3.7V Battery 18650 is widely used because of their light weight, large capacity, and no memory effect. Many digital devices use lithium-ion batteries as power supplies, although they are relatively expensive. Lithium-ion batteries have a high energy density, and their capacity is 1.5 to 2 times that of nickel-hydrogen batteries of the same weight, and has a very low self-discharge rate. In addition, the lithium-ion battery has almost no "memory effect" and does not contain toxic substances, which is also an important reason for its wide application.
1)High energy density
2)High working voltage for single battery cells
3)Pollution-free4)Long cycle life
5)No memory effect
6)Capacity, resistance, Voltage, platform time consistency is good
7)With short-circuit production function, safe and reliable
8)Factory price& High quality
9)Good consistency, low self discharge
10)Light weight, small and customized size
11)Wide application for electronics and industry
Never completely discharge li-ion battery ( below 2.7V under load ).
Charge fully to 4.2V before first use.
Never use force to install (insert) li-ion battery.
Do not use old and new battery cells together.
Use only high quality battery charger.
Do not expose to heat.
Do not short (connect) positive (top), and negative (bottom) battery terminals (contacts). Keep battery that is not in use in plastic holder (or any insulating [plastic] container).
Do not charge battery over 4.29V (another reason to use high quality battery charger).
Do not charge unattended.
Do not use old, and new cells together.
Do not store your li-ion batteries fully charged (for extended period of time).
Store in cold and dry place at approximately 3.7V (storage charge).
After battery is discharged-don't leave it discharged=>charge it as soon as possibl
