What is the standard capacity of 18650 lithium battery?

1800mAh~3500mAh, a small number of which are rated above 4000mAh.

More than 1000mAh, the conventional capacity is 2200mAh-3200mAh.

The nominal voltage of a single cell is generally: 3.6V or 3.7V.

The charging voltage is generally: 4.20V (4.2V-4.3V for lithium cobalt oxide).

The minimum end-of-discharge voltage is generally: 2.75V, lower than this voltage will easily lead to a serious drop in battery capacity or even scrapping.

The maximum charge termination voltage: 4.20V.

Diameter: 18±0.2mm.

Height: 65±2.0mm.

Advantages of 18650 lithium battery:

1. Wide range of applications

Widely used in various electronic equipment, such as notebook computers, walkie-talkies, portable DVDs, instruments, audio equipment, aircraft models, toys, video cameras, digital cameras, etc.

2. Series connection

Can be combined in series or parallel to form 18650 lithium battery pack.

3. Low internal resistance

The internal resistance of polymer batteries is smaller than that of ordinary liquid batteries. The internal resistance of household polymer batteries can even be less than 35mΩ, which greatly reduces the battery's self-consumption. This polymer lithium battery supporting large discharge current is ideal for remote control models, and it has become the most promising product to replace NiMH batteries.
