Common guidelines for square lithium-ion batteries

Tips for maintaining lithium battery capacity and life:

One, if you use external power supply for a long time to power the laptop, or the battery power has exceeded 80%, immediately remove your laptop battery, usually do not need to charge the battery is full, charge to about 80%; High speed operating system power options, the power alarm will be set to more than 20%, usually the battery power should not be less than 20%.

Two, no matter to notebook or mobile phone, must not let the battery run out.

How do you tell a lithium battery from a lithium battery?

1, Look at the plastic surface and plastic material. Really uniform anti-wear surface of the battery, the use of PC material, no brittle phenomenon; Fake battery without anti-wear surface or too rough, using recycled material, easy to crack.

2. Compare the battery capacity. A typical nickel-cadmium battery is 500mAh or 600mAh, and a nickel-hydrogen battery is 800-900mah. Lithium ion cell phone battery capacity is generally between 1300 and 1400mAh, so lithium battery full power after the use of time is about 1.5 times that of nickel hydrogen battery, nickel cadmium battery is about 3.0 times. If you find that the lithium ion mobile phone battery block you purchased does not work for the long time advertised or specified in the instructions, it may be counterfeit.

Advantages of polymer lithium ion batteries:

1. Polymer lithium battery with good safety performance adopts aluminum plastic flexible packaging in structure, which is different from the metal shell of liquid battery cell. Once there are safety risks, liquid battery cell is easy to blow up, while polymer battery cell can only blow up at most.

2. The capacity of large polymer battery is 10-15% higher than that of steel shell battery of the same size and specification, and 5-10% higher than that of aluminum shell battery. It has become the primary choice of color screen mobile phone and MMS mobile phone.
