18650 Rechargeable Lithium Batteries The Biggest Difference
Jun 16, 2017

    Lithium battery standard 3.7V or 4.2V are the same. Only the manufacturer is not the same as the label. 3.7V refers to the battery voltage (ie, the typical voltage) that is discharged during use of the battery, whereas 4.2 is the voltage at full charge. Common can be filled 18650 lithium battery, the voltage is standard 3.6 or 3.7v, when fully charged is 4.2v, which is not related with the power (capacity), 18650 battery mainstream capacity from 1800mAh to 2600mAh, (18650 battery capacity More than 2200 ~ 3600mAh), the mainstream capacity of even 3500 or 4000mAh have more than (remind you, in the market nominal 3200mAH above the domestic batteries are false, the current mass production of the maximum capacity of 2600mAh. ).Rechargeable Lithium Batteries

     Generally believed that the lithium battery no-load voltage below 3.0V that the electricity used up (the specific value of the battery protection board to see the threshold, such as low to 2.8V, there are 3.2V). Most of the lithium battery discharge can not be no-load voltage into the following 3.2V, or excessive discharge will damage the battery (the general market, lithium batteries are basically used with a protective plate, so over-discharge will lead to protection board detection is not To the battery, and thus can not charge the battery). 4.2V is the maximum charge voltage of the battery charge, the lithium battery is generally considered to charge no-load voltage to 4.2V that is full of electricity, the battery charging process, the battery voltage in 3.7V gradually increased to 4.2V, lithium battery charge can not The no-load voltage charge to 4.2V or more, otherwise it will damage the battery, which is a special place for lithium batteries.Rechargeable Lithium Batteries

     18650 means that the diameter of 18 mm, 65 mm long. While the No. 5 battery model is 14500, 14 mm in diameter, 50 mm long. General 18650 battery in the industry with more, very few civil, common in the laptop battery and high-end flashlight on the use of more. 18650 is only the size of the battery model, according to the type of battery can be divided into lithium-ion 18650, lithium iron phosphate 18650, nickel-hydrogen 18650 (rare), the common 18650 is lithium-ion.Rechargeable Lithium Batteries
