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.
