First, to choose a qualified 18650 and 18650 dedicated charger, the choice of the authentic battery and charger, 18650 battery is also very simple to Xin Jin Yong is designed for single 18650 lithium battery charger, the General cradle charger, as long as the lead from the charger to the charging terminal respectively connected to the positive and negative battery cable on the line, some of the design can be directly used its production of mobile phone chargers. However, there is no guarantee the quality of the charger case worried charger misjudged it? The problem is there, there are two ways to consider remedies misjudgment reference: one with a voltmeter test, if the battery voltage of 4.2V on the line, another method is to charge about 10 hours off, the reason for taking 10 h This value is set by the 18650 battery capacity based. Ordinary 18650 1800 ~ 3000mAh battery capacity range, especially in 2000 ~ 2600mAh up, so choose a maximum of 350mA and 400mA charger, according to the formula: 18650 Battery charging time = battery capacity ÷ charging current × 1.5 (coefficient)
General 18650 battery 10 hours basic full power, because Xin Yong-Jin battery chargers and other manufacturers generally have a constant voltage charge after charge, so 10 hours without regard to overcharge. 18650 battery case if the full standard lithium batteries can also be used for other reference.
Although manufacturers have been considered in the design of the charger charging Article pieces, but we still have to pay attention to some issues charger solve the problem:
1, the standard charge current 0.2C, ie one fifth of the nominal capacity, in accordance with the market capacity of 18650 batteries are generally designed to 350mAh or 400mAh on the line;
2, the control limits when charging temperature below 0 ℃ to avoid charging, otherwise it will seriously affect the battery life;
3, some batteries and chargers protection circuit is not set, it will cause abnormal battery charging, overcharge may affect battery performance, or affect the normal state of the charger, the above mentioned methods to avoid overcharge;
4, when the battery is too low to charge the battery for 18 650 without having to wait until the battery into the termination voltage to prevent over-discharge phenomenon.
18650 applications very wide, held to laptops represented consumer electronics and industrial equipment, medical equipment and other industries of the user, all of the 18650 battery safety, be aware of the importance of the consumer to strengthen 18650 knowledge about the charge, according to the scientific method 18650 battery operation, which reflects the economic benefits in the application to.
