18650 Lithium Battery 2500mah 10C 18650 10c li ion Battery For Car

18650 lithium battery (Li-ion, Lithium Ion Battery): Lithium battery has the advantages of light weight, large capacity, no memory effect, etc. The energy density of lithium ion battery is very high, and its capacity is 1.5 ~ of the same weight of Ni-MH battery. 2 times, and has a very low self-discharge rate. In addition, lithium-ion batteries have almost no “memory effect” and do not contain toxic substances.
They are widely used in various electronic fields: often used in high-end glare flashlights, portable power supplies, wireless data transmitters, electric thermal clothing, etc.

1.Before testing or using the battery, please read this specification carefully to prevent improper operation from causing battery failure, heat generation, leakage, fire or even explosion; abuse in violation of the usage conditions in this specification is strictly prohibited.
2.When charging and discharging the battery, please use special testing equipment for lithium-ion batteries. It is strictly forbidden to use ordinary constant current and constant voltage sources and other devices that cannot limit voltage and current to charge and discharge the battery to prevent the battery from being overcharged and overdischarged. Function failure or danger.
3.When charging and discharging the battery or inserting the battery into the device, be careful not to reverse the positive and negative poles of the battery, otherwise the battery will be overcharged and over-discharged, causing serious battery failure or even explosion hazards.
4.Do not weld the battery directly, and it is strictly forbidden to disassemble the battery.
5.Do not put the battery in your pocket or bag with metal items such as necklaces, hairpins, coins or screws, and do not store the battery with the above items. It is strictly forbidden to use metal or other conductive materials to directly connect the positive and negative poles of the battery to make the battery A short circuit occurred.
