3.7v 3000mah 18650 battery

　　What should we pay attention to when using lithium batteries?

　　Discharge: For first time use, please apply the standard balanced charging head to charge the battery; the first application of a new rechargeable battery avoids excessive charging and discharging. After the first application, the chip working voltage (lithium batteries are composed of multiple cells, such as , composed of three lithium-ion batteries, so it is called 3S lithium battery) should not be less than five cycles after continuous use. During continuous use, attention must be paid to checking the voltage of the battery. The total working voltage of a 3-string lithium battery pack should not be less than that of a 2-string lithium battery pack. The working voltage of a single bead should not be less than. Less than this rated current will cause the rechargeable battery to bulge until it is damaged, causing power loss, which may cause damage to the rechargeable battery!

　　Storage: Lithium-ion batteries have a longer service life than nickel-metal hydride rechargeable batteries. They are easily overcharged and discharged after long-term storage. Please maintain the working voltage regularly and keep a single working voltage in the middle; Storage standards: temperature -20c-35c; air humidity 45%- 85%.

　　Polymer lithium battery cells should be packaged with aluminum plastic film to avoid scratching, impacting or using sharp objects to break the battery surface. The pinna of the rechargeable battery is not very strong and can easily break when bent, especially for normal ears. The polymer lithium battery pack has been carefully welded to prevent cracks or re-welding. Polymer lithium theoretically will not move lithium battery electrolyte, but if there is leakage of lithium battery electrolyte and it touches the skin, eyes or other human body parts, you should immediately rinse with cold water and consult. It is strictly prohibited to use rechargeable batteries that have been destroyed. If a rechargeable battery burns, do not recharge the battery to avoid excessive damage.
