18650 Lithium Battery Parameter 18650 Lithium Battery General Configuration is as follows: The single nominal voltage is generally: 3.6V or 3.7V charging voltage is generally: 4.

20V (lithium cobalt acid is 4.2V-4.3V) * Small discharge termination voltage is generally : 2.

75V, lower than this voltage is easy to cause a serious decrease in battery capacity and even scrap * Charging termination voltage: 4.20V diameter: 18 ¡À 0.2mm height: 65 ¡À 2.

0mm capacity: 1000mAh, some brands will marke 3600mAh or 4500mah and other amazing The capacity, the current 18650 battery capacity is SANYO, can do 3100mAh, but the price is not low. 18650 Lithium Battery Repairing Method 1, Lithium Battery Repair Method One Eraser or Other Cleaning Tools Erase the surface of rust. Lithium battery repair method one principle: Long-term lithium battery metal surface will have a certain degree of oxidation, leading to mobile phone battery and mobile phone, and the use of lithium batteries is shortened, and rubber or other cleaning tool can be erased The surface of the rusty substance allows the battery to contact the phone.

2, lithium battery repair method 2 After all of your battery is used, use temperature treatment, the battery will greatly shorten the usage time in the case of unstable temperature, because the battery is no electricity and a relatively part of the lithium ion already There is a memory that uses such a method to make the memory of the memory, in winter, put it outside, get it in the house. The principle of lithium battery repair method 2: low temperature energy changes the electrolyte of the electrolyte inside the lithium battery to facilitate chemical reactions that have just been frozen. The use of lithium batteries is actually a charge and discharge process.

During this time, the female charge and the positive charge in the battery collide with each other. The battery will be more increasingly not used, because in normal room temperature, the kinetic energy of the electronics is relatively large, so the battery is active, and the leakage is relatively frequent. The lithium battery is placed in a low temperature environment, and the microstructure of the lithium film on the surface of the lithium battery and the microstructure of the electrolyte, and the intersection of their intersection will change, resulting in the interior of the battery, which is not active, and the leakage current is reduced.

So after charging again, the mobile phone will increase. 3, the lithium battery repair method three has a method, remove the battery, put a week, will slowly consume the electricity, need to completely consume the electric power by the machine. Then all rinters, and estimates that your current charging time is definitely very short, after full, disconnect, repeated a few times, absolutely effective.

The principle of lithium battery repair method three: the loop service life of the lithium battery is more than 600 times. If the number of charging is large, the thermal movement of the molecule will gradually be destroyed in the internal molecules, and the storage charge efficiency will gradually decrease. The freezing process is easy to damage the original internal structure of the battery, perhaps the ability to charge charge in a short period of time, but long-term use is not necessarily effective.

Once the microstructure in the lithium battery is destroyed, it is impossible to completely restore it, and this method will use this method to accelerate the loss of mobile phone batteries. The principle of lithium battery repair method three: depth discharge to the phone, is to achieve a deeper and reproduction by depleting internal energy, which requires some unconventional methods. If you want to connect your phone to a 1.

5V light bulb, the amount of power inside the lithium battery will be transmitted to the small bulb until all are light. The phone needs to be slowly exhausted with a lower voltage. Under normal circumstances, if the mobile phone is turned on less than 3.

6 volts, it will automatically shut down. After the electricity is complete, the rechargeable mobile phone battery can be used longer. 18650 lithium battery use 18650 These numbers represent the outer surface size: 18 refers to the battery diameter of 18.

0mm, 650 refers to the battery height of 65.0mm. Common 18650 batteries are divided into lithium ion batteries, lithium iron phosphate and nickel-hydrogen batteries.

The voltage and capacity specification is a nickel-hydrogen battery voltage of 1.2V, a common capacity of 2500 mAh, and a common capacity of a lithium ion battery voltage is 1500 mAh-3100 mAh. 18650 battery life Theory is 1000 times of cycle charge.

Since the capacity of the unit density is large, it is often used in most for laptop batteries. In addition, the stability performance of 18650 is very good, widely used in major electronic fields: often used for high-grade glare flashlight, Portable power, wireless data transmitter, electric thermal warm clothing, shoe, portable instrumentation, portable lighting, portable printer, industrial instrument, medical instrument, etc. Generally, the 18650 batteries are used in industrial use, very small, common, is more in laptop batteries and high-end flashlight.
