18650 lithium battery discharge effect

  • Common rechargeable 18650 lithium battery, standard voltage is 3.6 or 3.7v, when full power is 4.2v, which with electricity (capacity) has little relationship, 18650 mainstream capacity from 1800mAh to 2600mAh, (18650 battery capacity more in 1200 ~ 1600mAh), the capacity of even the mainstream standard 3500 or 4000mAh imported lithium batteries have more. Is generally believed that the no-load voltage into 3.7V lithium batteries run out of power is considered a no-load voltage discharge lithium batteries can not be put 3.7V or less, otherwise it will damage the battery over-discharge battery charge is 4.2V maximum voltage limit, general think the no-load voltage lithium battery charge is considered to 4.2V power full battery charging process, the battery voltage is gradually increased to the no-load voltage 3.7V 4.2V rechargeable lithium battery can not be charged to 4.2V or more, otherwise it It will damage the battery, the lithium battery which is a special place.
    18650 lithium battery discharge Benefits: The battery is its internal resistance of the battery during use and magnitude of the current, temperature, etc. to determine the size.
    Usually lithium-ion battery is different from the old "memory cell" lithium-ion batteries in the market, the formation of the old battery replacement, both because of the lithium-ion batteries have no memory benefit, but also because the lithium-ion battery of environmental protection, lightweight and easy to carry, but also because the lithium-ion greater discharge efficiency of the battery.
    However, the most fundamental discharge efficiency lithium-ion battery is a lithium ion battery with the use of raw materials related to the choice of quality raw materials to reduce the internal resistance of the battery charge and discharge efficiency of different anode materials of lithium batteries is also a difference.
    Removing their own internal friction damping cell (this can not be avoided), the battery will vary according to the case of using the environment.
    Therefore, we recommend using 18650 lithium were carried out at the optimum temperature.
