The circular lithium battery refers to the cylindrical lithium battery The earliest cylindrical lithium battery is the 18650 lithium battery invented by SONY in 1992.

Recently, Ms Xu, who lives in Jiangnan  City, called the citizen assistance center’s duty room.

A, Power battery propaganda may fool youWhen a lot of mobile power supply manufacturer in advertising products will often emphasize their batteries is high quality polymer batteries, safety performance is better than the other brands of batteries, and give a lot of shocking batteries "explode" photos, so concerned about what the product is safe and consumers how to choose?Mobile power battery depth resolution - 18650 cells more easily?Because there is no related professional knowledge, consumers in the choose and buy mobile power supply when the propaganda effect is more vulnerable to the manufacturer.

When is electric vehicle possible for fire?Night more than half of the electric fire occurred in the process of charging at nightAccording to the previous case, the electric fire casualty charging commonly occur in the evening.

Lithium ion battery has the following advantages:1) high voltage, monomer battery working voltage is 36-3.

Using a multimeter red pens to connect anode and black pens for cathodeGear in 50 V, dc 12 V battery put after the power is 105 V, after full is 14.

A, You had better choose smart socketMany of the lithium battery electric vehicle charging user home, at work the next day to cut off the power supply, in fact most chargers cannot guarantee one hundred percent in lithiumThe battery automatically when full of electricity.

At the initial power-on, capacitor C1 is charged through 10K resistor R1, and the C1 potential rises slowly from low level to Vcc and stabilizes When the power is off, the potential of C1 is close to Vcc, and it is discharged to the Vcc power supply terminal of the IC through two paths; one way is discharged through R1, and one way is quickly discharged through the diode.

Lithium-ion batteries, we are referred to as lithium batteries on weekdays In daily life, lithium batteries are closely related to the use of mobile phones and laptops.
