How to make sure the quality?
1. A-grade battery cell:
Using lithium battery raw materials from major industry brands, they have sufficient capacity, low internal resistance, long battery life, no inflation, and are manufactured using fully automated processes.
2. High-performance protection board:
Adopt high-strength protection board, stable voltage output, with charge and discharge overcurrent protection, short circuit protection and temperature protection, to prevent overcharge and overcurrent from damaging the battery.
3. High-quality silicone cable:
Using high-quality environmentally friendly wire, it is flexible and not easy to break. Different models of wires can be selected according to customer needs to meet different power discharges and prevent safety accidents.
Application:
MP3/MP4 player: As a mainstream portable device battery, it provides long-term battery life support.
GPS tracker: Used for outdoor positioning equipment, requiring stable power supply performance.
Bluetooth headset/speaker: Adapt to wireless devices, emphasizing lightweight and long battery life.
Storage precautions for lithium polymer batteries:
Temperature and humidity: The ideal storage temperature is 15-25℃. Avoid high temperature (＞35℃) or humid environment. High temperature will accelerate battery aging, and humidity may cause short circuit or corrosion.
Power management: It is recommended to keep the power at 50% for long-term storage, and avoid full charge or over discharge. Regular charge and discharge cycles can maintain battery health.
Isolation and protection: Keep away from fire and flammable materials. Use fireproof containers or fireproof bags when storing, and ensure good ventilation.
Certification:
CE, ROHS, MSDS, UN38.3, 1.2m drop testing, IEC62133, Ect...
Warning:
Danger warning(it should be described in manual or instruction for users, indicated especially) to prevent the possibility of the battery from leaking, heating, explosion. Please observe the following precautions:
Don't immerse the battery in water and seawater. Please put it in cool and dry environment if no using
Do not discard or leave the battery near a heat source as fire or heater
Being charged, using the battery charger specifically for that purpose
Don't reverse the positive and negative terminals
Don't connect the battery to an electrical outlet directly
Don't connect the positive and negative terminal directly with metal objects such as wire. Short terminals of battery is strictly prohibited, it may damage battery
Do not transport and store the battery together with metal objects such as necklaces, hairpins
Do not strike, throw or trample the battery
Do not directly solder the battery and pierce the battery with a nail or other sharp object
Do not use it with other different battery, or other different lithium polymer battery model in mixture
Prohibition of use of damaged cells
Don't bend or fold sealing edge. Don't open or deform folding edge. Don't fillet the end of the folding edge
Don't fall, hit, bend battery body
Battery pack designing and packing Prohibition injury batteries
Never disassemble the cells
The battery replacement shall be done only by either cells supplier or device supplier and never be done by the user
Keep the battery away from babies
Any components contacting these two edges, they must be insulated
