
Some users have tried using this battery in DIY devices such as handheld fill lights and mini projector power supplies. Due to its high energy density and fast charging (full charge in 2 hours via Type-C port), it is highly adaptable.
