Detailed description of 18650 battery charging method

18650 battery charging can be divided into 18650 battery charging methods, 18650 battery condition setting and 18650 battery matters notes, etc.

The premise of 18650 batteries to be discussed are:18650 lithium batteries and 18650The lithium battery charger is qualified.

Here recommend a "large" brand, brand owners to major big electronics co., LTD., Dongguan city, 18650 batteries and matching chargers professional battery manufacturers, research and development strength in the industry forefront, the company's 18650 battery according to different electric demand of imported or domestic batteries, among them, 18650 chargers with lithium battery charging standard method, after the first constant current constant voltage, the highest end voltage 4.23 V, lowest 4.18 V, in full compliance with standards.

After choose the original battery and charger, 18650 battery is also very simple, to the Dongguan major single 18650 battery lithium battery charger design, general charger, as long as the line from the charger in the end is the cathode respectively received batteries, some design can directly use the production of mobile phone chargers.

However, in the case of the charger quality did not assure charger misjudgment will worry? This problem exists, there are two ways of remedy miscalculation can consider reference: one is to use voltmeter test, if the battery voltage is 4.2 V, another method is charging about 10 hours without electricity, is take 10 hours this value is based on the set of battery capacity by 18650.Ordinary 18650 battery capacity within the range of 1800 ~ 3000 mAh, especially in the 2000 ~ 2600 mAh most, therefore, choose 350 ma and 400 ma chargers most, according to the formula:

= battery capacity present time 18650 battery charging current x 1.5 (coefficient)

General 18650 basic full recharge the battery 10 hours, because the manufacturer such as Dongguan major big charger is generally set has permanently flow after constant voltage charging, so 10 hours need not consider overcharge.

In 18650 the battery is full of the standard can also be used for reference to other lithium batteries.

Although manufacturers in the charger has been considered in the design of the conditions, but we still need to pay attention to some problems in the charger not solve the problem:

1, the standard charging current 0.2 C, that is, one 5 of the nominal capacity, according to the 18650 battery capacity design on the market, with 350 mAh commonly or 400 mAh line;

2, the limit of the charging control temperature, try to avoid charging under 0 ℃, otherwise, will seriously affect the battery life;

3, some of the battery and charger not set protection circuit, it will cause the battery is unusual, overcharge may affect battery performance, or the normal state of spread to the charger, the above said method to avoid overcharge;

4, when the power is too low to 18650 batteries, and don't have to wait for the battery gauge on the termination voltage, so as not to discharge.

18650 batteries have a wide application field. Take laptop as an example of consumer electronics and the user of industrial equipment, medical equipment and other industries, they all know the safety and importance of 18650 battery. The consumer needs to strengthen the understanding of the knowledge of 18650 batteries, according to the science of 18650 battery charging method, which reflects the economic benefit in the application.
