What is the 24-hour self-discharge test?

The self-discharge test of lithium battery is: generally use 24-hour self-discharge to quickly test its charge retention capacity, discharge the battery to 3.0V at 0.2C, charge it to 4.2V at constant current and constant voltage 1C, cut-off current: 10mA, set aside for 15 After one minute, discharge the battery at 1C to 3.0V to measure its discharge capacity C1, then charge the battery with constant current and constant voltage 1C to 4.2V, cut-off current: 10mA, and measure 1C capacity C2 after 24 hours of rest, C2/C1*100% should be greater than 99%.

What certifications have the company's products passed?

Has passed ISO9001: 2000 quality system certification and ISO14001: 2004 environmental protection system certification; products have obtained EU CE certification and North American UL certification, passed the SGS environmental protection test, and have obtained Ovonic's patent license; At the same time, the company's products have been approved by PICC in the world Coverage.

What precautions should be taken when using the battery?

01) Please read the battery manual carefully before use;

02) Electrical appliances and battery contacts should be cleaned, wiped with a damp cloth if necessary, and installed according to the polarity mark after drying;

03) Do not mix old and new batteries, and batteries of the same type but different types cannot be mixed, so as not to reduce the use efficiency;

04) Disposable batteries cannot be regenerated by heating or charging;

05) The battery cannot be short-circuited;

06) Do not disassemble and heat the battery, or throw the battery into water;

07) When the electrical appliance is not used for a long time, the battery should be taken out, and the switch should be turned off after use;

08) Do not discard waste batteries at will, and place them separately from other garbage as much as possible to avoid polluting the environment;

09) When there is no adult supervision, do not allow children to replace the battery, and the small battery should be placed in a place that children cannot reach;

10) The battery should be stored in a cool, dry place without direct sunlight.
