Product Description
Solar Lithium Cell 802040 3.7V 650mAh Rechargeable Lithium Ion Polymer Battery For Bauty Device

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.
