18650 Lithium Battery parameters

The overall structure of the 18650 lithium-ion battery is as follows:

The rated voltage for a single section is generally 3.6 V or 3.7 v.

Charging voltage: 4.20v (4.2V-4.3V for lithium cobalt).

The small discharge termination voltage is generally 2.75V V, below this voltage, the battery capacity will be seriously reduced or even scrapped.

Charging time end working voltage: 4.20V

The diameter is 18 ± 0.2 mm

Height :65±2.0 mm

Capacity: more than Mach 1,000, some brands will mark Mach 3,600 or Mach 4,500 and other amazing capacity, the current 18,650 battery capacity * is Sanyo, can do Mach 3,100, but the price is not low.

18650 lithium battery repair method

Research method 1 of lithium battery repair

Use an eraser or other cleaning tools to remove surface rust.

Lithium battery repair method principle 1;

The surface of the long-used lithium-ion battery will be oxidized to a certain extent, resulting in poor contact between the mobile phone battery and the mobile phone, resulting in a short lithium-ion battery time, you can use rubber or other cleaning tools to wipe the rusty surface of the material, so that the battery and mobile phone better contact.

lithium battery repair method 2

Take down your battery after all use up, handle with temperature, the battery in the case of unstable temperature control will greatly shorten the different time we use, because this battery is no electricity and has a very important part of lithium-ion technology has been developed with memory electricity with this method can make working memory electricity release part, winter is coming, Leave it outside for a while, then bring it inside.
