18650 lithium-ion battery, C5, 3.7V, 2000mAh, 20A discharge, used for power tools, communication, medical, etc Product parameters: model: inr18650-C5 Voltage: 3.7V Storage temperature: room temperature Material: Lithium ion Size: 65 * 18mm Nominal voltage: 3.7V Charging voltage: 4.2V Continuous discharge current: maximum 30A Continuous charging current: maximum 4A Note: Do not wait until the battery is depleted before charging. Lithium batteries are different from ordinary batteries. Charging the battery before use is not conducive to the health of lithium batteries. Battery depletion may lead to charging failure 2. Do not place lithium batteries at high temperatures. Lithium batteries prefer low temperatures. 3. Summary of Charging Methods: Short Circuit Charging and Short Circuit Charging (Charging is not frequent, but if you want to speed up!) 4. Charging time when the power supply drops to 10 hours and 20% 5. Use high-quality specialized lithium battery chargers with protective functions In low-temperature weather, the lifespan of lithium batteries will be greatly shortened. This is normal, it will return to a warm place in about an hour. Widely used: electronic cigarettes, power tools, electric vehicles, electrical equipment, flashlights, electronic cigarettes, power tools, drones, airplane models, electric vehicles, communication, medical, etc
