Application:
Smart devices:
Suitable for devices with moderate battery life requirements such
as fingerprint locks, cervical massagers, microphones, etc. The
battery has a standard voltage of 3.7V and supports working in an
environment of -10~60℃. The cycle life is up to 500 cycles, which
can meet daily use needs.
Consumer electronics:
Can be expanded to small household appliances such as aromatherapy
machines and beauty devices. Its lightweight design (10×20×40mm)
and low-temperature working characteristics (-10℃ start-up) are
suitable for outdoor scenes in winter.
Industrial scene:
Outstanding performance in medical equipment (such as detectors,
scanning pens). The battery has high consistency and low
self-discharge characteristics (monthly self-discharge rate ≤5%),
and can maintain stable performance after long-term storage.
How to make sure the qualtiy:
A-grade battery cells:
Use high-quality raw materials, sufficient capacity, long battery
life, safe and non-explosive, non-inflating, and fully automated
manufacturing.
High-performance protection board
Use high-strength protection board, stable voltage output to
support current (use protection board according to battery output),
prevent overcharging, over-discharging, and short circuit.
International standard lead wire:
Use high-quality wire, strong conductivity, not easy to break, can
support high-probability discharge.
Wide nickel tabs:
Use high-quality tabs, good thermal conductivity and electrical
conductivity, reduce heat generation, and stable current output.
